Default F.I./Stillen Before & After UpRev

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?

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!

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...

I must admit I was somewhat surprised also considering what Tony got on the LTH comparison runs from SpecialtyZ and also considering that the timing changes were kicked out by the ECM during the pulls with his customer. This tuner claimed that the timing changes (didn't reveal exactly what they were) he made were not kicked out. I asked him about the pulls in 5th and he said that 5th is closer to 1:1 than 6th or 7th which are essentially overdrive.
He was also really surprised at what the motor put out in 4th.

Oh shit?! I just realized yours is a 7AT also?!

AND your in Chandler! What's up! lol

Wow, those numbers hit closer to home now... Do you have any specific goal your trying to reach, or just as high as you can?

My understanding (and it could be wrong) is that you want to get as close to 1:1 for the TQ & HP readings to be truly 'real world' numbers. I'm sure someone more knowledgeable than me will be able to provide a better/more accurate explanation.

Where are you doing your runs at? Have you gone to any particular shops over there? Being in Chandler you must know of INTENSEMotorsports right? Those guys are awesome!

I wish there were more shops over here on the west side.

Someone else could probably explain better, but I'll give it a shot. The purpose of a dyno is to measure power output. Now, the 'cleanest' way to do that is to take the engine out of the car and mount it to an engine dyno. But that's not exactly practical, right? So most people just dyno at the wheels. Not only is it a tad more convenient than taking your engine out, but you're also measuring how much power you're putting to the ground, which many would argue is what counts anyway. So, that being said, you want to get a reading from the wheels while in a gear that provides a 1:1 ratio, because a gear ratio of 1:1 means that the engine and the transmission’s output are moving at the same speed. You want the engine and transmission to be in synch in order to get an accurate reading. Does this make sense at all? Like I said, I'm sure someone else can do a better job of explaining this.

LoL I must have made myself sound like a dumbass...

I understand the reason behind a dyno and what it does for you, what I'm asking is why do they pick 1 particular gear (obviously now for the 1:1 ratio thanks semtex! ) But I mean, does that give you the best Total output?

I'm just wondering for 'Practical' output... Say just like you would on a 1/4 mile, do a dyno thats actually going up through the gears just like you would in a race... Or would that be just completely retarded?

On the west side of what ? If you're talking about the west coast then you're crazy because there are a TON of badass shops there. Also if you're talking about AZ then there are still plenty there. They may not be Z only shops but there have been a few shops in AZ featured/mentioned in magazines such as Modified.

Yeah just West Valley... I live in Avondale, so like anywhere in Surprise or Goodyear, hell Glendale isn't too far of a drive.

Where are they at?
