Sprint Booster with Dinan Stage 3?

With a NA motor I am always looking for more power short of taking the big plunge of a supercharger (but am looking at headers). I have Dinan Stage 3 software/CAI/TB and was wondering if anyone has tried the Sprint Booster now being offered by Bavarian Autosport and could tell me if it will be noticeable ($300) in combination with the Dinan stuff.

TIA,
Jim

Thank you for this help. Now I need to learn about the Shark Injector.

Thanks.
Okay, I just confirmed this with the Shark people. The AT is the kicker.
So, am I back to the Sprint Booster or is there something else better?

Having Dinan software should not have anything to do with installing the Sprint booster!



I have a lot of respect for Turner Motorsports, these guys know what they are doing and have proven it with multiple race wins and podium finishes. I was surprised to see TMS offering the Sprint booster on their website. If they are offering it and giving it a good review, there must be something to it! As they mention in their description, it can be used on both stock and modified BMW's!

If you purchase one PLEASE let me know how it is. I have the Dinan TB sitting in my garage waiting for install and will then be upgrading to stage 3.

Yes - a huge profit margin. Vendors like it because it's a simple to install plug and play part that seems to make a difference in how the car feels. But it simply remaps the throttle peddle. If you want a free sprint booster then floor it. There's a detailed explanation in the link from Post #2 above.

It did help some but I still have a lag when I press the throttle pedal. Several people have told me that the Dinan mods are very conservative and I have come to believe them.

Agreed that it does remap the throttle position but flooring the throttle now still has a lag (up to a second or more) before it responds. I am still pondering about buying it.

Ok I stand corrected - for autos it seems to eliminate the kickdown delay - if this is the easiest way to accomplish this, sounds good to me (not sure what the alternatives are). Here's the white paper on paraklas's web site: http://www.argyrides.eu/bmw/SprintBooster.pdf

Well, I have nothing against the sprint booster. It is just too much $$$ for what it does.

If it were cheaper, I might just tryi it out. But for $300 I can alot other upgrades.

Agreed - the price is just way too high for the little amount of electronics that are contained in the unit. This is why I have not bought it yet.

GREAT Article!! There is something to it.....you get full throttle response at half throttle! Slightly exaggerated but in essence the same thing! I wish each and every performance mod came with this kind of write-up!

I stand corrected!

Sprint Booster = $300! Press the pedal all the way = Priceless! Literally....

Remember when you try to go up ramps or make delicate moves in a tight parking space, you want half boost at full throttle.

Spring booster has its dangers when not used properly.

I have sprint booster kit for half off. $150 will get you this:
Throttle Position Accelerator:

Instructions.
Step 1: Take Throttle Position Accelerator and attach it to the drivers right foot with the Attachment Device.
Step 2: Have driver, drive car

This will not affect emissions or turn on the CEL. It works with all aftermarket software. Call now as quantities are limited.

once again mrshelley has outdone himself with a compelling product!

The only situation where I'd chose a sprint booster over that^ is in an automatic IF the sprint booster eliminated the kickdown delay.

However, because E46's seem to use a separate tactile switch under the pedal - rather than pedal position - to trigger kickdown I think the sprint booster is out of luck in changing that delay.

Unless someone can confirm otherwise I'm unreversing my sprint booster position.
