Engine spec

Stage2 Monster streetport
greddy t78 turbo kit
large fmic intercooler
Microtech lx10s
Exedy clutch
Exedy chromolly flywheel

With this combination i hope to achieve 500hp+ at 7000rpm with 20psi of boost

Well,

from my calculation, you will see something like 380 RWHP at 20PSI and 7000 RPM. This is something like 450HP at the fly.

but, keep us up to date.

^I believe your calculation is wrong.

I think you are low by about 100 hp.

damn Iwan... you sure that wasn't a stockport 12a you were thinking of? hahaha

we have done 460rwhp at 16psi with a large streetport and a T78 and often see 400+ @ or around 14 psi. the T78 is a proven turbo FO SHO!

Iwan

You need to rev it higher..... 7k is not much,

Please add 15% to my calc , as I forgot to add the streetport to my calc..... so would say 430RWHP

But as allready mentioned, keep us up to date.... I may be wrong of cause!

dubulup

Still wrong...

542.5 on the wheel my guesstimate!! good luck and watch the boost at 20psi!!

Wargasm

I will guess 470 rwhp at 20 PSI. This is fun!

^ i agree with water injection you should be able 2 touch 500RWHP but i would expect around 460+ with your set up.

Thanks for all the inputs guys! I am just as you are very curious how much flywheel hp my REW engine can make.Does anyone know where to find fuel maps for MicroTech LX10 for a streetported T-78 Greddy set up? I shall start the engine in my garage first and map idle and low rpm like 2-3000 rpm with no load just to see that the computer works.

just boost little by little and adjust the map accordingly. the microtech doesn't have the capability to just load in someone else's map but it's so simple to adjust it's not a big deal. if you don't have a 3 bar map sensor then pleaaaase be carfeul hitting 20psi as that is the max the internal mapsensor will allow. if you go higher then it will just hold the settings from 20psi and not increase = death

Thank's very much No Rotor RX7 for that info! Today i have buy a lot of AN couplings and stainless Earls hoses. The oil cooler is there and also the radiator. Tomorrow i hope to start it but i must first draw all the electric wires to sensors coils e.t.c and also finish the porting of the upper manifold and a few other things i can' remember. Soon Saturday... gulp!

the photos looked great. any pics of the ports themselves?

i have no guesses to make.

iwan may be forgiven for his estimations as i have noticed that here in europe the readings are lower for the same mods than they are in the US. Even when the same make dynos are used.....I think it is down to atmospheric conditions...anyone car to elaborate.

peachykeenwight

Man, I would be disappointed if I made less than 400 RWHP with any aftermarket turbo setup and a decently well-flowing SP in the 20+psi range.

I think you're looking at the upper 400's, possibly creeping up close to 500 at the rear wheels.

um actually the microtech comes with a 2 bar map sensor witch is equivelant to 29psi.

Lasse wankel

Just home from my garage. I have been wrenching continously for 8 hours with some help of 2 rotary guys. Everything seemed to work out fine with oil pressure coming up soon, no leakage of fuel and start motor crancked for about 20s but no roar in the engine just becausse the starter motor gave up! Sad but true! I am going to pick up 3 more used starters and hope someone is ok so i can dyno today! As they say.. never give up!

You are forgetting that normal atmospheric pressure is already 1 bar, so a two bar MAP sensor can provide information for "normal atmospheric" (1 bar) + 1 bar = your 2 bar.

hondahater

iTrader: (2)

really? Can you explain? I thought one bar was equivelant to 14.5psi and the second bar was equivelant to 29psi. Isn't bar a measure of possitive preasure.

kabooski

no its not 29psi
2bar is like low 20'ish
3bar is like 32psi give or take
