Srt Intake ?

[Flipaldo]

I was looking at the SRT intake with ECU for the IS300 and the website is claiming gains of 30 hp and 40 torque? They have a dyno sheet but can anyone else confirm this? That sounds a little high for an intake kit.

Well, first of all the dyno sheet shows a 13 hp gain, not a 30 or 40hp gain. And the torque gain is really a torque curve change. It helps produce more tc lower in the rev range, but you lose more above 4000 rpm.

Second, if you get one, DON"T BUY IT FROM LEXTACY!!!, you can go to SRT direct and get it for less.

Third, remember it's an ECU piggyback system. Not just a CAI. You can get 7 to 9 without messing with the ECU with the K&N. And if you plan on adding headers and exhaust and all that, then you'll want to do an N/A tune with a tunable piggyback or standalone anyway, which would make the SRT a waste of money. But if your only going to that far, then the SRT is a good CAI by itself.

I realize the dyno chart shows gains of only 13hp but if you look at the write-up it says a 30 hp and 40 torque gain. I was just wondering if anyone got anywhere close to those numbers.

No, nobody has gotten anywhere near those numbers with a cold air intake alone. If you put that cold air intake, headers, down pipe, and exhaust, you would barely get to those numbers.

That's what I wanted to know, thanks.

Also, keep in mind that the SRT is not CARB exempt, meaning that if you live in a smog state, you will have to remove it when getting the car smogged. I called SRT a while back and they do not plan on develping their product to be CARB exempt. A problem for those of us who live in So. Cal.

I'm fortunate enough to live in a state where they don't have smog testing.
