Well, I have an addiction for power and my 2004 supercharged ESV was not enough, it had about 500HP. Spoke to the guys at Lingenfelter and they promised me they will deliver over 700HP and 740ft-lbs Can't wait. The best part, the wife does not even know he he he she would never let me do it, so I am dorp shipping it there...

Sounds great, what are they going to do about the trans? I have several customers with supercharged engines, they are all on their 2nd and 3rd transmissions. :(

Sure will do... I have had no problems with my trans at all. I have had the supercharger after 300 miles was on the car along with a complete exhaust system and brake system. I tow with the car and pull 2000lbs with it all the time. No issues so far. If you are gonna get on it which I do aaaaalllllllll the time, you should put it in the Trailering mode.

As for the Lingenfelter setup, they have some other upgrade that they are going to do the tranny. They will put in a 7.0L aluminum block with a twin turbo setup which will be nice becuase the supercharger is noisy, something I never liked.

They will have to replace the tranny w/ a built 4l80E. A 4l65 can only be fully race built to handle 600hp, and even then they usually fail- expecially under so much weight. I was pushing 600+ hp in my '03 avalanche with a built 4l60 (65 specs) and the tranny was crying after a few months. I've seen the TT EXT and it is bad!!!! Good luck sounds great...

Trailer mode just changes shift points and keeps the convertor from locking in and out, does not help with the fact that the trans used in the Esclalade's are the weak link. :(

Well Gents, I am having major 2nd thoughts... Wonder if I did a spare of the moment move... I can get to about the same power level it seems with no more than $15K. Just by getting a long block built based on the same block with a stroker crank that makes it a 408 with with .030 over bore and other hardware to go along with it... what am I missing !?!?! I am starting to get feeling that I am paying for a brand name, might have to pull the plug on this on the exisitng path...

aarrrghh

Can you please give me some more detail about the tranny? Actually a lot more detail :worship: Is what is on the ESV a 4|65? and what is a 4|80E

57K for 700 hp? Ouch!
You can take that same motor, buy a better set of heads (or have yours ported), fool with the EFI and get 700 HP easy!
My race car has 1100 HP (no nitrous) and that motor was half that price.

Yes I know and I am seriously thinking about backing out of this deal... A guy is telling me he will make me a 408cuin long block and tune it with the existing tiny supercharger and get the same kind of power. I think they are asking more because of their name...

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....

Yes I know it tool so long. But I ended up dropping the car off finally on July 14th. MAny problems on the way. Bad tranny, bad torque converter, bad Engine block.... all these cost time and money.
