So my setup on my 11 auto gt premium is this-

Vortech v3 with stock 3.6 pulley jlt competition inlet on e85
Boundary OPG's
ported Boss manifold
Dynatech Longtubes and catless x-pipe kooks axle back
Circle D 5c converter
331 gears
BMR upper and lower control arms and panhard bar
Strange adjustable front struts
Tubular rad support and front sway bar delete
SVE drag MT ET street radial 295/55/15 rears 28x4.5 front runners
AED tune
3980 race weight
Car shifts at 7500 rpm

Best time so far is below hitting limiter on the 2-3 shift which has been corrected now but I have not been back to the track. My question is will adding the TQ booster and the 3.33 pulley get me into the 9's? Assume it would go 10.1-10.2 not hitting the limiter. Have gotten 1.46 60' but hit limiter in 1-2 and 2-3 shifts so I let out of it. Limiter is at 7750.



60' 1.514
330 4.297
1/8 ET 6.658
1/8 MPH 103.74
1/4 ET 10.394
1/4 MPH 131.25

cheaper to go 3.48 or 3.33 and call it a day.

v3 should make ~12 psi on the 3.33 which would be more than enough to get you there.

Thought 10 psi was the most these motors could safely take? RPM dictates what psi they make with each pulley too. I figured at 7500 rpm I'm probably making about 10 with the 3.6 pulley but the TQ booster would allow me to make it much sooner is my thoughts. I do daily the car in the summer months so not looking to blow the motor any time soon lol

youve got billet OPGs... guys have run 14 psi on stock 11-14 motors without issue. Obviously a risk everyone takes but ive seen 12 psi on mine PLENTY of times. My motor was 100% stock down to the oil pump.

Try the 3.48 if youre worried about it. Car would rip with that pulley.

Really? Did not know that.. I was under the impression 10 was the limit before your just asking for problems. I have a deal lined up on a used TQ booster for 350 is why I was interested in it. Figured coming into boost much sooner at launch rpm would get the 60' and ET down significantly. Also I think I'm at the limit for my fuel system setup with e85 and would probably need to do a return style which the money isn't there for at the moment, planning on that next year or 2 if need be. Whats your setup?

I'm surprised you didn't run a 9.x as it sits. I'd be very interested to see the gains from the Torque Booster setup as it will broaden the power band.

I wish it would have! lol but between hitting the limiter and a full tank, I think a 10.1X us very feasible the way it sits without the tq booster. My buddy us running a 14 with VMP blower off road X and twin 67 on the stock 85mm pulley VMP tune and went 11.1. There was also a 2015 there with a VMP stage 3 kit on the 82 pulley and twin 67 tb his best was 10.9 with octane booster so I felt like in comparison my car was running pretty good?

Yeah kinda surprised your already not in the 9s. Go 3.33 pulley for sure. I don't have the torque booster and i see about 13.5 psi up top. 1.51 60fts seem a little off for a 5C?

you should figure out why you're not closer to the 9's before adding more variables imho

you should be trapping 134-138 with that pulley

Lund has a stock converter stock drive train stock suspension on a 3.6" Paxton 2014 going faster @ 10.5@132 so something is definitely off

4000# race weight... you might be a mph or two low, but nothing to get bent out of shape about. there is more in the '60 as you stated. Get a good clean pass in and see where your at then maybe pulley it for 12psi and see what you get.

3.47 pulley will get you 12 psi. I would do the torque booster for sure with the 3.33 pulley.

Also, I wouldn't get bent out of shape with your times. A lot of cars are 4-500 lbs lighter than you running those times, 4-500 lbs would be 9's at 135+.

While I dont have a 5C, 4C here, it was one of the best mods I've done. It rips on the street with the torque booster package. Waiting for the tracks to open in order to get out there.

Sweet, I need to do this. Centrifugal leaves something to be desired from a dig.
