Ase Upgrade Intercooler

[Romulus]

Very interested on the results you obtain. I have done EDIT with Injectors and getting 266RWKW, I want to install this intercooler and exact exhaust combo of SMB pipe/cat to factory centre muffler exhaust.  Will you keep the boost at 12 psi ?  Have you or will u upgrade your fuel pump ?

<{POST_SNAPBACK}>

I'll run the boost to 1 bar with that setup, and will probably replace the in tank fuel pump too.

So u changed the injectors back? And there is a difference in the shoot out mode from 6 to 6F, try it.. No they dont all read the same .. all though they should lol

What purpose would that serve? I've installed bigger injectors to make more power, not for cosmetic purposes.

the purpose it would serve would be to do a correct base power with changes to prove a products worth it should be done on the same dyno in the same shoot out mode with the same injectors and everything else.. Other wise its just not really the same is it

Intercooler update: Took the car to have the clutch fitted today, then ran it across to PSI Performance in Wangara to do some preliminary testing on the car. Results as per attached dyno sheets. I made a point of having the AFR's printed on the dyno runs for those that are interested.

With the stock intercooler the car made a base of 209rwkw, now the base is 228rwkw. That's a 19rwkw gain with the intercooler only. 10psi program made 255rwkw.

Running 12 psi boost, with the bigger injectors and the Street Tuner Intercooler (stock exhaust, valve springs, intake box, stock manifolding) the car has now made 288rwkw. I initially thought one of the flash tunes was a 15psi tune, alas it turned out to be only 12psi. There's more power to be had in both the 10 and 12 psi programs by getting the AFR's to around 11.6:1, and adding a little more fuel where the run starts. That's something that will be addressed next week.

Next week the SMB 4" dump pipe and 4" cat will be installed, and car retuned to see what results can be expected.

I'm afraid to say I may reach the limit of the engines internals with the mods I've done running 1 bar boost pressure 

Time to start planning for valve springs, conrods and pistons 

Thanks for the update. Keep us informed as you go.

I don't think this has been answered before, if so can someone point me to it:

What is the standard intercooler piping capable of?

In a real world situation (ie:not a one off dyno run). Or should I say reliably?

Thanks, Brett.

Good question, and one I have been trying to find an answer for as well. Before I spend $700 + on the boost pipes (such as the pipes offered by DiFillipo) I want to know when the stock piping becomes a restriction.

Anyone running 300+ rwkw with the stock piping?

<{POST_SNAPBACK}>

plenty of guys running 300+ on std plumbing but that's its limit of eficiancy.

infact gains have been seen from 240rwkw with shorter well placed plumbing!

if you were to buy aftermarket plumbing find the shortest most direct plumbing you can find keeping away from exhaust manifolds and not just replacing the factory with steel!!!

ps if you did want difillipo's a customer has just taken some off!!!

for the mods this is a customers parts not mine and if you wish edit and remove this part!

Another further update: Installed the SMB 4" dump pipe and 4" cat, so the mods done to the car are as follows:

Bigger injectors

BMC Airfilter

100mm 2nd CAI

Street Tuner (ASE) Intercooler

SMB 4" dump pipe

SMB 4" cat

The engine retains stock valve springs, stock exhaust system after the cat, stock thermostat, stock intake piping, stock intercooler plumbing, stock BOV running on BP Ultimate 98. Of course, tuned with SCT Advantage Dealer Custom Tuning Software.

Power has gone from 255rwkw @ 10psi to 285rwkw @ 10psi, and from 288rwkw @ 14psi to 311.2rwkw @ 14psi from the SMB dump pipe and SMB cat installation, without changing the tune. Tune will be looked at during the week.

Graphs attached.

still thinking I'll go this route prior to summer, unless BP gets replaced by a new 6 speed auto

Great result from the Intercooler install there M6. Glad you are happy with it!

Thanks for the update again M6 XR6T, very impressive numbers.

If you don't mind me asking, what price did you pay for the SMB 4" dump and cat.

$1000 including freight to Perth.

Great results mate!

I wouldn't think that the stock exhaust would just bolt straight up to the SMB 4" cat. Could you please tell me what you have done to make it fit?

Cheers.
