Perfect Turbo

[ITR_KILLR]

so its not exactly the same turbo i have listed above? will you list the rest of the setup on that car along w/ quarter times and speeds, it looks very impressive! what are the future plans for it?

[mattback]

the car has not run at a 1/4 mile yet with traction, but it has trapped @ 125mph on an old setup with 380 whp. so it should do 130? mph now.

We're having exhaust manifold issues right now. Hopefully a company called full race can deliver. enjuku/hot shot had a few issues.

[ITR_KILLR]

so you were using the hotshot/enjuku mani? hmm, i was going to ask what manifold you were using. is the new manifold tubular or log style? 130mph trap, that could get you low 11's with traction. good luck, I'd like to know more about the car

[Dori Dori]

It's a tubular...but what problems did it have? That was the mani I was hoping to run...that or a custom mani from a shop here in miami. The hotshot is too expensive anyway; I could get a custom for less than that, but I like the design.

[Dori Dori]

Thats all i was saying : )

My point is, it wasn't the fault of the motor being weak or not being able to handle 400+ horse. It was the fault of an oversight by the tuners. Personally, I would never attempt to double a cars hp without changing the headgasket to something a little more solid...but that's just me.

[ITR_KILLR]

what about using a log style manifold. i know 2 people who make log style manifolds that i would look into

[mattback]

it wasn't really a fault nearly as much as it was a ( I wonder just what it's going to take for this headgasket to go..) and it didn't really blow the headgasket apart disasterously , it was lifting the head.

The enjuku is a great manifold, but we just chose to go with another manifold for different reasons which will be kept off the boards.

So do you, Mattback, stand behind that manifold 100%?



I think the members would appreciate your 'reasons' being told, it could help them.................

here is a pic of the http://www.full-race.com manifold being test fitted on my car.http://www.imagestation.com/pi...3.jpg

Can the SR20 be o-ringed? if so, why doesn't anyone do it?

and matt, it must be nice to be able to destroy SRs for fun. It adds to your credibility as a skilled tuner too....

[mattback]

well, the car was making 409 wheel horsepower on stock cams, stock head, stock headgasket, stock block, pump gas no less, on 555cc injectors.

if we didnt have skills as a tuner the car would have blown up long ago. the fact that it ran for almost a year kind of stands behind the fact that we know what we're doing. I know many who have destroyed SR's at less than 350whp, running for alot less time.

I don't see why the sr20 can't be oringed. in fact, the motor that scotts building is going to be sleeved and oringed.

Being at the top and being innovators does make it difficult to always have things go 100% as planned.

[ITR_KILLR]

how bad is the spoolup on the GT35R??

[mattback]

you tell me.

full boost (18psi) at 5050 rpm it looks like.

not too bad when youre spinning it to 8.

[ITR_KILLR]

are you the guys running Nissdata? Ya, not too bad, not any worse than big t3/t4's that make less power, anyway, after its spooled up in first, just keep shiftin and hold on

[I H8 UR DSM]

well if you do it right, and get some MTS rollers to rev up to 10,000rpm..... ; )

[mattback]

no, haltech E11

[cardinal]

So, to sum it up... What would be the perfect turbo:

1. For drag racing...

2. For road racing...

I suppose the spool time would be the biggest difference between the two - the road race car would need the quicker spool of course.

[I H8 UR DSM]

To sum it up ....for everyone...THERE IS NO SUCH THING AS THE PERFECT TURBO...if there was, there would only be 3 turbo's for sale, not 400....its going to be different for each individual situation...heres the concrete answer

1. Custom turbo.

2. Custom turbo.

Dude I am going to design a snap on/snap off T25 flange and sell turbos in super value packs of three, each one for a different type of driving. That way I can switch them out for the D1GPTIMETRIALSDRAGSHOOTOUTCARTRIATHALON

[I H8 UR DSM]

from now on my answer to everything is HKS T-51 : )

[Gladius]

Sorry to dig up such an old thread.

But does anyone have any experiece with enjuku's 1.1mm metal headgasket?

[turboex]

Im running a precision SC61, has great spoolup time for its size and should be good for the 400pluss im shooting for down the road.

[Tai Mai Shu]

Precision turbos are good, any of the GT25R's with the proper tuning can hit 450rwhp, and Enjuku is running there 1.1 on there race car making 500bhp now.

[turboex]

yeah im feeling the precision, but im stuck on the Problem of 90% on sr20det owners, what ecu to get? I want a good price, and not a ton more features than i can or would every like to use. I would also like a ecu that anywhere can tune, kinda like the hondata, i guess for now im holding out for the aem. oh well any ideas?

[Tai Mai Shu]

More likely then not I would say that Haltec is your best bet, or if you want something simpler go with a SDS. Anywhere should beable to tune these 2 standalones.

[turboex]

wats sds?

[Tai Mai Shu]

Simple Digital System

[turboex]

how is tunning on one of these, the website does not show anything about using a laptop for beter vision of the fuel map.

[Tai Mai Shu]

all on the dyno your best bet for good tuning is tech 3 or haltec.
