Purpose Built Road Course LS7 Camaro [COTW 1/19/15]
1 Attachment(s)
I've been running a lot of road courses in my L99, and really enjoyed installing my TVS2300 in my garage around Christmas 2012. The increase in HP was amazing - like driving a whole new car. I subsequently did a lot to help with heat (hex vents, splitter, big oil cooler) but still found my oil near or above 300 degrees after 20-25 minutes when I was running hard on VIR in the summer. Last time I was there in early July, I could only hit 135 on the back stretch, when I usually can hit 145. Was starting to think maybe I should stick to spring and fall track events.
Went to Summit Point two weeks ago and 5 laps out knew something was wrong. (see thread : http://www.camaro5.com/forums/showthread.php?t=374324). I limped home. Then, I blew my engine trying to diagnose the problem. The funny thing was, I had been talking to JusticePete over the summer about possibly getting a new engine. He's with Arrington Performance now. Arrington makes race engines. I went down to tour their manufacturing facility a few months back (about 45 minutes from VIR, in Martinsville VA) and was incredibly impressed. You would not believe the equipment they have, and what they can create. I griped about how heavy my car was in the nose with the supercharger in there, how I was always fighting heat, etc. Pete suggested they build me something based on an LS7 block (dry sump 427). I drooled. So, when the L99 went (will know more next week about exactly what was busted inside), it was like a message from Fate: GET YOUR CAR TO ARRINGTON. I called a guy with a flatbed, coaxed the car on, and we headed for Martinsville. It's in the shop now while Pete and his guys put together a plan that gets me a 550-600 RWHP LS7. Will post more details as we go. At the same time I have been thinking hard about stripping weight out of the car. Last time at Summit Point I ran without rear seats, seat belt anchors, and took out a bunch of plastic from the trunk and the rear seat area. Kinda loud but I like it. I might go further and strip the interior, and just leave my Kirkeys and cage in full time. Not really sure on that yet. Will see. Anyhow, will post details on the build as it goes. I cannot wait to see what Arrington comes up with :biggrin::biggrin::biggrin: |
Thank you for placing your trust in Arrington and me. I'll post pictures as we move through the build process.

That's the good and the bad of boost. The crappy thing for us roadies is it takes a lot more money to make big power NA so you have to be prepared for the sticker shock. I think an LS7 build will be pretty awesome. Keep us posted on the progress.

I already regularly get the Vette Grand Sport guys coming over between runs and asking what I have under the hood after I have blown past them. With an LS7, this will be like the ultimate track sleeper... :biggrin: Pete |

Good luck on the build and make those guys take lots of pictures and provide updates. I think it is also appropriate that Justice Pete make the handling a little better to go along with the new found NA power! :gossip: Travis |

I am sure not the fastest guy out there in the corners, and I have a lot to learn yet, no question about it. I've been working on adjusting my lines away from the generic line and towards a high horsepower line - so, on a big 180 degree corner, braking hard and going deep on the entry, cranking the wheel really hard and then getting right back on the gas to make a straightish line out. That's really different than the lighter cars that try to make a nice arc out of the whole thing. It's hell on the brakes but I have picked up at least a second on a corner when doing it that way. Anyhow, am eagerly waiting to see what JusticePete's engineering group will recommend. I know we'll get lots of pics as things come together. |
Maaaaan, just as I was mentally preparing to pull the trigger on the SLP unit, I stumble across this thread :facepalm:

SSOON, check out that museum thread of mine. how terrible and ironic that both our engines lasted and blew about the same time. my #7 intake spring broke. the valve dropped and it was over from there. i ordered a GMPP crate engine to swap in for the sept 26th four day event at the new track. my block is kinda ok. a lil scoring in #7. my guess is that we can clean it up, reuse the block and bottom end with new pistons and heads. this way ill have a spare if we need it for quick swap.
i got a stupid deal on this through my father in law. its an ls3 with asa cam and better stuff in the heads. its a sealed turn key GMPP product with 2 year warranty. http://paceperformance.com/i-7739382...te-engine.html |
