I'm getting ready to order sprint booster for the 6 and wondering if anyone has installed the newer SELECTABLE version on their 6, and would care to share their thoughts. I've searched here and know that others are interested in the selectable,but didn't see any that have gotten it yet. I don't want to get it until any bugs are ironed out. I thought it would be great for my wife and I, as we both drive it on occasion (it's not a daily driver for either of us) and she feels it's plenty powerful and responsive already. So if the sport/race mode freaks her out, it's a simple push of the button. I look forward to quicker response for sure! Also wondering if the selected mode stays the same for the next driver or does it default to stock each time the key is turned off? Bob

 

Hi Bob,
I have insalled this on my SRT6, it is fantastic, there is quite a difference in response between three settings. I generally drive in "Sports Mode", more responsive than stock but still smooth, Race mode is so responsive it is not nearly as smooth, but great fun when out for a play.
As for your question, It stays on the selected setting until you change it.

 

I have a sprint booster and the three level velocity booster that throws codes and limp modes.

Can you give me more info on the three level sprint booster?? That one is new to me, thanks Woody

Nisteel beat me to it w/ the link there Woody. His review makes me want to go ahead and order; yours does not. But aren't you the one that did a homeshop version (I think I remember an older thread about that). If this was you, I know you're one of the Guru Masters here and I mean no disrespect Woody; I share the same nickname as you so go easy on me please. Hopefully the R&D engineers @ sprint booster (Boulekos Dynamic?) have this thing figured out. I look forward to your thoughts, and will wait to order this until then. Bob Attwood

 

I had the sprint booster early on and liked it, the velocity b has issues on my car and throws codes if on or switched off and showed no gains over the sb.

Iam so unhappy that Iam going to build a throttle body driver or current mirror to get some real speed in the TB. It is slow and .4 decreasing to .3 seconds is no gain in my book. I really have grown to hate the fly by wire and would avoid it if given the option. I have 6 cyclinder Ford vans that have better response. YOU can believe that I have considered the cable addition to overcome the terrible delays that we have.

Autocrossing is tough because you have to anticipate the throttle going into turns so you can lead the damn computer. To the designers, off with their heads............

 

I was going to purchase one of the selectable SBs but if you are going to fabricate something, maybe I will hold off

Keep us posted, please.

 

This is really the only thing I can't stand about the 6. Please solve this problem, this would transform the car. The motor feels so disconnected....

 

Do you keep it in "D" most of the time?

 

Thank you Nisteel for sharing your experience w/ the new selectable. So..... the race mode feels just like the old fashioned cable to butterfly? Bob

 

So.... should I take your response to mean that you don't feel the newer selectable sb could be the answer to our prayers? Maybe the newer selectable sb in the race mode is just what we're all looking for. I'm going to give it a whirl. But I think you competitive racers would be the better critics, (I use to be competitive; just can't afford it anymore) I think they have a money back guarantee. I will report my results. Bob

 

Hi Bob, yes in the "Race" mode there is no throttle delay at all, it is nice though to be able to select a smoother response for day to day driving.

 

Hey, I have a quick question. If you have your car tuned, can't they fix the same issues a sprint booster fixes when they are tuning it? If so, how much is it to have a sprint booster installed vs a tune? If not, what is the gains to be had above flashing?

 

Yes, my commute has lots of traffic. I'm going to wait and see if Waldig comes up with something, if not I'll buy the new SB.

 

From what I undersatand, they are completely different. A tune can really wake up the motor by changing things such as timing, air/fuel mix ratios, RPM limiters, top speed limiters, etc. But to the best of my knowledge, it is completely independent of the throttle by wire system that the SB affects. It literally plugs in right behind the pedal in line with the throttle wiring....

 

I couldn't agree more w/ this statement! I am completely satisfied with the new SSB (selectable sprint booster). I thought for sure that I would want the Race mode (red light)all the time, but the sport mode(green light) has better drivability(yet plenty quick)for daily driving. My wife loves the new response in sport mode and thought I "chipped it" until I explained to her about throttle by wire. The Race mode does freak her out though, and I always remember to leave it in sport mode after I'm done playing. I found the little selecter button lights were a little bright for my taste, so I mounted it up directly under the steering column. Out of sight, but within reach. At night it is a nice dim green glow(or red,if your out speeding about) for the pedal area. Yes, it was a little pricey @ $329. but would say for certain that it's a good bang for the buck. I know that a lot of Forum members have the older SB's and know there were (2) models, (1) was too aggressive for some. They must have just put the 2 into 1 and gave us a light button to switch between the modes. I'm enjoying it. The only negative I have was having to contort top half of body down into the pedal area. If I had to do it again(and for us old guys)I would just remove the drivers seat and eliminate a lot of frustration! And I found that a pair of standard tweezers spread open(couldn't find my magnet) worked perfect to pull the washer up & out from pedal stud after removing the 10mm nut. Sorry for long post. Bob

 

John is correct...you can't tune out the lag...go SB....the one in the roadster must be in sport mode, 'cause the one in the coupe is in race mode...lol

 

Thanks for the review!

 

I have been doing work on a design that will replace the current system so that the response will be at least a 100% FASTER. THat will be 1/2 the delay we currently have to deal with and there should be a smooth / small power gain across the power band.

This is not going to get legs until the autocross season is over cause I gotta get it all apart to do the testing, there will be another article soon about testing to show you what makes my tick or at least gets my creative juices flowing.

Autocrossing brings out the intensity of the throttle delay. My autox experiences brought about the design need for my supercooler, dual inlet CAI and oil separator cause I needed them for high rev operation and high loading driving.

I have tried the sprint booster ( a winner for me) and the velocity booster that is yet to work for me ( throws codes all the time even with the control set to off. My design goals are 100% GAIN IN THROTTLE SPEED, thats 1/2 the delay and a bit of power gain across the full rpm spectrum. This approach will not affect your girl friends ability to drive to the store, It will allow FULL POWER and response and with a flip of the switch NORMAL operation. Trust me yull love it and IF it turns out to be a real good idea, Rob {Needswings}will be doing his part to make it plug and play, yippie.

Warning Warning Will Robingson this development will not start in ernest until the autocross season ends cause I gotta take the car apart to develop the mechanical parts and make it all fit.

To see the impetus that drives me as it were, tune into the utube to see the autocross a while back in the wet. Not the throttle response when it pulls the rear tires loose on the pavement. ENJOY< Woody
