Just installed the code3 intake and pulley, reset my ecu and went for a spin.
I took it easy at first but couldn't resist pushing the pedal. The car took off like crazy. The only downside is I wish the pedal was linear with power delivery and see that's where the sprintbooster can come in handy.

On Victor's advice, I got the Sprintbooster, easy install and it works! I have the same mods as you (plus LET's ECM), so it should work for you and make it feel "peppy."

Or you can pay twice as much for an ecu and get real results

the sprintbooster's worth doing just for the buzz it gives you

I took mine of recently because I was having throttle issues,

this was after it being on the car for nearly 2 years and my having gotten so used to it that I didn't really notice the difference it made.

after I took it of, the car felt like a slug but I made a point of keeping it off till I got everything fixed and my LET pulley installed, then after a couple of days getting used to the car again I put it back on and went for spin, as soon as I set off I was like and had to readjust my driving technique yet again.

I would suggest periodically removing it for a short time just to so you can appreciate how much more fun the car is with it fitted

Looks like it's $299 everywhere......

Thanks.

actually the sprintbooster will make the car more jerky in first gear, if you don't feather the throttle correctly..

also.. your MPG will drop about 1 or 2 miles across the board...

Believe it or not.. just adding the C3P filter and no pulley will help with throttle response and will not be as aggressive as a Sprint Booster..

However Sprintbooster does have 2 models.. regular and AMG.

regular means.. its more aggressive.

AMG means.. less aggressive.

in my case... I had a regular for about 1 year with Evosport pullies. Back then.. the AMG was not sold yet.

I can only relate to the regular sprint booster.

If you are going to spend $299 on a gadget.. with no performance gain..

probably best to spend on the air filter and increase boost and response and gain power.

jturkel

yes, and in case anyone is curious as to which is which when ordering, i happened to have the box nearby. the AMG one is 451A. I think this is opposed to 451 B, which is the regular one (not for AMGs b/c too aggressive)

I thought the AMG Sprintbooster was BDD451A2? Thats what I have....works great.

jturkel

hmm...i was told otherwise. minesays: "BDD 451A." this is probably resolved on one of the plethora of threads regarding this product.

timberman

mines BDD451A as well

I always thought the A referred to automatic

mdncn2762

It Is

BDD451A2 is the correct model for our autos.

You do know that our throttle response STOCK is linear. The Sprint booster turns it into a reverse exponetial function, ie a little pedal travel, equates to a large throttle body opening. Oh well, food for thought my friend.

See yeah

Interesting...

Others have stated (smart folks on here, who tend to know what they're talking about) that the Sprintbooster simply amplifies the throttle pedal signal 1.3x - so it's still linear, but you reach max throttle with about 30% of the physical pedal travel remaining.

MRAMG1

I am buy far NO expert on the Sprint booster, but I too have been informed by MANY very knowelgable people on the subject. In any case, it simply exgarates the signal, ie opening the throttle body quicker. With that in mind, and me road racing a bit, I personaly would not enjoy it. I like to regulate the pedal with my foot/feel. Anyway, check around, I am curious if my info is right. In any case it will give you the perception that your car is quicker, simply by giving you more throttle during the first half of the pedal travel. It will NOT give you any more REAL power. Let me know what you find my friend.

See yeah

No matter the opinions of others I will be more then happy to spend $300 on a devise that only creates a better sensation...even on a modded car it will still show its worth. I have read that getting the ECU tuned does the same well with the pulley and ECU tune when I removed it for a day it was sluggish as timberman's car reacted and once back on it felt like a champion again.
Maybe at the track removing may result in better times due to less aggressive wheel spin...I will try to find out July 19th.

The one thing I have noticed is Road Racer and autocrosser do not like the Sprint booster. I would imagine it's because you have to get used to two different types of pedal feel. The sprint booster is really noticeable from a stop, but while your foot is already on the gas and you're just giving moe, not so much. For drag racing and spirited driving it is much appreciated. For the other types of racing I can see where it would be of a nuisance then anything.

edtv82

i've had mine for about 10months or so.. i've taken it off put it back on several times and the only thing i notice more is i get heat soak a lot quicker if im not doing Highway/Freeway driving... in the city it can blow b/c of all the stop and go... but anyway. it still a nice "speed racer toy" to have.

Fifth Ring

I just press the gas pedal 1.3X faster for the same result.

MRAMG1

+1 My friend



See yeah

Actually, this is the way I've decided to go. I can always add it later if I really want it. ECU should be done in a week and saving up for suspension. After that, I'm just going to enjoy it more. I'm spent OUT. With motorcycles to care for, money is thin right now.......

My wife hates to ride with me because I've mastered the 1.5x "manual" sprintbooster, even in her minivan.
