hey guys i just came back from midnight strip , with 20psi on my T-78 11.54 @ 122 mph on racegas and 12.1 air/fuel ratio before 6500rpm then 11.8 air/fuel ratio after 6500rpm. i don't know my 60ft since it's a midnight drag, but i launch the car at 7000 rpm with MT ET street tires. what you guys think?
93 black rx7 t- 78 greddy turbo kit
new greddy FMIC with 3" piping
heltech E6K
RP 1600CC fuel system
DYNO 450RWHP@20psi

 

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!

 

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

 

450 whp @ 20psi ? That tune must have been super fat.

 

^ with a t-78? i thought that turbo made larger numbers than that

 

seems like some low numbers on a 78.. any porting, any ignition mods? something has to be wrong with that

 

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.

 

Aren't the Greddy T78's smaller than a Garret or similiar T76/78?

 

i thought they were 63-66mm turbos

 

Thats what I thought also.

 

DIDNT ROY GET 456 @ 17LBS with a large street port. i wonder who tunned the car?

BTW lupe thanks for reserecting this 5 year old thread

 

This is an old thread....

450 HP is alot of power. There shouldn't be any complaints.

 

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

 

LOL - I saw that last night too.

 

I thought it was to get his post count even higher.
~3500 posts in a year....good god.

 

Thats what FDS and binge drinking will do to a man.

 

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.

why do you need a dragracing specific section?

should they make a autox one, roadcorse one? drift one? etc etc etc

 

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.

 

...except the ones that matter

 

if your talking about the thread in the 3rd gen forum, i read 11 Diffrent people say they like the idea in the first 2 pages @ 40 posts a page

not quite 95%.. closer to 8%
