Power increase with large Front Mount Intercooler?

[GILTY]

I'm getting a big Front Mount fitted in a couple of weeks and am curious as to what increase in performance I will get???

I have just shy of 200 Ponies at the rears which is OK for now, but want more.

Will it be laggy with the current 0.9 BAR boost?

Will my BOV be louder as it is already quite loud?

[meggala]

you will gain no power jsut more consistant power I wouldnt fit a front mount till Ihad changed turbos personally

I concur Meggala! But under my current driving conditions I feel that the reduced induction temps will keep my engine a little healthier and therefore more responsive to ungrades in the turbo area soon!

Plus the look of the cooler is gold!

I have earmarked $1,500 for a fully set-up T28 from a 200sx running 1.05 BAR boost, and reprogrammed eprom

[benm]

just dont go tooooo big.

[GILTY]

Never

[meggala]

dont fit a t28 1 they dont fit and 2 there are more suitable turbos for a similar price

I gained about 6rwkw on about 1psi less boost. Mine is only a samll 450x300x75 core.

[adam 32]

yeh dont use a T28

if you want a budget upgrade try a RB25 or a VG30 turbo

[GILTY]

How much can you pick up a RB25 turbo for or a 300ZX turbo for?

What kind of performance gain is possible on either of these turbos and where can I get one?

[slip]

an RB25 turbo IS A T28.

Meggala - t28 doesnt fit in place of t25 on rb20det?

[DCIEVE]

no they are very different

[rb26dett]

standard GTR turbos are t28s rite? and r these smallish turbos??

[Dr_Drift]

Guys..... T25 and T28 are the same flanges and appear on CA's SR's and RB26's, RB20's and 25's run a T3 flange..... As for the cooler we just ran 396 rwkw through a stock 33 GTR cooler and lost around 15 kw on subsequent runs from heat soak. We could touch the cooler and it was still cold with inlet temps of 65 degrees?? As it turned out there was a lot of heat soak in the inlet manifold of the RB26....

Just some food for thought....

[meggala]

hey slip you better tell that to the r33 turbo's sittingon my r32 and my cefiro

I too found the power increase from a fmic VERY disapointing. You will need more boost to feel the difference.

Cant quantify this response with a kw figure, as I didnt do before and after dynos. What I can do is give you a seat of the pants idea of what happened when I fitted a coola.

I had already fitted a powerfc, but it wasnt tuned as the cooler was going in and I didnt want to pay for tunes twice.

I fitted a 300 x 600 x 76 hybrid (sydney) coola. As soon as I drove the car - on the way to the dyno before the power fc was tuned - I noticed when I put the foot down the usual urge was gone - because I was frying the clutch

The difference was pretty amazing. By the time I got too the dyno, trying to drive gently in traffic, the clutch was smoking. The dyno was only successful to a point as with boost at 0.85 bar.

Can only say that I found it an excellent upgrade, with no down side - greatly improved response and power. Didnt notice any increase in lag.

I can only recommend it.

Yeh i noticed a definite improve in response (may have been because I was runnning no bov b4 cooler), but power gains very minimal

[Guest INASNT]

Well before i put on cooler on i had 155rwkw with s-afc full exhaust and pod and around 12psi. When i put the cooler on and retuned the s-afc it pulled 185rwkw on 12psi and 164rwkw at 7psi.

R33's seem to gain more power with the cooler upgrade than the r32, might be sumthing to do with the ecu's

An intercooler is not necessarily give u a massive power hit all on its own. As inlet temperatures are reduced you can tune it slightly better without risk of detonation, so you may get a 10-15% improvement on just the intercooler alone... but it may not be noticeable, and you may get some lag which will counter that small gain.

Where it really comes into its own, is when you up the boost, you can do so much more reliably. Most (aside the freak cases) with a pod/exhaust/fmic and 10psi or so boost can get around 160-170rwkw. Then if u get some type of aftermarket management, and can get it running 12-14psi you might be looking at 180-200rwkw. After that, if you choose your cooler wisely, it will be a good base for when/if you replace your turbo.

The stock i/c on the 33 is so tiny its silly...

[GILTY]

Correct Predator 666, I am just deciding whether to go for the 800x300x76 cooler from Power Digga in Sydney or the 600x300x76.

I have been told that the 600 still flows a truck load more than my current std cooler, and the 800 may just increase the lag a little too much.

I think that the 600 cooler will deliver a good base for future upgrades turbo as I don't want to go CRAZY!!!

Thanks for the responses guys!

Has anyone bought a VG30 Turbo as an upgrade for a 32, where can I get one and for how much (can fit myself-with mates)
