In my experience Kleemann does make 20RWHP, I have dynoed several cars before and after. They have a good product, the only caveat is that you have to move stock catalytic converters. A lot of clients do not like to have them touched for emissions reasons.
1. VRP cams
2. VRP Stage III heads
3. Kleemann shorty headers
4. Kleemann software
5. VRP 80 mm TB
6. Kleemann Pulleys
7. Stock Air Boxes with K&Ns
I believe that is it, but I am sure Jim will correct me..
Nevertheless he still has a long list of mods. Save some mods for the rest of us dude!
I'm not sure how well JakPro1 is doing TopGun32, but you can believe he's doing A Lot Better now that his car is finally on the dyno!! LOL!!

I am glad you thought about doing the CF airbox test.. I was going to mention it but figured we would end up doing the before/after on Jangy's car. Great idea!
Does everyone finally now see that the CF airbox makes power... that's 23rwhp and 38rwtq without any other changes!!!
Keep in mind that the more mods you have, the higher the gains will be..
Soooooo.... should I offer a special on VRP CF Airboxes now??
$2,400 shipped... lol..

I am at 4300ft and I thought MINE was doggy up here. I ran 12.5 at my local track with full K2 package with drag radials.
If you ever go with another car up there, go turbs. The TT V12's seem to do pretty well around here with the elevation. Chipped S600 runs 11.7's all day up here.
Well, that's Renntech ;-)
Seriously though, in all likelihood, as stated by Vic above, the gains are more significant on a car with additional airflow mods. In Jakpro's case, clearly he has a ton of other mods to increase airflow that were being choked off by the stock airbox. Opening up that restriction in his case allowed the other mods to operate closer to their full potential.
It would be nice to see the gains on an otherwise stock car, but there are only so many combinations of mods that these guys can test and document given limited time.

Yeah...probably this is why I cant do any rolling starts anymore in 1st gear...the car just keeps going side ways

What is the best AFRs for CF AB and air tubes around 12 as well ???
