[QUOTE="1Kona_Venom, post: 13640598, member: 101429"] After a lot of contemplating and discussions I switched out my 2.9 Whipple for a TVS. Most of the data is probably already known by most, but the biggest take away here is if you’re just going to run pump gas, 93 Octane, and primarily hit the streets, than this might work for you. I’m just an average “JOE” with pump gas comparisons.Took my car up to Bob Kurgan and what I rec’d back was NIGHT and DAY difference. I have completed my winter project early. For me, dreams of a bigger motor and E85 kind of came to end after the shenanigans with the Swamp Whore known as, IronHand Racing aka Cory Kolk. And also retirement from the Army came faster for me so my budget is not nearly what it use to be. I could have gotten the TVS w/ GT500 throttle body but decided to save the cash difference (about $1000.00) and go with the Accufab TB inlet and reuse my existing throttle body. (The money I saved could be used for custom cams,headers,etc someday) I run 93 (with a little Torco to be safe), so that netted me 19#’s on the 2.9 and 20#’s on the TVS. If you want a “seat of the pants” comparison…..the TVS, as all have said, comes on IMMEDIATLEY as soon as the sole of the shoe meets the gas pedal. With the 2.9 @ 19#’s (mid to upper RPMS) of boost, the blower lags. BIGGER IS NOT ALWAYS BETTER! My wife’s Comp Orange has a 2.3 Whipple @21#’s, so I have felt firsthand the “seat of the pants” comparison between all three blowers . Here is my setup: TVS/2.8 pulley/Accufab TB Stock Lower stock manifolds, o/r Xpipe, LM2 Catback JLT HB Intake Sct3000 Lethal Return Fuel System 80# Inj. Spec3+ clutch Setup was the same except with the 2.9 I ran a JLT RAM AIR CAI All runs on a DynoJet. Same tuner…Mr Kurgan (thanks again:thumbsup:) Car runs and idles just like stock. We also tuned the car with the 2.6 pulley and race fuel. 2.9 Whipple vs 2.3 TVS Dyno Graph~ Power the same gained TQ with the TVS [ATTACH=full]522111[/ATTACH] [ATTACH=full]522112[/ATTACH] Pretty happy at this point, car is a blast to drive :beer: [/QUOTE]
