1-Rob, I'm guessing you ran with 110 leaded gas?
2-Why not turn it up and run straight C16? How much more power do you think you would pick up?

3-So that crank is a billet 3.622 stroke?
4-I'ts very cool to see what your setup is doing with a longblock similar to mine, Harlan's or Scott's... I am surprised it does not peak higher, do you think a 116-117 LSA would push the peak up a lot? Is it worth it?
I should know for sure in a few weeks. As soon as Garrett gets my turbo done.

I'd love to see someone crank out 800rwhp with a 348ci setup.
We plan to run mine at 11:1 AF at WOT with the FAST.
5-So if the turbo maxes out the peak will be lower?
6-What happened to that T88? you had at the end of last year?
7-Are your heads o-ringed?

That's what's so great about the FAST system once you have it dialed in, you turn the boost up, and A/F stays exactly the same.
Regarding cubic inches - The cylinders were honed .005.

3.905 = 348ci, that's what ScottWS6, me, Harlan have... Very interesting comparos I am a big proponent of the stock cube movement.
8-How fast might you go with the new turbo?

PSJ- I'm not too sure how fast it will go. Just that it will go, or blow.
Allen - Thanks. You've got fax.

Thanks Z00!
BTW, the 701rwhp graph, for some reason lost it's rpm signal at the beginning of the pull. That's why part of the graph is missing.
Which is why I posted the next closest HP graph. I also have a graph of the 758rwtq number from earlier in the day (when the engine was cooler). I'll put it up too as soon as I get my scanner repaired.
Vince - It wasn't actually that your Fax didn't work...but the line was busy all day. So maybe I did dial the wrong number. Anyway, do those graphs make you happy now??

Rob : Congrats again if you dont mind i would like to ask you a question : Did you monitor your oil temps after races or ..lets say driving the car under a fw wot continus runs?I am interested about turbo Ls1 s oil temp.I bealive turbo Ls1s will face oil cooling problems.Maybe not on a drag track but on a few minutes of high speed driving under those hot summer days even with a oil cooler kit.Your data is valuable to me.Also this question is everybody with a turbo ls1 engine.Thanks

Rob,
Nice graph!
Are you running mainstuds and headstuds? Stock diameter headstuds?
What do you think the stock crank will handle with good rods and pistons with about 9.5:1 comp and the 74 turbo? Would 600RWHP reliably on pump gas be possible?
Also was this through a completely stock kit or your huge front mount cooler?
thanks again and great job,
Chris

Rob, so you basically built a "budget" motor with a bolt-on turbo kit. What is the difference between the stock PCM and the FAST system? I own LS1-edit, but I am going to have someone help. What was you fuel system like? Boost reference, sumped fuel cell, -10AN fuel lines? How about the TB, MAF, and exhaust components? How about a tuning down for street, "pump gas" run? I would like to see the M6 in it
