Drag Racing Tech - what should my setup run? what can i should i change

383 lt1 with 12.5 to 1 compression
le2 heads
236/244 .568 110 lsa
ported intake
alternator relocation
3250 raceweight with me in it
full bolt ons
3.90 gears
3600 fuddle stall
315 mickey thompsons

rest of the setup is in the sig

its probably good for low 11's high 10's if it hooks but the 4l60e might hold it back a little. not sure what altitude you are running either so thats always a factor.

I would guess low 11s. Whats your suspension setup?

why a 315?

suspension is tubular k member, strange coilovers 300lb springs, tubular sfc, umi lcas, umi phb, i still need to get the umi tunnel mount torque arm and sum comp engineering rear shocks.

im goin to run the 315s because i dont think a 275 will hook on a 17

when you start racin it, change one thing at a time and see what effect it has on et

ya thats a good idea, i think it should react really well to a 200+ shot of nitrous once i get the suspension dialed in

all said and done, i think the 200 could put you bottom 10's high high 9's. really depends if it was optimized for the nitrous or not though.

well im hoping i set everything up pretty good for spray but im not really sure. the only thing im really worried about is the cam. it is 236/244 .568 on a 110 lsa. would this be to much overlap for nitrous?

They can. Tune your suspension for track conditions.

Assuming everything was installed properly and you have a good tune I can't see why the car wouldn't run late 10's. Might take some time learning the car and making some small adjustments but it is certainly capable of it. BTW, I would get yourself a set of 15" drag wheels out back so you can use that sidewall to your advantage. Definetly some ET left on the table by running 17" DR's.

For reference I ran 11.71 with my stock bottom end, LE2's, 224/230 cam at a 3500# raceweight. That was with lowering springs and the stock shocks along with a throttle issue that was only allowing my throttle linkage to open up about 85%. With my new drag shocks/springs and resolved throttle issue I am hoping for 11.40-50's. You are lighter and have quite a bit more power so you can definetly get that car into the 10's, good luck!

Looks like a good combo for both n/a and spray. I wouldn't worry about anything until you start spraying over 200 shot.:nod:

thanks guys i appreciate the good advice, i think i will invest in some drag wheels and a set of 26" slicks. i stil have some suspension pieces to buy so my hopes are high for this combo. i was really hoping for some 10.90s naturally aspirated! ik it is goin to take alot of work but hopefully with a little more weight reduction and some serious tuning ill get it there

also bolo what do you think my engine could handle as far as spray goes?

-the engine is a 2 bolt main with billit caps and arp main bolts
-forged rotating assembly from scat with arp 2000 rod bolts
-cp racing forged flat tops
-chromoly rings gapped at .025 (i think)
- i want to say corey at clayton racing said the rotating assembly was good for 750-1000

any input would be great as im new to nitrous

you'd have to see what the piston manufacturer recommends the ring gap for your desired nitrous shot.
