Results will be from a mustang Dyno. As far as manipulating the dyno people do that when trying to impress someone. I'm not trying to impress anyone. You won't see any fanboy tactics from me. I'm let it do what it do. I'll post numbers, timing, fuel, and boost level. I'll holla back in a month

All based on the word of someone no one knows. Can't you just get some other results to back the dyno? After all you DO look like you're trying to impress us of the Comp turbo line.

Wow. I don't be on this site so of course you don't know me. That means nothing . I could throw some names out there of people that do know me and of people I know but unlike most throwing names out and bragging is not my thang.

You sure are asking alot. Since when has a dyno number not been good enough? It's cool. I'll put out a real nice video for ya with 1/4 mile trap speed and a few other goodies . So I'll post info for those that are really interested in the results. Any other request from the DSM Wisemen? Like I said earlier there is a ton of info on Comp with numbers etc. The situation with DSM's is that there are currently only 3 DSM's running a Comp Turbo. 2 that are builds in progress and 1 that has ran a very fast time at a lower boost level and has been running a Comp for a while now. But they are pretty well known in the Supra and Honda community.


Look at it like this. I'm just trying to give the community more options. That's my only reason. Not because the parts we have don't work or anything like that. But if you haven't noticed slowly but surely companies are not making as many parts for our cars anymore. Like how we can't get the FP 5R cams anymore? Do you think FP would ever allow that to happen with the EVO?

That means something. That means exactly what I said: we don't know you. That means that you could be trying to impress. You could do/be alot of things. Not trying to be negative. But realistic.

Guys around here know that a dyno is a tuning tool. The same number from different dynos can and have been proven to yield wildly varying MPH times. No one trying to impress. No one keeping their sponsorship. The results were still vary random when it came down to who was fast in a real racing environment. So no, it is not asking alot. In fact I'm not asking for it. The above concerning dyno results is common knowledge. And I'm just preparing you for what will be asked from you when you do post any such dyno sheet.

Yes I do agree that some long time vendors to this platform are pulling away a bit.

It's cool. When I get my results I will post them to be analyzed.

Oh by the way here is a good read for ya from someone a little more familiar .

Shop car using a $2700 turbo....now THOSE will be some realistic results for everyday users.

My $500 new HX40 looks better the longer this thread gets.

That's not the point. It is a big money shop car. A potential low 8 sec car. Every car has a different goal and they have turbos for DD. The questions I ask you is why would they run a Comp Turbo (that in your eyes is not proven)? Why not a garret, turbonetics, or a BW (which they have ran on their low 8 sec 4G63 RX7). All i'm saying is do your research. MAP are now vendors of Comp and turbochargers.com have been selling them for a while now. So they must know something. It's a big ass world outside of the DSM community. Like Mikes Turbo Inc, Comp etc places that can run Garrett parts etc but also have their own turbos. I have know about a gang of turbo companies that most mitsu people did not have a clue about until recently. A few mitsu people still know nothing about . But a Rotaries in Puerto Rico have been running them.

Like this company that has been around for over 11+ years that no DSM is running.

Have you ever seen this CHRA? If you have than you would know like Comp Turbo they are no joke.





Now to get back on topic.
I just wanted something different. Are they for everyone? No. The fact is 98% of DSM's will not spend the money on the turbo. Some will. The point is Comp Turbo are good turbos and are another option. In the end that's all that matters.

Becuase 98% of Dsmers are smart and know an HX-40 or HX-52 cant fit their needs without spending $2500 on the turbo....Thats more money than what I spent to build my shortblock.

Their are better alternatives that dont cost that much, Who cares what the damn CHRA color is or how many ball bearings you can cram in their, from what I gather, they dont really spool for shit unless mated to a divided t4 manifold, Nothing like a journal bearing HX-40, and I bet nowhere near the reliability. Ive seen used hx-40's used with shaft play and still run strong while being damaged for lengthy periods

The HX40 is a damn good turbo. But no it does not have the performance or response of a my turbo. Just as the similar size BW will outperform a HX40 everytime. I'm not here to argue or offend anyone. Like the FP HTA 3076R, HTA DSM76, and the HTA68 there are not alot of DSM's running the turbos and hardly any threads. Most of us are cheap and we low, lowball. It's nothing wrong with that. But understand the flip side. That's the same reason why companies do not make parts for our cars and just focus on the Evo and the same reason why are cars are worth nothing. Like I said it is just a option. They turbo can be for DD but they are specifically made for racing. That's all I have to say. I'll be back and post my numbers etc.

Im just saying, the fact that I can afford to spend $2000 on a turbo, but I still would buy an Hx-40, not for the cost, its just proven to make power.

If you prove that this comp turbo, being 5 times as expensive, can out spool, out flow, and make very reasonable hp at decent boost levels, and possibly do my dishes like an hx-40, ill hush up.

Amen to that, I picked up my freshly rebuilt HX52 for a mere $500. I will in no way waste $2500 on a turbo alone to put in my dirt cheap car. Spooling at 20~ psi by 4800 rpm and making 600 awhp at 27 psi on a 2.0 block is good enough for me.

Once I resolve the head lifting I'll be even more happier than I am now boosting higher.






spoolin_ddub don't make this run on any longer until you have the results we'll all be bowing down to you if what you're saying it true. But... at $2500 I don't think anyone will even considering going to the Comp turbo especially after I've look into their previous shop, Innovative Turbo.

Don't bow down to me . 1gDSM4g63 you in Indiana! I be out there all the time. asa matter of fact I know your car. I'll drive my car to you and you can give me your personal opinion. I'll be going to No Limit Raceway for Street Car Chaos. You should come also. Didn't Strictly Modified do the work on your car? You know the crazy way they ran your wastegates and dump tubes off your JHracing manifold. Strictly got that idea off my car . Didn't know that did cha? They called your car my little twin. Yes I know about your car but call them and ask them about mine.

Garrett and Turbonetics are basically the same because Turbonetics either uses Garrett wheels and housings or copies their specs. Comp fits into this category as well.

Looks nothing like the turbo that MAP is using. How much for that fine piece? $5000+?

spoolin ddub said:

Click to expand...

Right, because racing is where things like quick spool matter over total achievable airflow. Maybe that triple-ball-bearing center housing is more durable than a Holset or BW, and perhaps it's transient response is .005% faster than a dual-ball bearing Garrett whose wheel specs Comp has copied directly and happens to be available at half the price, but every race car out there has some sort of launch control and never drops below 5k once it's moving....so the spool argument is out.

That's good to know. I recall Innovative as the laughing stock of the turbo world and couldn't put together a durable setup whatsoever.

I guess copying Garrett and BW wheel specs must not have been too "Innovative".

Uh....Sir,... he didn't pay $2,500 for his COMP turbo. Also, he stated COMP turbo's AREN'T for everyone. Besides that, most DSMer's can't even afford the $1,700+ FP HTA turbo's, so yes the Holsets are good alternatives.

Again, all this HOLSET love nowadays.Thats funny..I didn't hear all this in 2005 when I bought my HX35 from BEP. Guys were saying ''it's a truck turbo'', ''it won't spool'' ,'' just save up & get a 35R''..etc.

The HOLSET naysayer's back then, sure sounded like you guys today in regards to COMP.

What do you mean?? We would have to pay full price for that comp turbo if we were to buy it, around $2500

Well the advantages that holset has over other brands are price and overall potential in a bolton housing. They spool much faster too; because 1) you are able to run small housings to net such high goals, coupled with 2) their dedicated diesel aspects. Other brand's have other distinctive advantages. And yes, an advantage is rooted in the point of view of the builder. So what IS the comp advantage? Price? Maxed out potential? Longevity? Bolton potential? . . . All I see is a rebuildable center cartridge. But I can buy TWO proven 9s PTE BB turbos for the price of one comp rebuildable BB turbo. . . so what IS the builder's point of view? Sponsorship?

Consistant with the above and as already mentioned, the $500 rebuilt hx52 on 1gDSM4g63's car with a basic tune and the same turbine wheel specs spools quite a bit faster than the comp turbo of similar wheel specs spoolin ddub has so far. And obviously, the flow is there though that turbine housing is one of the smallest options for it, since 600whp on a consistant/unmanipulable dynojet was net with an amateur tune (Sorry 1gDSM4g63 ) and 27psi with a 2.0L using a good/basic/known build strategy. My only point in contributing to this part of the conversation: 'Holset naysaysers' said 'cost effective diesel journal bearing cant cut it'; not 'it is too expensive for the output'.

But regardless, when/if spoolin ddub comes back with 750whp and 8s (this is the range that the competitors turbos, PTE/garrett, with the same specs and spool speeds that I see), then it will be proven to MATCH. Considering the price tag, they better exceed. We're not talking $500 for a turbo after it's rebuilt. It's not a good marketing move to offer a MORE expensive turbo brand than all others in a 20 year old automotive performance market unless it WELL exceeds in nearly all aspects.

. . . Yet, nothing comp has is bolton anyway. So a buyer could be someone with 2 grand burning a hole in their account . . . So we'll be waiting. Lets cut the bickering and watch.

Yes, DSM Monster I agree....^
Yes, the 'bolt on' adavantage is w/the Holsets. price? yes again,
Yes, the COMP is VERY expensive, Sponsored , yes sir.
Yes , more expensive & that is not a good marketing move.
Yes , PTE's/Garrett's are proven & cost less than a COMP.
and finally..
Yes, Spoolin wants to run something different & yes the COMP better exceed.
We'll see.....

no one pays retail nowadays.....

I got my ct4372 (.84/mx wheel) thru Velocity Racing Performance (VRP) for $1450 shipped
thats polished with the ct3b chra (retail $2200)
So they arent THAT expensive as they seem..... of course no where as cheap as a holset.
Honestly i think holset turbos are the best bang for the buck out there.
Im definately feeling the precision billet turbos as well.... i was actually a few keystrokes away from a precision 6765 dbb when i decided to go with the comp tbb.

anyways, my setup isnt complete yet so i cant contribute anything 1st hand other than my good friend running a comp ct4376 on his mkiv poopra.... hes making a shade under 900whp and it spools VERY well for a 1.0ar (sx wheel) 76mm turbo.... he has run several setups over the years on his car from GReddy T88H spl, Garrett 4088r, 4204r, 4508r, different borgs, and a bulleye power t6 turbo. He is by far much more impressed with his comp than anything else he has run over the years. I hope to be just as pleased! time will tell.....

617whp @ 26.4psi 67mm comp turbo
YouTube - JESSICAS 67MM SCION TC MAKES 617WHP @ 26.4 PSI SPINNING!!!

Totally just playing devils advocate here... it's not a dsm, but it is a 4cyl engine running a Comp Turbo. I really can't speak for the quality or design innovations (or lack there of) on these turbos. I've only held one and honestly didn't look at it too close. It was off my friends Cyclone with a stock motor with bolt-ons and it pushed that pig into the high 11's if I remember correctly (that was 5+ years back). He never had anything but good things to say about it. He could have just been one of the lucky ones. I certainly won't argue with somebody that rebuilds turbochargers on a daily basis on that subject. The one thing I remember liking about their turbos was that you could rebuild the ball-bearing models. That was a while back, when they were still Innovative, so I don't know if that is still an option.
I'm not standing behind these turbos in any way. I just know that there are negative things that can be said of almost any product out on the market today. We're getting plenty of replies with the negative here, I'm just looking for some of the positives so we can see how it balances out in the end.

I'd consider trying one if I had $2500 to throw at a turbocharger. I'm not saying it's a bad product- just wondering what you're getting for the additional money spent.

Given the choice between a $2500 Comp and at $1700 FP 3586, I'd choose the FP turbo hands down. The standard GT center housing has never proven itself unreliable, so there's no reason to go to a triple-ball-bearing setup in my eyes.

I just can't justify spending an additional $800 to get a turbo that has the same wheel features as it's Garrett counterpart with an additional ball bearing which is arguably necessary.

I don't get where the $2500 figure is coming from. It would seem to me that this $1700 CT367 is fairly competitively priced vs other 700hp ball-bearing turbos.
Comp Turbo
Now if this turbo weighs significantly less and you can get it rebuilt... Those would be two things I'd weigh heavily in my consideration assuming all/most other aspects of the turbo were on par with the competition.

again...... no one pays retail..... that ct367 is msrp at $1695 w/ the TBB meaning you could score it for under $1200

You forgot to throw in one of the best options. Which for me was one of the main reasons I purchased the turbo. They are upgradeable !

The car should be done next week. Talk is cheap and people want proof so I'll gladly post them numbers .
