    The FP bolt on housings do flow better than 7cm^2 mitsu housings and bolt-on PTE housings. The FP housings make the scm series housing look like a schoolboy bi***, even my bullseye housing makes the scm series look bad.

    I went from a tdo5 housing 18g turbo that spooled around 3400rpm to a p-trim turbine, 65lbs/min turbo that spools at 4200rpm. The larger turbo is a much better daily driving turbo IMO.

    Um no kidding if you are bitching about 300rpm being the differnce between a good dd turbo and a bad one maybe a t25 is what you are after:notgood: How many people would care about 300rpm when you have more power pontential and over all a better turbo?

    That is fine you say that's your opinion and that's fine. I'm not trying to down anyone's opinion on here unlike other members just trying to point out how I feel about t3 housing on BIG turbos not just any turbo. Last time I checked this was a poll not a debate forum

    ROFL This is funny coming from a guy with no mod list and probably hasn't even run a t3 or bolt on housing this size:rolleyes:

    I got a couple 1000hp dyno graphs I found online click here to see what my X turbo did on Y car :notgood:

    Random links do nothing to prove anything. Not to mention the second car didn't hit full boost till 5200 but it doesn't even matter because there is no car info video or even the person whose car it was to vouche for it.

    What an excellent argument.

    We're all showing you proof of cars, you've shown nothing to back your argument up. Aside from compression ratio, suicidal2af has provided some good examples. On smaller motors they're still spooling fast.

    I believe 1SloColt was running an GT40/P-trim setup. (SC61 variant in a Bullseye housing.)

    I have no idea why I remembered that. ROFL

    What do I have to argue for. I made a factual statement bolt on hosings spool faster and are more streetable. Now if you think full boost at X rpm is fine that's you and who am I to argue but I don't think that spool past 4500 is fun for a car you drive everyday. That's my opinion i'm not arguing anything. The only thing i thought was naieve of you guys and mad me even waste the engery posting is that your on here saying the bolt on housing can't make ggood power which is bull. I just don't want every new dsmer to come on read what you guys are typing and not hear the other side.

    Problem is, bolt on housings tend to be peaky and drop quickly up top. What good is a 65 ln/min compressor if you can only rev to 7000 before power dies?

    Don't get me wrong, I fully understand what you're trying to say. Guys like Curt Brown went 9's on a TD06H housing (FP Red.)

    Problem is, big power bolt on guys are very few and far between because of the way the turbo's make power, hold power, and support power. The big power guys we all hear about are the people pushing the limits of whatever they're running - far from the average user.

    We, on the other hand, are showing that every day cars with T3 housings are pumping out better numbers, while still maintaining fine drivability. Is there a slight spool sacrifice? Sure, maybe a few hundred RPM (as I noted earlier,) but I'll take 50whp for 300RPM any day of the week.

    That is cool. I can live with that as that's your opinion and everyone is entitled to their own opinion. Thing is I think we have a diffrent opinion on what good hp is. If my car makes 500whp and then drops to 430whp cause my hosuing isn't cutting it that's still more power than 85% of the people on tuners. I don't think that a bolt on housing is as inadequete as you guys make it out to be and I will have dyno and flow bench numbers for everyon in the next month and will post a big thread about both my exhaust hosuing and my turbo as both have been constantly doubted and the only way to settle things are to compare.


    Edit: I haven't been on here a year and i've posted 500 times!! I need to get out the house more

    "Streetable" means different things to different people. AMS has a steet driven GT-42 powered EVO with 800+ WHP. Several folks out there with street driven 600-700WHP FP3575s. Than again there are people complaining that their 250HP 16G spools late :rolleyes:

    Ask any turbo builder, bolt-on housings are compromises. You get a more affordable turbo with a one-size-fits-all turbine housing at the expense of some performance.

    Does this mean does this mean "bolt-ons" are bad? No. Not everyone can afford a full-Garrett or FP3xxx, nor will everyone run a turbo at 90% of it's potential.

    But if you do have the budget and don't like compromise, the choice is obvious :dsm:

    Most of the bolton turbo work well if they have a over sized turbine wheel than normal for the turbo. But having choices in turbine a/r and turbine wheel sizes are the best way to do it but not everyone has the $$ to have everything setup perfect.

    I run a variant of the sc61 as coup D E'tat mentioned. Its a gt40 compressor mated to a bullseye housing and they threw in the good size p-trim. I'm at 20psi at 4250rpm according to my logger. The rest of my sh** is basic bolt-ons just to support that turbo. Medium sized front mount, gm maf and translator, Tial 44 on custom designed O2, Tial BOV, 3.5" exhaust, ported 2g manifold, bone stock 1990 longblock including stock 90 junk cams. Car does ok up to about 25-26psi, then it starts getting rediculous after 26psi. There is a guy on here from canada running an scm61, trapping 139 on boost alone. I'm sure he's at the limits of that bolt-on housing cause I know the compressor has more left in it but for a bolt-on housing thats some pretty nasty trap speed.

    Thanks man I didn't know what WE were talkin about. I mean it's not like I've been posting the whole time and know what the debate was over or anything. :rolleyes:

    I know we're talkin about big turbos and by the way I have one;)

    DSM90AWD You are a very wise dsmer but I think you got it backwards bolt on hosuing turbo's usualy cost more than t3 hosuing turbos because they're harder to make work. My gt14 brand new from sbr with my pro shroud t04s cover ported exhaust side and install kit sis 1600 bucs!!!!. I could have almost went and bought a dam gt42 with that money. ROFL


    Edit: I"m sorry I was wrong the t3 hosuing varrient is 17 dollars and change more.

    Nobody said they didn't have there place, or that they were rare. I have a decent sized turbo with a bolt on housing. I don't really like it. I've ridden in and tuned cars with larger T3 housings and spool is similar and top end is totally different. You aren't going to see a huge difference in spool time if everyting is tuned properly.

    Truth. An oldman told me that once (ok more than once) ;)

    Forgot to add in the T3 Manifold, T3 O2 Housing and External WG. This shiiite gets expensive OMG

    I changed out all that suff anyway. To the guy who said that no ones said they were rare your wrong go back coupe said tand I quote "
    Problem is, big power bolt on guys are very few and far between because of the way the turbo's make power, hold power, and support power. The big power guys we all hear about are the people pushing the limits of whatever they're running - far from the average user"

    That's why I made that statement in my previous post. Listen guys we talk about average do you guys realise the TRULY average dsmer looks at 4300rpms full boost as rediculous slow because the TRUE average dsmer is running a 16g and some basic bolt on mods. I know i'm a crazy bastard and spent over 8k on my car in less than a year. I hear from everyone that I should have bought a new car instead :rolleyes: lets hear them say that when i'm running 10's:rocks:

    I have high standards ;)

    But, a 35R isn't really an "average" turbo, although more and more are popping up.

    Its pretty much commmon knowledge. There a LOTS of people to make close to and over 600whp with a the FP turbine housing, where slowboy is the only one I have heard of to do it with their stuff. Also, consider it was made when there was snow on the ground/dyno (if you have any dyno experience you would know the numbers are a good bit better when it's cold out, let alone cold enough for snow to stick around) and it was also done on a hub dyno, which can be optimistic.

    The PTE and SBR housings are just fine if you are looking for a modest power output. If I wanted between 5-600whp, the only bolt on I would think about would be the FP unit. Even then, you will see the power at less boost in a big t3 or t4 housing.

    They are standard operating procedure in this area. If you don't run a turbo that's flowing 60-70lbs/min around here you'll get walked on.

    Well I race riced out civics and things of that nature with 350hp I could walk on most of the ppl around meROFL So even if my turbo which I think will make 500whp only puts out 450 or so i'm still more than happy:rocks:

    By the way coupe your standards are like saying you'll only date girls hotter than jessica simpsonROFL
