Can someone please give me their impressions of this kit. I am going to schedule soon and would like some opinions.

Thanks,

I would like some info as well, maybe a dyno?

thanks

Just got mine back. Idle sounds awsome. It is an A4, I choose to put in the aggressive cam. Don't have the specs but can get them. Definetily lumpy. Have not driven the car yet, I have a back injury that won't allow me to drive it for another 2 weeks. Dyno sheets of the before and after look good. I dropped it off with bolt ons and it made 326.5 hp & 346.5 tq. The torque converter was not locked. They do all the A4's unlocked. After everything was done it makes 418 hp & 370 tq. If you have a manual you'll get much higher #'s, damn auto!

 

Please post a graph and cam size. Are you sure the TC was unlocked?

 

My brother's '99 FRC is scheduled to go into LPE's shop next week, to have that package installed. He should have it back around the first week of May. You might want to check with him; he spends a lot of time in the C5 General Discussion Forum and his sig is Red Vamp.

 

Had mine done at 21CMC in Texas 2 years ago. No problems or issues at all. 97 with bolt on made 318 rwhp, after H/C 400 rwhp. Car definitly much more fun to drive.

 

I got the package back about 3 weeks ago. I kept the Ls1 heads to save money, otherwise exact same package. They proposed 475-480 horsepower. They delivered! Are you having the Yank 2800 put in also? My car is AWESOME. It hauls butt like you wouldn't believe!

 

I have the dyno sheets, I need to get them scanned and then someone could post them. I have never attached sheets or pics before. Help me out. As far as the TQ being unlocked, unless it says it on the sheet somewhere I'm going based off of what LPE has said how they dyno'd the car. I specifically asked this question because I thought I may have been able to get more power from the package. Again I have yet to drive the car so I can't speak as to what my satisfaction will be but it sure sounds awsome at idle.

 

Wait till you drive it!!! It's like you won't be driving the same car. Especially at WOT! Hold on tight, and be careful. Mine will get rubber big time from a 40 mph roll with traction control ON!!!

 

what does something like this cost?

 

$6,500 according to http://www.lingenfelter.com/pack_cor_c5_350500.htm

are they quoting rwhp or fly? pricey!!!!

 

They are quoting flywheel. And from the results I have seen posted on this board, they are short of the 500 fwhp and WAY DOWN ON TQ. You could do a bunch better with the same money.

 

No, it's not really pricey. I thought so too but then I started building a spreadsheet on all the things I wanted to do to mine. After I was finished, my parts alone were right about the same amount. I figure you're getting the intenal work, the assembly and the installs, by the best in the business, for free.

I'll have to wait awhile to get it done, but instead of me doing the work and building it up with nickles and dimes, I'm going to the people that have the reputation for being the best.

 

I'm curious how you came up with a parts list that exceed $6,500. Off the top off my head the parts listed in the above URL are under $3,500. Also, that price is for Z06 cars (meaning that it would be more expensive for non Z06 cars because of the head costs).

Because I wasn't using the same parts. I had AR heads, a FAST intake, a 90mm throttle body, etc.

Now you might argue that the reason my cost was higher was because of better stuff, but I'd counter that by saying that my goal is 450 hp and I think that a coordinated package by LPE would probably work together better than my own piecemeal group of parts.

 

I just got an email from Tim Dyer at LPE. I asked him about the tc when they dynoed, and it was Unlocked.

 

If you put an aggressive cam with cnc ported and finished ls1 or ls6 heads, along with underdrive pulley, ported throttle body etc into an engine it will produce x-amount of horsepower no matter WHO installs it. The rest is dependent on the dyno readings and tuning. I admit that I think LPE's dyno reads lower than some other shops dynos. But, if your asking me to believe that LPE can't tune an LS1 engine as well or better than other tuners, well, that would be alot to be asking me to believe. IMHO dyno #'s don't mean squat! excellence in service, sterling reputation, and years, and years, of experience, mean everything, to me anyway!

BTW; The horsepower/torque in my sig was with the tc unlocked and NO dyno games, because they don't feel they NEED to impress ME. Am I saying some other tuners play games? I don't know, YOU decide. If you read between the lines, you might read it, and weep!

Another thing; The advertised 500 fwhp is IF you use ls6 heads. If your car, (as mine), doesn't have ls6 heads, you would naturally have to pay for the ls6 heads, (which I chose not to do). Therefore they proposed they could make for me, using ls1 heads, 475-480 horsepower. If you do the math, they exceeded 480 horsepower. And it's VERY streetable!

 

475 fwhp * .15 (drive train loss) = 403 rwhp - 300 rwhp (stock) = 103 rwhp gain / $6,500 = $63 per rwhp. That really isn't a bad deal when you figure you can spend $2,000 on long-tubes and gain 20 hp ($100 / hp).

BTW, if anyone can tune a car it's LPE..

Cheers,

I just dropped my 03 Z06 off at LPE in Decatur Indiana. The short stroy is I have a dyno sheet and sound clip of the GT1 Cam, which is what will be installed in my car along with the heads package. I was given the tour of LPE by Jeff Meyers, and it is unbeliveable what type and how many Hot Rods I saw. Some of the equipment 2 engine dynos and the control rooms. The chassis dyno. The engine assembly room only one person assembles engines at LPE, he has been doing it for 40 years and was Johns engine builder when he was alive. You could eat off the floor in that room. The machine shop, and everything else, all I can say is WOW. Next, was the array of vehicles work was being done on it was amazing. I regret I had to be taken to the airport for my flight home. Let me know and I will send you the dyno sheet and sound clip. I am sure you are aware, all vehicles are different. Jeff stated the package easily makes 500 bhp. the 15% deduct is about correct. The dyno sheet I received from Jeff shows 437 Rear Wheel H.P.437X1.15=502.2 By the way these numbers are attached to an 01 Z06. I expect a little higher numbers due to the fact the 03 Z's had better flowing heads to start. The cam specs are .636 /.636 I do not remember the duration stats. Anyway, sorry about the length of this. I was extremely impressed with how I was treated and the openness of the staff at LPE. Like I said I think LPE is the epitimy of Hot Rod Shops. THE WOW factor is off the charts. Yea, you can pay less, but I not sure you will get the same level of quality or experiance in the finished product. If I sound biased, I am. I did a lot of research and did not find anyone who was not satisfied with their experiance at LPE. I forgot to mention I am having a corsa X pipe, Hurricane cold air system and underdrive pulleys also installed. I will also get a hand held tuner just in case I need to restore the LPE settings.
