499awhp on a 16G

[red91gst]

What kind of numbers are you making tuning a stock compression motor on 93 pump?

397awhp on 93octane pump and a stock 7-bolt.

Yes sure, we drove the 2G down from the upper parking lot and ran out of gas!

Haha yeah i remember hearing that .Nice 2g by the way .Sound like i need you to tune my car as well.For some reason i thought you guys were from wv.

Our garage IS in Morgantown, WV. I, however, still live in Indiana.

Got ya . How long did it take you guys to drive to gmu? Maybe i could make it up there sometime.Going to be a while though when my ankle heals and get my car back together.

 

[PIMking]

so when are you going to make a trip to iowa????? Cordova drag way eat some of these idiots around here! very impressive im looking to pump out high 11's and I will be happy.

Construction season just cant start fast enough for me to spend my money.

Was there at the track day with Wayno and Curt and I'd have to say it was a pretty crappy day for runs. We were there all damn day for 2 runs If friday is a test and tune at Quaker should have a much better shot of hitting some good times. Car is definately impressive to say the least, even with the bad launches. I have a couple vids of the runs if Curt's interested in me posting them.

I want to see videos! I love how it was a "bad run" and it's still one of the fastest 16g powered dsms ever.

 

[droppinbottom]

Congrats to you.

I do have one question that I did not see asked or mentioned. What kind of dyno was this done on?

 

[SBstar]

Dynojet says so right on the top of the graph.

397awhp on a stock motor (minus cams, like mentioned) on a "standard" EVO III 16g / Internally gated on pump gas, would you care to share the boost level? It may have been posted and I just missed it. congrat's on the 10 sec. pass...

It was a reasonable 20psi...

 

[90laserRSfwd]

thanks

Standard 16g internal wastegate actuator.

That is just insane. We have my brothers car setup so its pretty much a closed wastegate at all times and he hits 28psi and falls to 22-24psi by redline. He has a 2.5" exhaust and we think that may be restricting the turbo from holding higher boost levels.

 

[dsm-onster]

You mentioned a jist of the timing and a/f results. What happened with the boost? 32psi to what by redline? Do you remember where the gauge was hovering at horsepower peak (6-6.5K)?

Thanx

 

[jkimes]

Wow, those numbers are awesome and depressing at the same time. If my car wasn't at polk performance being tuned as we speak I might consider driving it to Indiana for a TPG tune. I've got a laggy ass scm6176 as well as a built 2.4 and I'll be surprised if my car makes as much power as your freaking 2.0 16g

 

[kraka]

I find it VERY interesting that the car is making it's peak power in the 7k+ range on a 16g (pump gas map). Usually they are running out of steam by then. Super linear power curve, I like

 

[dsm-onster]

The 599whp graph is VERY interesting. Peak power at 6300rpms and loses 50hp by 7K. It's down almost 100hp by redline. But still above 400. Ends about the same as the pump gas pull. Just a WHOLE lot more in the midrange. The first graph looks like a typical 16g graph. Just some special "Curt Brown man juice" under the hood putting the curve alot higher. The powerband is nice and broad. Did boost blead down to 22ish like in the 460whp pull on the stock block?

 

[kenamond]

Overachievers just depress me.

I went to WVU '89-'95. Competed in FSAE (N/A M85 CBR 600F3) which headed me in this direction (we got 5th in the acceleration event - I designed a variably-tuned intake that we blew up on the dyno from wasted spark, valve overlap, and M85 fumes , but the replacement got honorable mention at the competition). You guys ever contribute to the WVU FSAE team, knowledge-wise? They may not even do it anymore; rumor has it that the dean of the MAE dept. back in the day funded FSAE out of pocket, but he wasn't a spring chicken even then and's probably retired since. I worked for a summer in WVU's engine test facility and watched a Mack turbodiesel throw a driveshaft across the dyno bay along with the bell housing. Fond memories.

P.S. Rodriguez is a punk.

P.P.S. You obviously know w.t.f. you're doing.

 

[dsm-onster]

Ok so. . .

The powerband is nice and broad. Did boost blead down to 22ish like in the 460whp pull on the stock block?

And which head is this? 1g or 2g. . .

 

[jshuman]

So where do you actually do the tuning , Indiana or your shop in Morgantown?

I live in vienna, thats less than a 2 hour drive from Morgantown. I am about to start re-tuning my 50 trim setup, but if I can't get to where I want it to be, I may have to use your services.

 

[dsmrunnah95]

Very impressive

 

[90laserRSfwd]

It doesn't matter what motor, tune, etc. take some time to let it sink in..... 499AWHP ON A 16G... A year ago everyone would have laughed at you and called BS. That is truly an amazing accomplishment. Nice work.

actually on his last numbers he was called out on it and that was a few months back. He said he would be back with 500whp+ and was so close. Very impressive indeed. I talked to my buddy Jack down at jackstransmissions.com and he was telling me about some guy that made near 600whp on a 16g but I never could find info on him or the car.

So I have always ran a stock 6-bolt bottom end. 7.8-1 compression.
My recent engine builds with the honda crowd, which range anywhere from 8.8-13.7-1 have made me wonder why the DSM crowd doesn't usually up the compression more than 8.5-1 or even 9-1?
A friend I work with is dead set on building turbo hondas with 10-1 compression.
I have heard/read in the past that anything over 10-1 is not suitable for boosting, such as 10.5+.
His B20vtec 35r powered SI hits 20psi at around 4400rpm.(520whp on c16, theres more but it was a quickie tune).
Back to the point.
What has kept us DSM'ers from using 10-1 pistons?
I have been on this board for YEARS. And read probably every post thats on this site.
I had always believed that 8-1 pistons and more boost/timing was the answer,
Now I think I have changed my mind on that issue, even up to 10-1 and 20psi seems to be the fastest to me.
(this goes along with WHY 500whp is achievable on a 4g63)
I for some reason think us DSM'ers have been pushed into buying 8.5-1 pistons for soo long,
The whole "turn up the boost" theory is good, but not the most powerful.
Anyone else think the same?

[bacalhau16]

I agree with you fully. I think that there is a set way of building your car here and thats it really. Low compression, bigger turbo, (E316g for the most part) and DSMlink is always a must. I just feel that there is a lot of other options out there and would prove just as good if not better. Higher compression would be great. Faster spool, more power and if DSMlink is gods gift, then it should have no problem tuning it out.

 

[JeffGST]

The reason why many DSMers are pushed into 8.5 to 1 pistons is because they are pump gas friendly pistons. Users who drive their cars everyday to get them to work and to the bank, market, night out, track etc... most likely use unleaded fuel.

8.5 to 1 piston are just very FORGIVING pistons that most novice tuners can use so that they can get away with a lot. A more savvy and experienced DSM tuner will embrace 10 to 1 pistons and use them everyday. If you want to break records with individual turbos, then the higher the better.

Now if you have Ethanol readily available to you, there is no reason not to go at least 9 to 1 or even 11 to 1 if you wanted to. E85 is just as knock resistant as C16 is.
