car weighs less than 2500 (track weight) with stock doors, fully caged, power windows, and factory hatch. still a lot more weight to come out!! add about 120 pounds with my street rims and tires on plus an extra sparco seat and full exhaust.
its perfectly streetable right now minus the expensive gas, thats the only part that sucks
that tq curve is some weird stuff that the headers is causing it to do. if you see my before graph, its not there at all...
throw some diesel in it, take out the spark plugs....
seems like all your mods are aimed at getting faster engine response time (rev time), not necessarily increasing HP. If you want increased HP, a really good valve job will make worlds of difference. Make it where blow down test will hold 120 psi with 0 leak by, throw in some headers, and you will see some bigger gains. I liked your increased compression ratio; what kind of injectors you got and what kind of pressure you got on them?

my car doesnt have a lot of stuff in it, pretty much this, i took out every possible piece off the car, and put back what was necessary.
ported heads, 5 angle valve job, 1mm OS valves, are done.
the car cannot breathe very well, that is one issue. i just got it together and have been working on getting some more power from it. i have modest cams in it cause i didnt want to bang the valves into the pistons just yet.
hard to recreate the revs and distance at 8500 rpms. i will soon though.
more air, better headers and the right cam could net this motor another 20-40 hp with no problem. i just am getting it there the right way and not messing it up.
stock injectors with 55 psi into them, no issues yet running 12 to 1 AFR. will be adding some 380s here soon.

Thats very good to hear that a NA has finally hit 300whp mark. What are the work involved in craeting this monster as i am going all NA myself? I'm just trying to push all of the power possible from NA.
Jeremy one thing I noticed is you said the A/F's are in the 12's. You can go into the 13's mainly because you are on race gas. It shouldn't ping or detonate even with the 14 to 1 compression. You can yield a lot more power man, you're doing a great job.
