Check my signature for details of my vehicle.

What would you guys suggest be my next mod that would result in a lower ET. I want to put my 365+hp to better use for the 1320. Im looking for the best dollar to performance bargin and Im considering doing a 3.9:1 rear gear swap. I know I need tires and new wheels though... My 60 foot was lacking @ 2.080 on my nitrous run but I didnt hit the switch until after that.

Meziere's electric water pump-$299 from BMR. I would definately entertain a lighter wheel/slicks combo. 2.0+-60'....you should be in the 1.6's or 1.7's with that kindof power.
Maybe some suspension or headers.

The other issue that I did forget to address @ the track was to let out the 50psi in my tires so I was running full pressure. I was launching without the nitrous by the way.

You wouldnt think that gears would make a big enough difference? I drive on the street a lot btw.

Another issue, I seem to be lacking on the torque side of things. Any help there? Could Torque Managment be hurting me to the effect of 30+ft/lbs? Where is everybody else seeing their torque peak @? I only have my numbers at the 5350 crossover.

As the gears will give you that SOTP feeling, I don't think you would benenfit the most from doing gears. You have NO2. You can afford to direct the money elsewhere. If you think your 60' time could improve, just put in some gears and watch it get worse. You can work it from any direction. I did all the power mods initially and had to play catchup with the suspension etc.

Very nice Dan. Get a converter next and look out. Stock gears on gas with a DR tire might help keep it hooked and shoot it off the line. Just don't spray it until above 2500 rpm .

got torque?

"Now, one of the best parts is that SCT is now providing (for auto trannys) the best shifting I have seen since the manual valve bodies. It shift so freaking hard from 1-2, 2-3 and 3-4 - if put you back in the seat and barks the tires, Hard!"

the quote is from this thread-

http://forums.bradbarnett.net/index....opic=30504&hl=

granted, bryan is running an ATI blower. but nevertheless, his shifts are the way they should be in a performance tune w/ an auto tranny.

torque mgmt.= bah humbug

I'm clueless when it comes to mods, but I seem to remember a lot of talk about the firmer lowering springs giving you less traction off the line.
The reason I remember it so well is the logic seemed backwards to me.

You have several options. Headers, x-pipe, 4.10 gears, electric water pump, underdrive pulleys. The biggest improvement at the track will probably be the gears.

4.10s but only with drag radials. Otherwise you'll smoke the tires more than Ken Gushi (the drifter racer). I think the gear swap will get you .3 secs and about the same trap speed or a little higher.

I get only a quick chirp with my 4.10's and Paxton, stock rims/tires. This is with the auto. I think it's as good as it gets as far as consistency!

Since I now believe Im going to be getting the 4.10s I should go ahead and swap the LCAs and get the adjustable brackets too. Which of the 3 BMR units would be best for my street/strip car? Im guessing I should just go with the
"race" units but is it really worth the extra $$$? I really want to improve upon that poor 60 foot of mine and get back to the drags within a week or 2.

My plan is to put the engine power to better use without trading out my radials for slicks. I want a car that can be fast on the street, basically defining a street/strip vehicle.

Also, where is a good place to buy the gears? Price is an issue of course.

Are you brake torquing the engine at all? I know a Paxton hits around 3500 rpms, but I figured you could still break'em lose. What's you 60ft times? They must be awesome.

Yes, if I brake-torque I can light 'em up all day long. I'm talking about letting off the brake and hammering it. Chirp, then it's gone. It's a great combination because there isn't too much power right off idle, then in about 5ft the gears start pulling like mad, then the blower pulls even harder.

I would never put a stall on this thing unless I tubbed it with slicks!
