1st Dyno Results after rebuild!!!

[V8slayr]

My setup:T3/T4 50 trim, .63 ex, stage 3 wheel (journal bearing)Peakboost manifold/ ISIS intake manifoldHKS 264 step 1 cams/ Peak performance valve springsDwerks 740ccEnthalpy ECUCP 87mm 9.0:1 pistons, stock rods/OE bearings/ARP rodbolts

Dyno done on local dynojet

394rwhp / 300rwtq @ 18 psi on 93 octane

Shut it down at 7300 rpm, limiter is set at 8,000, would have seen over 400 if I would have not pussied out.

Your car is fast.

Where did u get the 50trim turbo?

[S14toRPS13]

Nice numbers. You got any dyno sheets. I want to see the power band.

Very impressive. Did you feel like the .63 housing was starting to choke out past 7Krpm? I just bought a GT30R (without a housing) and want the .63 ar for spool but don't want it to be to restrictive for 430-440whp. Post your dyno plot when you get a chance. Here is mine with the Hoslet HX35 with a log mani, 2.5" DP, and basically everything else the same except JWT rom tune. I was at 23-24psi but the difference maker was the cheap log mani and 2.5" DP if I had to guess. Tubular mani and 3" DP and I could hit those numbers with 4-5 less psi.

I got the turbo from turboelements.com about 10 months ago.I do not think the .63 housing is restrictive at all. My graph was still climbing when i shut it down, and on the street the car keeps laying on power the higher you rev it, it feels like it would pull to 9k if I wanted it to. I'm also running a 2.5 in DP and am looking forward to changing it to 3". Down the road when i get a little more comfortable w/ the motor I plan to dyno around 22 psi on race gas, and hope it makes between 420-450.

I do have the graph, but I'm not too good w/ computers and don't have the faintest clue how to post it.

I'm kinda wondering why my torque number is so low tho, Kentucky your setup is close to the same except the ex. mani and you made 40 more ft-lbs. than me??

[V8slayr]

You know what tho, my boost creeps like hell and at 5-6k where it made max torque the boost was only 15-16 psi. I'm running a 1 bar spring and no boost controller and it rises to 17-18 psi and holds steady. So anyway, if you look at it that way that torque number is really for 15 ish PSI, compared to the the HP number at a full 18 psi.

[kings_club]

hey how much boost can i throw at a stock motor?i have a gt28rs on my silvia, and i want to get it tuned.

a buddy told me all i need is a z32maf and injectors to make like a solid 300 wheel.is this true?

[240life]

You would need a tune to control the new injectors and maf also

I was running 6 more psi. I made about 300tq at 18psi after I installed the ISIS mani. Your peak boost mani is good for 30-40 more whp at the same boost than my log mani. I will have my GT30R on tomorrow and I think it will be much better than the HX35.

[V8slayr]

I agree, the GT30 will be much, much more efficient at the boost you want to run and should make hella power. I'm going to the dragstrip tomorrow night on some hoosier autocross slicks, ha ha. They should hook up pretty good though straight up. Hoping I see a 7 sec pass!!!! and trap at least 90 mph!

[domiballa]

so how has that isis manifold worked for ya?

[kings_club]

well yeah of course i know that. lol

how much am i looking to spend for a solid tune?and anyone know anyplace in the southeast who does tunes?

[domiballa]

just get an enthalpy romtune 550cc injectors and z maf you should see 290-310 whp no prob as long as no leaks and such..

[V8slayr]

As far as tuning in the SE close to where we are in AL, the only place I know of w/ reputable tuners is Atlanta. There are a ton of shops over there w/ badass tuners. I am a fan of the Enthalpy ECU though. The way my car runs is like it's completely stock, AFR is perfect under all loads/conditions, and it makes good power. For a mail order tune it works tremendously well.

[kings_club]

alright thanks alot.how much is the enthalpy guys fee?

[timmyk]

nice numbers man, cant wait to get my sr in
