Thanks. If the people at A&A corvette are that helpful, I will probably just look up their phone # and ask them next week. These 6klb grocery-getters are hell on drivetrains.

 

They are pretty good...

 

Is this being built in Southern California? I saw something like this just yesterday at a shop near by.

 

looks great mate!!

have you got any pics of the back of the blower on the engine?? be nice to see how you got the intake running forward. have you just made a box at the back of the blower??

thanks

Chris.

 

I will have pics taken from the back, the air box is where the stock is... Behind the blower is just the Throttle body adapter.

 

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....

oh you so need to make some videos of this bad boy

 

I will post more pics... not sure what kind of video I can shoot.

 

Glad to see you got it going. My friend's still hasn't quite got out of the 13's because of transmission issues. The third 4l80 arrived the other day, so we will see how this one holds up. I believe the best pass he got out of it was a 13.2 at SDR with all 4 wheels spinning out of the hole. The trans problems have kept us from bothering with the fuel system yet, so the 42# injectors are maxed at 6k rpm for now.

 

What is the car and weight?
How much HP?
what is breaking in the 4L80?
Where did you get the tranny?

 

wow....a lot to be taken outta tha bank to complete that build
hope you have patience

 

I edited my above post because it is actually the 3rd 4l80 that we are soon to install. This is the turboed Escalade I mentioned in previous posts. It has a Detroit speedworks (livernois) kit with a single gt67 and an '02+ls6 cam that was laying around the garage along with 42# injectors. The original 4l65 didn't have a chance. The second fully built 4l65 broke the output shaft. The first speed engineering 4l80 broke the output shaft (it was supposed to be a custom hardened shaft, but was really a turned down stock 4l80 shaft). The second 4l80 from performance automotive expired from unknown causes that led to slippage in OD while easy cruising on the interstate. BTW, they had kick-*** customer service and promptly shipped the replacement which is soon to go in. I don't have a clue what the actual torque and HP #'s are, because we only have a 2wd dyno.

 

wow man bad ***!

 

My first 4L80 from Speed Engineering was junked, used with burned parts in with about 200K miles on it. The torque converter was totally screwed up, the first block was honed out of round. I had my share of troubles.

I am very pelased with the 4L80 from RPM, TJ was most helpful. I took out the shift kit as it shifted way too hard. Lingenfelter has good luck with the 4L65s.

 

Very nice setup.I'm running the 4L80 conversion with a 5 disk 1800rpm stall.Feels like a stock converter which I love.I'll be surprised if those 60lb injectors can hold the fuel demand of 7-800rwhp in a 6500lb vehicle.My 60's have hit 90% on my small setup.

 

Sure it's made to go behind a stall, not a stock converter.

Awesome project, awesome setup.

 

Who did you get your converter from. I am still not happy with the converter. Even though its suppose to lock up in 3rd and 4th, even on freeway at 80mph, when I gas the car, the rpm goes up by 500 or so. It lockes, releases, just not consitant. Did not at all have this problem with the stock converter.

 

That might be a programming issue - worth checking.

Badass project - how do you like the Whipple 3.3 so far? I just got mine.

Jim

 

I also run a shift kit wit hthe built tranny.Was hard as hell in the biggining.I actually lowered the line pressure which helped alot.Shifts tight at part throttle and chirps all gears at WOT. The 4l80 tranny program leaves alot to be disired.Took me almost a month to get it where I like it.

 

Man, the intake charge temperature is freaking high on the thing. Other than that, make sure you get the correct tensioner setup.
