LS1: Cam ONLY Recommendations!
OK, I have FINALLY found someone I trust to do a cam swap for me. I have seen all the discussion about the G5 cam and the offerings from Fastech and MTI, but I have yet to be convinced. Most of the information I have found using the 'search' function has yielded me information on those cams in an LS6.
I think I will be doing LTs at the same time, so is 400RWHP possible with my mods and a cam suitable for a daily driver?
Let me know guys! :D

Maybe with a reverse split cam(F1, etc.) + LS6 intake + underdrive pulley. Pulling the cats would not hurt either if you tune correctly.

Re: LS1: Cam ONLY Recommendations! (C5-VERT)
What kind of results can I hope for with the F1 and my LS1 heads? And what is this talk of a 950rpm idle and such? I want the power, but it needs to stay drivable.

Johnso, You might want to post over on the LS1tech.com forum a lot of F.Body guys run cams with stock heads. I think you will pickup alot of valueable info. over there. You might also want to e.mail Andy at A&A Corvettes he changes cams like the rest of us change socks(LOL).

Re: LS1: Cam ONLY Recommendations! (MC98)
I LOVE my Comp XE-R 224/224 on a 112 LSA! It works GREAT in my A4, and I have it idling at 825 RPM in gear. I drove the car to the track yesterday, clicked off some 11.70's N/A, and drove home. :) FYI, we can get you any cam here at L.G. Motorsports. You don't HAVE to get the G5. ;)

Re: LS1: Cam ONLY Recommendations! (johnso26)
Same issue I was having. My choices were between the MTI B1 cam, F1 cam and the G2 or G5 cam from LG. After a while I decided to get the F1, but after talking to the techs at the shop it might be a little too much for what I intend to use it for (daily driver) the F1 is supposed to be a killer cam, just depends on what you want it for. I have the same mods as you ('98 A4, Blackwing intake, B&B Triflo exhaust, Granatelli MAFS) I ended up going for the TR220 Cam with a 114 LSA, after the install it dynoed at 332rwhp. Everybody at the shop and on the forum was telling me that with some LT headers it would jump up to around 360-375rwhp, so that's next on my list. Now that I think about it though, if I could do it over again I would probably get a little bigger cam...maybe the G2 or G5, but this is ok for me for now. I would definitely get the headers the same time you do the cam though, you should see a really good jump in hp then. Just do your homework first!!! :cheers:

Re: LS1: Cam ONLY Recommendations! (Trevor D.)
Trevor,
Quick question, the cam you are using has .581 lift, a cam that I had my eye on (TR 224) has the same duration except .561 lift. What would be the major differnece with going with the cam at .581 lift be... would you have to spin the motor harder? Will it do better in the 1/4? Thnx.

Re: LS1: Cam ONLY Recommendations! (johnso26)
FWIW....You really should consider a ASP Underdrive pulley as well with the cam swap...save your self the extra $$ on labor and get it done at the same time since you have to pull off the front end and the rack for the cam swap..... You will also pick up about 8-10 h.p......Just my .02

Re: LS1: Cam ONLY Recommendations! (vstella)
Won't the under drive pulley kinda screw the a/c and potentially other accessories? I never plan on running a big stereo or anything, but I need my a/c! :D

Re: LS1: Cam ONLY Recommendations! (johnso26)
I have the F1 and my driveability is awesome. I have tuning with idle set at 950RPM. PM me if you want details as the F1 guys are not sponsors. I can give you all the info you need. My numbers are in the sig. I would fully expect for you to see at least 400RWHP with stock LS1 heads. I have Z06 heads and I got a best of 421RWHP and 394RWTQ. My dynos on my sig are from my stage II heads and little T1 cam. I have updated my numbers though in the sig. Give me a holler anytime.

I have spoken to a few reliable shop owners and all told me not to waste my money on a pulley as they aren't worth it. Just my .02 :D

Well could you feel or tell a difference in the "supposed" 5-10rwhp this mod is supposed to yield? Somehow I highly doubt a pulley alone is worth 5rwhp let alone 10. Who came up with this number anyway? Has anyone actually dynoed their car before/after with this mod being the only change? I am skeptical only because a pulley netted me "0" hp and 1 rwtq on my camm'ed LT1 Z28. Yeah I know this is a totally different engine, but I still have my doubts. ;) Someone prove me wrong! :p:

Look at the pulley the same way you would an aluminum flywheel or better yet...Gears...
Most people show a dyno loss with 3.90's or 4.10's but their car is quicker..
Just making more efficient use of the HP/TQ at hand... :smash:
