342WHP / 347 Torque

Sorry for the pic quality, but my scanner isn't working.

Nice pull!

nice....how about throwing in 2 gals of 100 octane and reporting the change????

sunoco makes gt100 i'm sure you can find a distributor nearby.

i'm guessing +30-40 hp

nice dyno man, congrats. seems that stage II equivalents minus the headers runs consistently a bit over 400hp or so, and comparable torque - very strong! a good launch and that's a very quick car!

Really? 30 hp difference for that gas?

BTW - I got 310 the other day but the tech couldn't keep the car from shifting.

So how did you get the pull from 2400rpm to redline without it shifting? I did not think it could be done at WOT.

if 340/340 at the wheels holds true..

you are making more than 400hp.

very nice for a C32

most stage 1's are at 320 to 330 at the wheels..

Do you have a base line pull prior to the mods on the car. I'm curious how much you gained with the mods??

I don't think you will see anywhere near those gains with a little 100 octane. This isn't a turbocharged car. You'll still be running the same boost level. Your gains would have to come from ignition advance, and I don't think the ECU is going to give out that much.

Nice, that is pretty strong for the changes you have made. Do you have any other intermediate dynos?

Please do another after your headers so we can see the gain.

I notice you plane on getting the throttle booster. I wonder if you'll see any difference because you have a modified ECU. The ECU may already be doing what the throttle booster is intended to do.

I was in the car next to him and I think he slowly pressed the gas until the RPM's were at redline.

I made a video and when I get home I'll see if I can convert it to mpeg.

Thanks! I'm only missing the headers, so I'm close to stage II. I will be getting the Kleemann headers, as they are reporting up to 15% increase in HP. Link to Kleemann

Negative.

I'm kicking my own a$$ at this point.

Yes you WILL still see the difference, the Throttle booster does not change your computer settings it changes the rate the TPS measures your pedal input thus removing the lag created by DBW

this is a supercharged car whose intake air gets compressed creating heat which is indequately dissapated resulting in high IATs thus causing onset of pinging with protective spark retard bleeding off power.

2 fixes- increase car's capability to radiate IAT. or run more knock resistant fuel.

i run 100 octane on lapping days and it feels like a 20+ hp difference. i can kick the tail out easy with 100 octane whereas 93 need a deep stab at throttle.

on a stg 2 car the heat prob will only be worse. can someone go do a dyno run? i'm willing to bet the results will shock you.

everyone knows what happens on the 1st application of hard throttle right? car pulls nicely. immediate repeat applications yield a less than satisfying result. why? HEAT SOAK.

i hope to try VP racing motorsport 109 octane before end of year. i will have full stg 2, sl 55 intake (on already) and a custom front heat exchanger to replace the joke that is the c32's. i'm willing to bet over 450 hp.

You might change your mind when you see the cracked Kleeman header in the E55 forum.

I still don't get this change. Just step on the gas pedal harder or wear shoes that weigh 2 pounds. The TPS cannot be more than 100% so if you just floor it all the time, what difference will the booster make? I already have problems with traction, this would only make it worse. I can see it on a non modified car where traction isn't that bad but on a car with this type of horse power, going from 0 to 50 or 75% trottle pressure is just going to make the tires spin. Please help me understand this. Where is my logic wrong?

I orded 2 for my 2 cars..

I will let you know.

What i hate most of my C32, is that fact i don't get the kick down to 2nd when rolling around 40mph..

I get 4th and sometimes 3rd...

it takes a deep throttle application to hit 2nd.. (by that time its a bit too late)

I usually downshift anyway.. but I rather not do that. I car with 370hp should not need to downshift that much to get the power. ( i have pullies)

with the E55: I'm going to try it out. I don't really need it, but again the car does not have an immdiate punch when rolling.

From stop.. Yes.. big punch

on the freeway.. Yes big punch

but when rolling, again the transmission only kicks down a few gears and you don't get the right power (at around 3k rpms)

it would be nice.. if you can give enough input and get the response you want. I expect that from a 469hp 516 torque car.

My Nissan Armada 5.6 has a lighter pedal input and this things jumps off the line with the lightest touch. Its really easy to master after a few drives.

I want the same with the AMGs.

If this doesent answer your question then maybe you should contact Bulekos Dynamic... Essentially a DBW system does not have a 1to1 ratio between the pedal and throttlebody opening what this means is it reads the position of the pedal and tries to figure out what you want to do, do you ever notice you have to FLOOR your car to pass someone?..and i mean really floor and even then it sometimes doesent respond as quickly as you would like or find the correct gear. it does not mess or readjust your engine management, like a software change or "chip. It recalibrates the tps to read a more like a cable type throttle system which is a 1to1 ratio between the pedal and the throttle body. If you are not a believer try to find someone close to you who has one and you will see.

AMG-Jerry does not have one yet but he felt my car that does. Jerry what were your thoughts on how different my throttle response id to yours.

I hope I'm wrong, I really do. I tried straight 100 octane on my stage 2 car, and I didn't notice anything significant, so I really doubt that a 100/93 mix will do much, certainly not 30hp.
I'm doing a dyno run with 93 next week. I'll try one with 100 too, but it will be a bit later. I want to put in 100 then drive around for a while to make sure the car really takes full advantage of it.

On my last car (turbo), I noticed about 80hp gain on 100unlead vs 93, and around 190hp gain on C16 vs 93, but that was all gained by advancing the timing on my standalone ecu, and raising the boost from 20psi to 32psi. I did a pull on 100 ocatane using the 93 map, and I gained a few hp, but that was just because I wasn't seeing any detonation.

Nice pull Jerry

Per Cory at Kleemann as of Spring 2006 or so:

Boost Kit and ECU upgrade $3,395.00 (+40 HP, +45TQ)
Header systems $3600.00 (+30HP, +30TQ)
Camshafts $4100.00 (+15HP, +15TQ)

Just get the evosport headers.

Wow, that's expensive. I got my Shrick cams for $3600. HOP is making SS headers for the V6. They are going to be very nice. Should be done in a week I'm told, then we're going to test fit them on my car. I just bought the ASP pulley boost kit for about $900 too. IMO, the ECU can wait, just not worth it. Also got a Sprintbooster which I'll install tonight.
