Well, it is nice to see you getting a lot closer to your goals! However, your mph still suggest you can get more from your 60-ft time. You have the mph or a car that should run like 11.0s Your HP is really near your mph so that is good too. If you can pull .2 to .3 off your 60-ft you will run 10.9 to 11.1 . . . how would you like that? That would be the best possible time I would expect.

Regardless your numbers are looking good. You are making me jealous!

Cool

Nice. Think you'll run the car any higher than 20 psi?

well i am kind disappoint about my trap speed, i was hope to see around 125 mph, but only got 122 mph. maybe i'll need to shift at 7500rpm instead of 8000 rpm. i'll give another this weekend, hopefully break the 11.54@122 mph with 20 psi!
thanks

I agree, I was putting down 500+ hp on my TD08 at 23psi and the TD08 is just a hair smaller than the T78.

450hp is a gd number @20psi, remember he only has to increase the boost to get more out of it.

It's funny that LUPE is going around bumping any 5 year old thread he can find relating to drag racing in an effort to convince the mods that there is a big need for a drag race section

Actually, all I did was take threads from the oldest page and bump them. I could have bumped a few hundred drag racing related threads but I wasn't drunk enough.

I've had to explain myself atleast 347 times in the past 4 days. Read my thread in the 3rd gen forum. I've got about 95% of the people backing me up.
