Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

semtex · 04-01-2010, 10:46 AM

Update: I just spoke with Tony, and he has confirmed that if you're planning to keep your car NA, there is no need to ceramic coat. It will make no difference performance-wise (in an NA car), and the headers aren't near anything heat-sensitive like fuel or oil lines.

Once again I am thankful for your clarification Semtex.

Here are my before and after results:

7AT with Stillen GENIII, F.I. CBE with HFC's, 18" resonators, CF mufflers

Before UpRev

Max TQ = 243.0
MPH = 68
RPM = 3267
Gear = 5th

Max HP = 267.4
MPH = 149
RPM = 7132
Gear = 5th

After UpRev

Max TQ = 248.0
MPH = 69
RPM = 3308
Gear = 5th

Max HP = 289.1
MPH = 144
RPM = 6877

The tune was done on an Xact Dyno which for those not familiar is a hydraulic dyno (no rollers)
Tuner said the car put out 342 HP on one pull in 4th gear

Also got the paint detailed (clay bar) and powder coated the Rays wheels black (car is magnetic black). Will post pics soon (wife agreed to pose with the car)

Wife should be satisfied for some time while I save up for a TT kit for when the new power she is experiencing wears off

I'm trying to read this and what I'm guessing is an increase in HP/TQ of:

Before After Difference
243 TQ 248 TQ +5 TQ
267 HP 289 HP +22 HP

Am I reading this right?

You are correct

vipor · 04-01-2010, 10:50 AM

And if you plan on going SC later?

You can always take the headers off and have it done at a later date, which is what I will do if I go SC at some point.

vipor · 04-01-2010, 10:55 AM

ah makes sense

Can you please post overlaid dyno sheets?

Hmm...those numbers seem a little low to me, considering (a) the mods you have, and (b) you used a hydraulic dyno, and those types of dynos are actually notorious for giving readings on the high side compared to normal roller-type dynos. It might have something to do with the pulls being done in 5th rather than 6th. I remember another member by the name of wstar went through the same issue. The problem, if I remember correctly, was that neither 5th nor 6th give a 1:1 gear ratio in the 7AT models. Never the less, you did get a nice gain, so congrats on that!

XwChriswX · 04-08-2010, 12:34 PM

When it comes to dyno's, can you explain why they are done in the manner they are, neither in the lowest or the highest gear, and why you dont step up through the gears? I never completely understood that...
