At this time, I will happily say that we have basically completed Project CLS! Most will agree, that you are never fully done when modding

This vehicle has had quite the journey, as the build has taken roughly 2 years from start to finish.

We started with a brand new stock 2007 CLS 63, have gone through 2 sets of headers, endless ecu tunes, dyno tuning and now end with a 722hp nitrous filled show car!!!!

Mods List:
Engine
RENNtech Custom tuned 91 octane file, and 100 octane file
RENNtech ECU Block (allows data logging and code reading)
ACG Long tube headers (will fit both E and CLS63's)
ACG 100 shot Nitrous Kit with safely switches (Wide band, fuel pressure, throttle position, and RPM rampping)
RENNtech Rear Mufflers
MPH 180 degree T-Stat
Cooling spacers
RENNtech Airbox (Coming next week)

Wheels/Brakes/Suspension:
20" Vellano VSE Brushed/Chrome (Show Wheels)
18" HRE C21 Black/High Polished (Track Wheels)
Brembo 8 piston Front BBK
Brembo 4 piston Rear BBK
RENNtech Toe Links
RENNtech Lowering Module
Quaife LSD


My apologizes for the lack of information right now, We're just so excited about the numbers that we hit!

Dyno sheets will get posted tomorrow, and we'll even get a dyno jet number for comparison reasons!

I'll post pictures and more specs later today or tomorrow, as the other half is complaining about dinner.

Pics please!

James,
That list of mods took 2 years? and with the mods in the list you are getting 722 HP.
Please tell us the rest........

LZH

Look you doorstop noob....he did say these were early results and more info would be forthcoming. And as this is the de facto forum for mods, it IS the correct place to post. Perhaps you should just say "congrats" and leave it at that. What do you drive anyway ??

Cograts James - very impressive numbers. Did you guys dyno the car without the juice ??

J 2OOI

Please do 1/4 mile runs as well. I find those results much more telling than dyno #'s. Thanks and goodluck.

James@ACG

Off the juice, we got 597hp on the 20's

James@ACG

We hit 11.6 on a 91 tune before the long tubes and custom tune....

honestly I'm hoping for high 11.4x hopefully better

mthis

what is it dynoing to the wheel congrat thats sick 722 wow whos car is it anyone from here?

James@ACG

We'll in the middle, we the VRP s/c project not work out, and the andy at MHP delay.

RENNtech Exhaust Installed

Month 8
VRP S/C Started

Month 10
Vehicle runs 12.38 in the 1/4 mile

Month 13
VRP S/C Project scrapped

Month 15-20
MHP Tune experimented

Month 18
ACG Nitrous Installed
MHP tune (Was tuned to Stock
Vehicle runs 12.04 in the 1/4 mile off the nitrous
Vehicle runs 11.75 in the 1/4 on the nitrous

Month 19
EVOsport UD Pulley Installed
ACG Nitrous tuned with RENNtech ECU Upgrade
Vehicle runs 11.97 off the bottle
Vehicle runs 11.68 on the bottle

Month 23

Special Custom Tuned RENNtech ECU Upgrade
dynoed at 722hp on the bottle, and 597 off the bottle

Hope that helps

James@ACG

We will put it on a dynojet this week to get actual wheel numbers, the load bearing dyno that we used to tune only provides crank numbers.

Wow those are some crazy #'s for a 63! Congrats!!


Awesome numbers! Can't wait to see it on the track!

Congrat was all you needed to say


James keep up the great work

Ali_E55

not interested in Nitrous.

i don't feel it is a true power with it.

SLR engine can reach 750 without it.

The car has so much TQ that a TQ strap is being made and installed to keep the motor mount from ripping again High 500's tq N/A & over 650 tq on the juice As of the last HP #'s just over 600 N/A also might add that so far all dyno pulls have been done on very hot days The car is scary fast and the tq #'s are very very high even at the 2000-2500 rpm. These headers are FANTASTIC A BIG THANKS to James and crew at ACG for all to long hours, days, months and years to get this car on the map. AND YES WE WILL BE AT THE TRACK

rarfinancial

If you had any Idea how or what it takes to get the 63 motor to these #'s even with nitrous you may see this thread a little different.. This thread is not about what you think about nitrous but it is about a CLS63 reaching 722hp and about ACG's CLS PROJECT Sorry for the vent but

722hp & 650tq on a fresh tune & a hot day?

hooleyboy

If you are racing here in AZ expect a DA of 3000-4000ft. With an NA car its a heart breaker. The tracks are just not fast out here this time of year. Do a really really hot long burnout if you want a chance at hooking up. Hope you kick some butt out there.

juicee63

Rick you hitting Speedworld Saturday night? Can I come. Maybe my car is finally FIXED BY FRIDAY! oy vey

rarfinancial

Speedword? Ya man lets do it I know it's not good racing weather but racing is racing... Anyone else care to join? it hould be fun... I'll call you in the morning..

hooleyboy

My car is in the shop getting our long tubes made right now. No racing for me If you want to grab Beers I'm always down for that. I can get Ken to come out too.

Congrats! Those are some killer numbers fer the 63! Look forward to wheel numbers!

VCA_AMG

And yes those are impressive numbers, but we're dyin' for photos here brah.

DAGREEKNYC

those are crank #s i take it ?????????????????????

Ali_E55

if u want some brag about 63 engines, i know someone who did bi-turbos for it and it reached 810hp ^_^, but the Tq were limited because the gearbot can't handle that much unlike the 5 speed one.

so, to talk about reaching high numbers, it is not the big of a deal. lo0ol

regards my friend for your acheivement.

if you wan information about the 63 turbo, i can get it for you, but believe me. it is hard to drive it in a line with that power @@

Mantooth

There are a lot of 'one-uppers' in this thread, lol.

Congrats on the build! Siiiick numbers for an E63! I can't wait to see some vids at the track.
