Well Project is finally done, after 7 months. I will post some pictures soon. Running the Whipple at 12 psi and 12deg of timing until the engine breaks in. Then will go up to 15 psi and 9deg. Will have Meth injection from Snow Perf. installed with an on-demand switch for days when its over 100deg which we get it socal in summer time.
The car hauls A** and the 4L80 is much much better. Had to go through two trannys and two Torque converters. The first tranny, I was chated and felt like a sucker. It was an old standard 4L80 sold to me by speed Engineering. He had sourced it form somwhere else. Cost me $5K, had about 200K miles on it and the wrong output shaft. The first torque converter from RPM Transmissions with 3 clutches, had too high of a stall, 2400. I hate stall converters. So had another one built with 1800 stall and 5 clutches I must admit, I like stock factory converters better, but they are not strong enoung.
The new 4L80 from RPM is MUCH MUCH better. I am happy with it now, but do miss the taller 4L65 4th gear. I may go down to 342 rear from 373s, just need to lower the RPM on the freeway. Turning 2500RPM at 75mph. Its about 500RPM higher than the 4L65.
The 4L80 needs more cooling than the 4L65, but the torque converter has a lot to do it. So two B&M external coolers are ordered. Still need to come up with a cold air intake and swap the battery location.
I must say Andy at A & A Corvette, is an amazing guy. This man knows what he is doing. He is not done until its done right.
I have not floored the car yet. But just getting on it softly here and there and while cruizing is more than even my Eibach suspension can handle. I thought I had enough suspension, but for this much power, I will need more, hope I can find something adjustable.
running 60lb injectors, and the oil presssure is 60psi. The Ron Davis Radiator with a 160 thermostat keeps things pretty cool for the motor which helps keep detonation at bay.
Gas mileage dropped from 14MPG to 10MPG. The motor is now 1000cc bigger, and the tranny has more parasitic loss (4L80) and the 3.3L whipple takes more HP than the 1.8L Magnuson.
By the way I will have the other torque converter for sale. LS7 to 4L80 $600, paid $1000, drove for 5 miles
Will update you with pictures....
