Vengeance Racing VRx4, 90/90, m6, 12 bolt dyno inside All things considered I am pretty happy. Actually I couldnt post about this for a while. I had a grudge w/ a local kid who didnt even know I did the swap.
A quick run down of the mods.
Vengence Racing VRx4 Cam 228/230 .588/.592 112
Ported 90/90 by Vengence, Sanded and Painted
SLP Flow Pack (no smooth bellow)
SLP U/D pulley
Dynatech SuperMaxx Headers w/ emission w/ CATS
Corsa Cat back
Textralia oz-700 Z-grip
Moser 12 Bolt w/ 4.10's
3" Steel DS
Stock Heads, Waterpump, Rockers, Injectors, and Fuel Pump, Dyno Tuned.
A quick Run down on past dyno's
Stock w/ Lid, m6, 10 bolt:
324 RWHP @ 5,300 rpms
346.7 RWTQ @ 4,450 rpms
Lid, 12 bolt, DS, Headers, Cat back, bolt on dyno tune:
UN-Corrected:
1st pull: 336.6 RWHP @ 5,500 rpms;
5th pull: 350.6 RWHP @ 5,500 rpms;
1st pull: 355.0 RWTQ @ 4,500 rpms;
5th pull: 361.8 RWTQ @ 4,500 rpms;
Corrected:
1st pull: 326.8 RWHP @ 5,500 rpms;
5th pull: 339.9 RWHP @ 5,500 rpms;
1st pull: 344.7 RWTQ @ 4,500 rpms;
5th pull: 350.8 RWTQ @ 4,500 rpms;
Cam/Intake/UD pulley Swap:
396 RWHP @ 6,200
375 RWTQ @ 4,500
TQ was over 350 @ 3,500
This was with a retune which didnt do much over the bolt on tune, minor clean up. Dirty air filter and fuel filter and heavier drive line
Had it been a stocker drive line, it wouldnt be un reasonable that it would 412-415 rwhp on a MILD cam that drives like stock, and has a nice, exotic sound w/ the cat back.
Since I've gotten over Cancer, now I will get a chance to make it to the track. The thing weighs with me just short of 3900lbs. I dont expect 11's but 12.20's isnt out of the question.
As for the ported 90, I am sure it helped a little but when paired with ported heads it should do 430-440 rwhp, maybe 5.3L 225cc or Ported LS6, I havent decided.
Oh and with the kid who I was keeping this from, he made 405 RWHP with a similar (maybe a lil smaller cam and ported Patriot LS6 heads), At the peak he edged me but below 5.5k I owned him in the power dept.

Nice numbers man Congrats.
The old numbers were with or without 12bolt and Driveshaft???
Do you know what is the duty cycle with stock injectors??? they must be maxed out I think with Fule pump and 30+lbs injectors maybe you can add more timing????

Only the 1st set of dyno didnt have the 12 bolt, the next 2 are with.
I will have to check with the tuner, they didnt mention anything but I havent personally logged data. The A/F was dead nuts on.
If I hook up a n2o kit, its going to get an upgrade on both.

BUt then again, the fuel system maybe maxed. I will check into that.
Also if the converter was locked in the a4 car, then who cares, its not locked when he runs the 1/4. If this person your refering to has the same mods and doing that unlocked, then thats about the highest dynoing a4 cam only car ive ever seen,

Had the car been a 10 bolt/ stock DS It would have been about low 400's, on a 228/230 cam, not bad in my book.

Cam is a 230/230 .609/.592 111+2 LSA
You should get a bit more out of yours, your cam is a XE-R/XE grind.
look at fuel, tuning and MAF areas

I can certainly have the fuel checked, and maybe adjust the tune but its pretty spot on and the car didnt want to take any more timing. As for the MAF, it doesnt matter at WOT, unless physically its a restriction.
There are thousands, upon thousands of Cam only motors w/ different setups and situations, not everything is comparible.
I personally beleive the ported 90 didnt do much over a LS6 intake but I did it now instead of later and finding out no one wants to port it.

Thats a nice ET but expected with a automatic with a properly set up driveline and tire/suspenion combo.

First fix your fuel by getting the right fuel pressure at WOT without that drop the stockers are known for, that requires a FPR at the rail. a ported 90 should give you at least 15 rwhp, otherwise you waisted you money, which is not the case, they usualy show 20+
85mm Maf will make a difference. You have a good20whp missing, because of your fuel and Maf

What was your injector cycle? and putting a 90 at the back of a 75mm Maf is choking the air inlet.

From what Ive read I would need a 85mm lid and MAF, Fast Toys sells them. We will have to see. Also get some green top injectors and a racetronix pump with a hotwire kit.
Then get the tune adjusted.
In theroy the larger inlet should make the difference.

He was advised to get a MAF before the install, but everyone around these parts seems to think that non stock MAF sensors are the worst thing for your car other than just pouring gas on the car and dropping a match.
