New FMIC tomorrow - need some advice pls

[Flaps]

Tomorrow i get my new FMIC (Trust V-spl) installed and i am having a few thoughts about the increase in power.

It was Nissky's old car.

These are my current mods: -

RB20DET

R34 GTT Turbo (T3)

GTR fuel pump

Remapped computer

Apexi Super AVC-R (first edition, the black one)

2.5 inch turbo back exhaust

Air filter and BOV

Im running 2 levels of psi, 10.5 (.75bar) and 13.3 (.95bar)

Now my question is, with the new bigger intercooler, i should have 20-25kw more(correct me if im wrong) - will my engine/turbo be able to support these mods?

I really dont want the turbo to start leaning out and do rings

any help would be appreciated!

Cheers

Sean

hey man sorry to get off topic but i was just wondering what power ur getting out of the current mods, or if u dont know the power what 1/4 mile time does it do

cheers....brett

ill be able to tell you after i get a dyno tune on how much power and not long till i go for a run down the creek

since when does adding a fmic increase HP? didnt for me, allowed me to run more boost in hotter temperature without detonation.

[Flaps]

Ive heard that installing a bigger FMIC allows the turbo to breath better, resulting in around 2 psi drop. Having a boost controller will keep the amount of psi at the same level it was before the bigger FMIC. Which should increase power levels.

Well that is what i have been told by people on this forum.

I agree with you rob77 when you say an intercooler allows you to run more boost safely in hotter temperatures (cooler air therefore less chance of detonation at the same boost levels). However I also thought that if you installed a decent aftermarket intercooler over the stock item and didn’t change anything else (boost levels etc) you would still get a performance increase due to the cooler and slightly denser air being inducted. Someone correct me if im wrong, only way to learn.

[rob77]

I didnt dyno my car before and after I fitted the fmic, the only difference I noticed is that the car wouldnt ping on hot days when my boost controller was set at 12psi. You might gain a few HP but nothing as major as 20-25kw's that he posted originally.

I think once u install the cooler because there is less pressure drop u will be getting higher boost pressures at the manifold, so more power. Even if u dont tuch the boost. Not 20-25kw though. Could be a reason.

when i had stock cooler, safc, exhaust i got 155rwkw with 12 psi boost

I then threw on a 600x300x76 cooler and ran it on the dyno again without changing any setting on the safc and i got 183rwkw.

The standard cooler is a pile of poo and does not cooler the intake air/not drop pressure as much as a decent sized cooler, ie cooler the intake air = more power.

got it fitted today, looks sweet as and it goes alot harder.

:wassup:

did u put it on the dyno flaps?

[Guest Robo's]

Cooler air = more power, simple really, cant wait to fit mine on next week and then off to do some serious tuning out of the stock turbo and then hitting the track, hopefully for a flat 13.

[rob77]

Funny that the fastest r33 on a stock turbo was run by a guy with a stock intercooler too. talk to rev210 I think it was a 13.3 on the stock turbo, intercooler, ecu and on 205/55 tyres. According to you lot with a bigger fmic you should go faster because your making more power right?

[Guest Robo's]

Well if i cant beat my time, i will go he!!

I havent got huge kw's, and my terminal speed is not alot either, give me more top end please..

On my runs, my car was pinging badly in 3rd and 4th. If i can stop the pinging and get some more rwkw, a good time will be on the cards. Traction is the key and some quick shifts!!

[wreckedhead]

why dont you try the water injection kits that are sold at MRt, for 1000 dollars the aquamist will qaurentee your car wont ping through the gears at higher boost therefor giving you more power...... just a thoguht.

[Flaps]

did u put it on the dyno flaps?

I will be soon, just to check air fuel mixtures and see how much power i have

Also the possibility of running more boost

[bretto]

well let me know when u do, ill have the new turbo goin on either tomorrow or next weekend so i might kno what ill have anyway (putting r34 turbo on) but it will be good to compare.
