Pulled some more weight out today as well as worked on mounting the vacuum pump and the ram air.
Clearanced radiator support for ram air: 11.3oz
Cut V bar support for ram air/weight: 13oz
Overflow tank: 1lb 6.4oz
Driver side under fender metal: 6lb 3.5oz
Cool to see people showing interest in the stock internal stuff again. I’ve thought about sticking a stock LS1 back in my Firehawk and making another run at the record.

Glad to see someone still around that remembers the fun!
She already runs really good with the stuff you had done. Should be deep in the low 11s once you get it back on the track.
Thanks man. Yea that’s the hope. If I get everything done and good air I think I could clip high 10s, but am going to the track next week and hoping for mid to low 11s with what’s currently done.

That intake and ram air should make a huge difference in conjunction. Good 5 mph in identical air I would bet once the tune is optimized. The crazy thing I was thinking about is how many modern sports cars DONT run the numbers you already run. Just goes to show you how unoptimized most cars are these days.
**Note: the new style Racecraft brackets seem very over built and 7lbs. I plan to either trim them up or to trade out for an old style set that seem much more streamlined. I didn’t realize there was a difference until I was looks at old install pics to compare. I think there’s also weight that could be removed from the seat without messing with integrity
So I dynoed the car and decently happy with it. Still some loose ends to tie up power wise, but it made 364rwhp through unlocked converter and heavy street wheels (54lbs each) which seems healthy. Dynojet SAE not a happy dyno lol
Also proved the vacuum pump concept on a stock internal car. It picked up a tad over 11rwhp over baseline with GZ Motorsports pump and set at roughly 10in on back to back runs just swapping the belt onto the pump no other changes.
we couldn’t get a clean tq number with the converter unlocked.
