About to tune my car on 150shot and should make 600ish. car weighed in@3470w/driver. just looking to get an estimate of what it will trap. i was thinking 130-132ish sound about right?

 

Not a chance!
I would say 140+. I base that off of nothing but my own trap. Mine is an auto with a tight/efficient converter, but you should still trap higher than I did. I trapped 137. Your manual should trap higher if you are putting down 600 rwhp. You have may not have quite the power I do, but you may have a little more. Two things are for certain. (1) your car weighs less with driver. (2) your manual should outrun my auto in terms of trap speed.

Like I said, 140+ is my assumption. Let us know if I am wrong!

 

Just going off your sig, how does 357+150=600rwhp?


If your sig is still current, with you spraying I'd say 128-130.

 

I couldn't disagree more with your post. No disrespect of course.
He'll trap around 132-133mph most likely at almost 3,500lbs.

I'm curious to see a response to Chris' question too about 350 + 150 = 600?

 

No offense taken. It does make me scratch my head at my 137 though. I always thought it was a little low because of the auto with the stall. Oh well, the single digit is what I wanted!

Back to the topic: I am a little confused about the math too. I would guess something is missing from the OP.

 

sorry guys, yea the sig mod list isnt updated. the car currently has PRC stg 2.5 ls6 heads/tsunami cam package from TSP and put down 444whp. ill be retuning on e85 looking for 450+ and hitting it with a 150-175 shot. ive got the Nitrous Outlet 98-02 specific plate kit on it

 

Just be careful with the 175 shot. I know a lot of people have pulled it off, but I know of people who have blown heads or entire engines looking for the extra few tenths or mph. I wish you the best of luck as I've had my share, but don't blow the motor! Be careful. I see most of your time being picked up in your 60'. Go progressive or in stages. A 150 shot out of the hole and your engine AND rear could go. If they hold, your 60' will probably be worse!

 

You're going to spray 150-175 out of the hole with a T-56? Forget about my post above, if
you've never made a pass on the sauce yet you're probably not even going to make a clean pass.
I hope you have a built drive train and a stout clutch.

 

car only sees the track every now and then and i dont plan to spray 150 out the whole. i DD the car and run it on 555r's so im sure i would blow the tires off in 1st. i do have a progressive controller that ill mess with once i hook it up, but doubt ill even bother with 1st gear unless i get some mickey's on the car.

 

A buddy of mine in a 98 cobra that put down 603rwhp trapped 131 with a 5 speed. Weighed 3400 with him in it.

If I were you I'd make a 60ft pass then shut down then an 1/8th, then a full one. If you have any suspension issues you're gonna find out on the first hit. lol. Be careful.

You're going to need some time to dial it in and figure everything out.
I wouldn't expect much the first time out. Stock 10 bolt? Stock clutch?

 

10-bolt yes. another reason why its only been to the track 3 times. monster lev 3 clutch. i wont be launching the car hard for another few months until i build an 8.8.

 

With that much power and a stock 10 bolt and transmission, I'd say you'll run a 30 minute 1/4 mile cause they'll have to load you up on the flatbed and clear the **** off the track from your drivetrain exploding.
