Are there any other options to increase throttle response for an 02' S Manual transmission?

I don't want to buy a Sprint Booster,, 350 just doesn't seem to make that much sense with no REAL performance gains.

Things that I think affect throttle response:
SC Pulley
Detroit Tuned bypass valve
CAI w/ UNI filter

But what else is there?

 

I believe that most of the custom ECU tunes improve the throttle response. A tune is more expense than a Sprint Booster but has many other benefits such as increased HP and Torque.

 

Forgot to mention , I do have a Mynes tune and my engine has been completely rebuilt by ABF Tech

But just I wanted to know if throttle response can be improved

 

Move your air filter right to the TB. Look up a very long thread on the so called "Hot Air Intake (HAI)" That was one of the supposed gains.

Add lightened flywheel to the list as well.

 

Crap forgot to mention I have an overall 17% pulley, 15% SC and a 2% Crank. I heard that the HAI heats up too much? Considering that it is right next to the intake horn

 

sounds like you have a lot of the go fast components, and a lot of money into it. The sprint booster seems to get consistent results, if you are at a loss, just go for it. 3 hundred bucks should be a flash in the pan.

 

You already have SC pulley, and both the DT bypass valve and CAI w UNI filter will do nothing.

You already have a tune....only thing left is a sprint booster or similar unit, there are some cheaper versions out there... they are a good mod IMO and worth the money

 

I have a HAI and really there isn't anything to heat up, just the filter. I constantly see 8-11F over ambient during cruising. No pipes, plastic...anything to "soak" heat. Personally I am happy with it. Keep in mind I have meth injection which can bring the temp down almost instantly and that can't hurt things. I don't have any experience with other setups though. My experience (with this setup) has been only positive.

Also, since the accessport was introduced to the community, there are new adjustments that are available to tuners. Without a doubt Jan adjusted the throttle for my Gen1. I have zero lag in my mind. If your tune is older, there may be ways Mynes has learned to do new things since the accessport intro.

 

push down harder? Isn't the only thing SprintBooster does is open throttle more with less pedal? Can't you do the same thing with your foot?

 

Tunes can be customized to your preferences. Ask Mynes to adjust your tune for more throttle response. Most tuners don't charge full price after the initial tune.

 

When you do a custom tune you can change throttle response. We do it with every tune we do.

 

Search for Sprint Booster, many threads. It is NOT the same as pushing down harder believe me, you cannot remove lag by pushing harder/quicker! I drive my 04 MCS JCW with the SB on Sport (not Race) setting. Sometimes I switch it off just to remind myself how crap the OEM throttle response is. Highly recommended, just do it! Expensive for what it is but not for what it does which is to transform the drive!

 

+1. I really hated the idea of spending $300+ to fix what I felt was a design flaw, but i'm glad I did. An R50 needs all the help it can get, and this helps me downshift smoother and faster, and accelerate quicker. Even if you are mashing the pedal down faster and harder, that first movement of the pedal is usless unless you alter it with the SB or a tune. Just go for it. If you don't like it, you can return it. I got a good price on mine through a group buy from Eurosport Design.

 

a tune can only adjust the throttle response so much before it starts throwing codes.... nothing like a sprint booster type unit....

 

I understand what everyone is saying about the sprintbooster but here's my question.

How in the world could the SB eliminate all the throttle lag we have? It isn't changing the throttle map built into the computer, simply changing the throttle map built into the pedal right?

If it's not the same as mashing the pedal then how does it work?

That's what baffles me.

 

I for one am against the Sprint Booster. My buddy had one installed and i HATED driving his car with one, and i did drive it often. I am guessing you are looking for REAL ways of improving engine response, and i think your best way at this point is a lightened flywheel. What clutch/flywheel set-up are you using currently ? The stock flywheel is something like 28lbs...

 

lightened flywheel provides very little improvment in throttle response IMO and are noisy....

 

Damn, I guess the only way is the Sprint Booster. That thing is too damn expensive. So i guess nevermind lol. I spoke to Hubie Fuh, since he tuned my car I asked him how he adjusted the throttle, and as stated D-Man stated, Hubie said the car will probably go Limp too. Oh well better $$ is spent elsewhere! For now I'll just press the gas pedal a little harder

 

Good question and probably best to go to the SB site for the best info.
Like a lot of things in my life I don't worry as much about how as if it works.

I got one with the idea it better work well or I would be sending it back in the 30 day return period.
I still have it almost two years later.
I know it does not add any power, but the response is somewhat like the difference between a 15% pulley and not.
Makes driving much more enjoyable.

Some people who have the first gen complained it was a little to much. I have the second gen with the two settings. The first is perfect and the second is a little much for me.

 

Here is a good read that someone wrote up regarding the Sprint Booster. Good reading.

In discussions regarding the Sprint Booster, it seems things get confused because people use the terms "throttle response" and "throttle delay" in different ways and sometimes interchangeably.

I would say that "throttle response" describes (a) throttle delay --the time lag between the pedal reaching some position and the opening of the throttle to some assigned position, and (b) the amount of throttle opening for a given pedal position (hence, the power one gets from the engine when the pedal is at that position).

The Sprint Booster does not affect (a), the throttle delay. It only affects (b); it increases the throttle opening for a given pedal position (up to a certain point only, which is about 75% of pedal travel. (After ~75%, stepping on the pedal more does not open the throttle more because it is already fully open.)

When people swear that the SB reduces "throttle delay", what they are really experiencing is more power "earlier" because they do not have to depress the pedal as much.

 

I've had the v2 SB and I love it. it has 3 settings stock mid sport and full on gas sometimes its a little crazy. my suggestion is maybe find someone in your area that will let you test it out. good luck!

 

Another for the Sprint Booster V2. I have seen them on sale "new" for as little as $299 US. and the installation is simple 10 - 15 minutes. Just follow the instructions.

Also remember that you have a 30 day full refund available. If you don't like it send it back.

Most negative posts I've read are from people that have never tried it or borrowed a friend's car.

I have not used the race setting but find the sport setting excellent for improving that initial lull in acceleration. I found that I adapted to the new sensitivity of the accelerator very quickly. Also, I find that in city or congested road conditions I simply shut it off!!!!!

 

SB is great. The V2 is even better as you can adjust it but it is limited to just two settings plus off.

What would be really cool would be to have one that worked like a gain *** on a stereo. Just dial in what works best .

Longboard

 

The SB 2 is one of the best additions I've made and I have some mods on my cars plus Jan tuned. It's a simple push of a button to remind me that it works and works really well on both cars. I've seen very few people who didn't like it and if you don't like it you can send it back within 30 days. I'd bet $$ that if you get it you'll be touting it to the doubters who've never tried one

 

I dont know for sure but i believe the VGS mod helps throttle response
