Where will this combo get me? (1/4mile and HP)

Blownup5.0 · 02-05-2003, 12:18 PM

90lx hatchback 3100lbs w/me in it
5 speed
3.73's
aluminum driveshaft
complete dragracing suspension
stock shortblock
stock cam
1.7 rockers
stock heads lightly ported on exhaust side
Crane valve springs
Cobra intake
65mm T/B
73mm MAF
MAC cold air kit
underdrive pullies
longtubes
off road hpipe
2 chamber Flowmasters
E.T Street's

What do you guy's think it will do? I'm hoping for 12.90 maybe a 12.80 N/A and a 11.90 or 11.80 on a 150 shot of NOS.

I'm not good at bench racing but I think a high 12 on motor is way out of your reach. I'm thinking a 13.4 on motor with some good shifting, and a 12.2 with the juice. This is just my opinion from my own experience though... what ever that is worth.

For a mostly 'bolt-on' 5.0, I like the choices you've made (i.e. porting on the exhaust side, long tubes, drag suspension)...

all that said, I don't know about a 12.80 ET. I'd say a mid-low 13.

Good luck,
E

Well the reason I think it may go 12.90 or.80 is that I went 13.50 at 105.7 with the same combo but I had a RPM intake w/70mm T/B and 2.73 gears. I think it will go faster now because I now have 3.73's and a Cobra intake(hopefully give me more bottomend). I ran the 13.50 @ 105.7 on street tires(not dragradials).

Wow! I'm impressed. Nearly 106mph with bolt-on's and through stock heads is nuts.

I still stand by what I said though, 13.5's and 12.80's is a big difference.

But, prove me wrong. Go for it!

I think you can go high 12's. Since your on et streets you can launch hard so I say its very possible. On the spray I think you can go high 11's as i know someone who went 11.80's with a stock motor with a few bolt ons and a 150 shot

You can go 12's with that combo but you will have to launch @ 5000 rpm's and pull at least a 1.7 60ft.

My combo is very similar and I fully expect to run 12's.

Later,
