Installed the Sprint booster v3 today. Started out on green 1 and worked my way up to #9 . Didn't feel any different to me. Put it on Red 1...nothing really. Jumped up to red 5 and I immediately felt the difference. Worked my way up to #9 ..what a difference. Feels like I have the bigger throttle body back on again!
...The video where buddy picks up 3/10ths from 0-60 is quite believable now. There is no way that this is " not " making the car quicker. Throttle response as folks have mentioned is instantaneous...quite awesome. What a perfect combination with 3.91 gearing. These 2 changes turn this car imo from " mild to wild". Feels like the engine has been opened up and worked over. Add a CBE.. test pipes , injen sri...and this little 3.8 sounds mean and works how it sounds. I have it set on Race 9...and that's where its staying...lol

It feels like my coupe has been tuned with the Sprint installed. This and the gear change make it very hard to do the speed limit..lol

Now add 3p8 Manifold Risers for A massive combo attack and massive gain on mid rpm (sprint booster give you faster TB and faster launching and riser will give more more power in the 3~5k RPM, its the ultimate cheap combo mods for the Genny)

And yes, i have the Tros Boosters on FA9 (most aggressive option like the Rcae 9 on the SB) and itís insane.

They are proved with dyno charts and there are some youtube video about them, combo the thing with the boosters/sprinter will give you best result that you actually feel on the cheap (also safe for the engine and easy to install) for sure.

Added some Eibach lowering springs a few weeks ago. A sprint booster a few days ago. Bilstein shocks this week. My union just got a contract signed so I have a green light to use the funds I had put aside in case of a strike.
...Rims and tires next week. Then a manifold riser, engine leash, lighter crank pulley and ported throttle body.&#x1f60a;&#x1f60a;

Did my own sprint booster testing today on my favorite on ramp that I frequent regularly. With stock 3.55 gearing I could reach 62 mph before braking for a corner. Gearing change to 3.91..speedo corrected...72 mph. Sprint set on race 5..speedo corrected ..77 mph.

Not sure if you are M/T.... But if you are then the Megan trans mount (pretty simple install) and the 3point8performance engine leash will tie in perfect with the throttle controller.

Then a custom tune to top it off. Dont even need to go for power, just good and safe tune and drivability with the tune and you will feel even better about how it runs &#x1f609;
