Finally had a chance to get Jim's E55 on the dyno. I have both Actual and SAE graphs. Blue line was how the car came to us, red is with VRP CF air box installed, as you can see the car is starving for air.

We are installing VRP 1 3/4 long tubes this week and starting on tuning.

Stay Tuned!

 

Needless to say, the VRP headers are no longer for sale!!

 

Awesome gain by just adding the airbox.

80mm I assume??

 

what else is on the car when it made that power? pulley, ecu, tb?

 

Vadim: How much do you charge for before/after Dyno? I may be installing Kleeman shorties and they are 'guaranteeing' 20hp to the wheels.

 

Hahahaha!! I was wondering about that!

 

Phatmitzu I think Jakpro1 has cams too

 

Oyyyy, too much.

Here's what was on it at the above dynos

Kleeman ECU Tune
Kleeman Headers, VRP new long tubes to replace them shortly
2.82 SL55 Diff with Kleemann TCU flash. E63 Half Shafts.
VRP Cams and Head port and polish (stock valves retained)
VRP 80mm TB
VRP Titanium Retainers for Valve Springs
EVOTECH 178?mm pulley, not fluid...solid.
EVOSPORT Plug Wires and Phenolic Spacers
K&N Filters
EVOSPORT Heat Exchanger with Johnson 90 pump running full time while car is on.

 

Dyno shop charges $125/hr., since there will be two separate sessions, it will be $250. I charge $100/hr., unless we are doing upgrade on the car with our parts.

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.

Jim has:

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..

 

serious power.. but serious budget too!

JackPro must be doing really well.. congrats on the beast!

 

Vadim, I believe JakPro1 has Stage 2 Heads.
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!!

 

Vadim, so that red line increase was only due to the addition of CF Air Box without any tuning yet?

 

Jim_ did you install the Bottom Mount intercooler?

Congrats on your new found power..

Now go install those VRP headers, get ready for the whiplash..

 

Vadim,

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..

 

23hp from the air box? wow that is great!

what was the A/F? do you have a chart?

 

Vic or anyone I had CF Airbox but Im over 8500 high elevations . Do you think how much power does my car gain with CF airbox ? BTW I had K2 , johnson pump, 160T- Stat.

 

no seriously how much is the airbox? i was under the belief that the carbon air boxes well at least Renntech's were only good for around 5 to 8 hp.

 

WOW bro, what the heck does your car feel like at that elevation?

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.

 

never got my car to the track before but I bet mine will run 13+ in 1/4 miles .Yes my next car will be either M5TT or E63 TT The S class is kind of big for me so Im stay with the mid size

 

1 3/4'' headers are next and than tuning.

 

cant see the dyno graph...?

 

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.

 

Wow..I cant wait to install my cams and dyno my car as well...


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 ???

 

so with my existing headers, pulley and 80 mm throttle body what range of hp increase might i expect?

 

Not to step on VRP's toes, but I imagine the gain would be pretty damn close to what Jakpro's car saw. You have basically the same mods minus only the cams and head work ...
