Yeah and your 60' was awesome on that run too so I'm really impressed with your high trap speed. If only I didn't hit the rev-limiter on my 13.30 @ 108 pass I may have been a tenth quicker and a MPH faster. Oh well, we'll never know now.

I'd advise against doing more than the S/C'er and HBP on the automatic though. Doesn't seem like too many transmissions stay happy with that much power.
On the flip side my 6MT has been supercharged for 20k miles now and runs like a beast I just need to free up the exhaust. I'm only seeing 5-6psi and I used to peak around 7.5psi in the old car. I think with a larger diameter exhaust I might run more boost. Not too sure though.

The freer flowing the exhaust, the less boost you will see but will gain power. The increase in boost with a more restrictive exhaust is due to boost stacking.

Wouldn't freeing up the exhaust free up the flow pre-combustion as well though? If the air gets out easier wouldn't that help it flow in faster? Kind of eliminating a bottleneck? Increased blower efficiency - increased boost?
I can't figure out why I only see 5psi sometimes 6psi on this car whereas I was seeing 7psi regularly in my old car. The only difference is i'm on stock exhaust. Same boost gauge and i've hooked up a manual boost gauge recently to test the accuracy of the autometer unit. The autometer gauge is on its way back to autometer.

The blower flows a fixed unit per revolution. If there is less of a bottle neck on the way out of the cylinder, there is less going in and thus less boost with a PD blower.
Why are you seeing a different amount, can't say for sure. But there may be differences due to converter flash and the engine themselves. Not to mention boost gauges (even though it is the same, it can change over time). I wouldn't worry about an absolute value though provided the car is running strong.

I have about 271whp and I ran 103'ish mph on a busted clutch... maybe 104-105mph could have been possible, but I was never able to achieve that.
Keep in mind that the S/C'd Comptech 6spd with S/C, Header, Exhaust, clutch/flywheel on BIG rims (like your 20's) hit 104-105mph!! That car made 305whp.

I know low 13's are achievable... I was running that.
However not sure how 9800 rpms works on this motor in any gear

That's the biggest BS I' eva heard. V6P used to have those posers.
First you ran 13.2 on dubs, yeah right
Now you fuel mapping goes to 9800rpm, sure
And what FMU do you use? Show you dyno, timeslip and engine pics (including J35A* stamp on the short block) and put fork and condom on it to prove it's yours. Until then, you made an ass out yourself.

When I installed my discronificator I was able to control wheel hop due to select focus of the moon's gravitational pull. That, combined with the super helical sublersinator, I revved to 15k on the stock valve springs. Those silly F1 guys need to learn this and stop using that hydraulic valve control.

Ah, I was waiting on the flux capacitor as my triaxialmotoflex seems to be holding strong.
Oh, and the F1 V8's next year should be turning 20k plus.

But here are the theorectical top speed for each gear with a 9800 redline:
Code:
Gear MPH 1 57.4 2 91.1 3 132.8 4 180.6 5 231.4 6 292.8
