Headed to the Dyno.

Spent the last few days installing my box of goodies that were waiting for me when I came off hitch. I have never cursed and thrown more tools in my life. Added a set of Texas Speed long tubes and 3" off road xpipe. While under the car I also pulled the torque tube and replaced my shift cable. The front was being held on with mousing wire and I discovered the rear grommet was gone as well. Surprised It didn't come off at some point. Also added a fast intake and 90mm ls2 tb.

Texas speed did a nice job on the headers but the ps header o2 sensor is too high and caused some issues with install. Everything else went on good. Headed to LMR dyno Thursday to get tuned up. So, place your bets. What will it dyno and what gains should I be expecting o see at the track. I have a solid idea, I just like the Internet speculation.
Mods as follows
99 c5 150k mile beater
Ls1, Texas speed lts with off road x, no mufflers
Fast 92, 90mm ls2 TB
Vararam
4.10s
3600 circle D
MT DRs on factory rims
3050+_ with driver
Current best 12.05@113 +700 da before 100lb weight reduction

Really hoping to get good air and see some 11.50s and 360rwhp on the dyno.

Id say 340-350's because of the stall and gears. More importantly with it tuned how does it drive?

I think you are right in line on your hp estimate, just based on other similar setups.
4.10 gears in an auto, that ought to get under way quick! You will need good track prep.
11.50's @ 116+ should to be doable.

A good bit of weight came out with the removal of the factory exhaust system, i need to weigh it. Removed the front sway, all the plastic crap under the hood including brake ducts. air pump is gone. Radio and all speakers removed. All the extra crap in the hatch is out as well as the passenger seat. I have race seats but I don't want to put them until next year when I put a cage in and remove the bags.

Ok, finally back. First pull was only 319hp. Made some adjustment to 340hp, then the numbers got screwed up. The Maf had came out of the boot so it was back to square one. Made a few more pulls and by the time the afrs were good the car was extremely hot so it put a damper on the numbers. Final numbers on a hot engine, with a standard correction factor in 90degree heat
336.50HP
337.61 Trq.

Big thanks to the crew at LMR in Houston. They have some monsters in there. I have a pic of the graph on my phone and don't know how to post it. Would someone mind letting me email them the pic and hosting it? What % loss should I be expecting with the stall and gears?
