If OVRMYHD was yours to tinker with where would you go with it next?

 

100 shot

 

Tell us what you've got right now.

 

Tempting for sure.

There's more I'm sure but just can't remember it all.

 

You looking for incremental "bang for the buck" ideas, or are you looking for big power street car, or do you want to really tear up the 1/4 mile?

 

The question's more what would you do, rather than what should I do. I thought it was already a big power street car that really tears up the 1/4 mile

 

what CR ratio ?
Sell those long tubes and put a 78mm turbo on that thing.

 

Does it have a/c ?


Yes -> Leave it alone.


No -> Install a/c.

CCW classics, and then leave it alone.

 

Then it sounds like you've already got the car you want. Yes? No?

 

about 11.1 TURBO I've definitely considered it but don't know how much it will take, what other things I'd need to change or what the potential would be. Total cost would be a factor too. I already have to spend on the roll bar.

 

 

fast intake and 100-150 shot,small cage...stickier tire,weight reduction.Oh and hold on tight!

 

It's the car I want but I'll probably never be done trying to figure out how best to make it better. I assume that's ok.
The question (again) was what would YOU do next if it was yours. Just looking for ideas that I maybe haven't thought of and details on those I have, as well as make conversation.

 

being 11:1 scratch the turbo idea.
assuming a good forged setup in the lower end,
Progressive 2 stage with a 250 shot of juice.
Add a small 1gal jaz fuel cell under the hood for some c16 for the nitrous kit.

Hold on and have some fun. Should net ya some killer ETs at the track.

 

Fast 92/92 setup. Bigger tires. 100-150 shot.

 

Thats 3 for juice,2 for fast intake,and 2 for more tire ...just saying

 

Slap on some of those awesome yearone snowflakes!

 

How is your traction? Does your car dead hook on the tires it has?
Otherwise you can get more ET without modifying the engine.

Adding a set of light wheels & narrow front tires, can get you at least another .1 to .15 sec.

More conveter will get it down the track faster, optimizing your combo.

Once you are getting everything out of it possible, add more HP.
Then a small adjustable nitrous shot to pick up the power a bit.

 

More stall, lightweight front runners, and a Fast 102 and you'll see ET gains.

Otherwise, drive the wheels off the car. Do an autocross, make a few legs of the Power Tour, go hit curvy roads, drag race as much as you can to whittle down those ET's. Just getting off the couch and enjoying what you've got is a low buck way to have a blast. Your car is awesome now and a good demo of easy LS capability.

 

My builder has suggested a supercharger and the supporting mods are already there, like the big fuel pump and 58 lb injectors. He says no more than 7 or 8 lbs of boost though, to be safe.
And yes 86White, I'm hearing you all. Sounds pretty good. I've wanted a Fast 90 or 92 setup from day one, just not crazy about spending a grand for what might only be 15 rwhp.
A 100 shot has come to mind a few times but I just hate the thought of temporary power even though it would be awesome to feel it hit. The torquer v2 supposedly likes n20.
Lonnie- Yes, with a good burnout, the car dead hooks 1.55 best, 3 - 1.59's and 1- 1.60 sixty foot times last time out. There were some ugly 60's in the batch too though but they were the result of poor burnouts. Something the wife needed to work on. She seems to have figured it out, mostly.
Some Drag Lites are on the list already with some skinny tires for the front and I was guessing 2-3 tenths and maybe 1 mph or 1.5.
A diet and bigger converter are on the way too. Plans are to go to a 4,200 Edge stall.
Not sure how much weight she's going to drop or how much the roll bar is going to add. The remainder of the a/c is coming out, cruise control stuff, and taking the dual fan set-up down to 1 bigger one. We'll see what else Tracey can come up with to misplace

 

Have you upgraded the brakes yet? Going fast is great, but being able to stop is pretty important

 

i would leave a tight converter in it and spray it.

 

Brakes are stock set-up right now with new rotors and pads. Absolutely no brake fade or rotor wobble even after hot-lapping it. Dad takes the first turn off and even that doesn't upset the brakes. Every fbody I've ever had came with crap brakes, except this one. In all the miles that Dad put on it 160,000+ it's never warped a rotor.
I would like to upgrade anyway though before we get much faster.

 

What kind of gains from what shot would you expect?

 

100hp should give you about .7sec (atleast .5) & 7-8mph at your current ET, assuming it hooks.

The faster you go, the more power it takes to make a difference. He same 100 hp is 1 sec & 10 mph on a 14 sec car.

Launch wise, every .1 60ft is appox .15 quarter mile improvement. This is why I suggest the converter & traction as the best bang for the buck.

Do not add a larger tire unless absolutely necessary. Carrying more tire takes more power to turn.
Weight is where it is at.

Look at PTC converters, they have a decent stall torque ratio & lock up pretty well on top. I like the precision industries for good 60ft, but they are loose on the top end.

 

Sounds nice for sure.

 

Finally, the clam opens up! That's the information I was trying to get out of you earlier! Now it's apparent to us that you want a street legal drag car.

Take time to research converters. You tend to get what you paid for. But first you need to decide how fast you want to go and if you want all motor, nitrous assisted, or boosted. If you want to leave short block alone then nitrous assisted is probably the best choice. Your transmission and rear axle will be weak links so start thinking of how you're going to repair/replace both in the future. (Keep in mind that working parts are worth more than broken parts when you sell. )

Honestly, I just kind of throw stuff together and am not worried about optimizing performance. Sounds like you're going to the next level and really need to think through the details. I'll be watching your journey and hoping to learn some things.

 

Thanks QWK TRIP. I want it all.

 

Personally, I like a big rowdy camshaft. I have found it keeps me behaving well on the street. If I drive a docile car with power adder it seems the only way to have fun is to stab the throttle. Eventually there will be trouble with the law. When I have a rowdy cam I can have fun just listening to the crackle-rump at a stop. It keeps me from stabbing the throttle so much. And let's face it, that sound is pretty rare these days so it grabs attention.

 

100 shot and pull it off the rail..... make your wife scream extra loud

 

Pull it off the rail?

 

Pull the fuel off the fuel rail meaning a wet kit? Lol

 

Well now that makes sense. Nitrous isn't something I pretend to know anything about.

 

I'd get a nitrous outlet wet plate kit for whatever intake u have.... and buy a timing retard box or do like I'm going to do and buy a separate pcm to use while spraying.... I like the idea because I have a full n/a tune and a full nitrous tune with having to change computers which takes 3 minutes

 

You can add the timing retard into the tune to activte with the nitrous, no need to replace the computer.

 

I do not do my own tuning so that would be a problem when I wanted to switch back to my n/a tune and a computer is 100$ vs. A 250$ retard box

 

You already know you need at least a 6-point before you go back to the track. Take care of that first.

I see a lot of things I would NOT do in the responses so far.

 

6 point is a done deal. Just waiting on garage time. Single adjustable QA1's are going to be replaced with double adjustables too. Stall increase from 3,200 to 4,200 is also in the plans as well as some Weld drag lites for track days with skinny fronts. That should put her well into the 10's in good air.
I'm weighing whether or not a Fast setup would be worth the extra coin. Chances are the car won't be seeing nitrous or forced induction any time soon. But if the short block ever has to come apart I will probably go forged and then go supercharged or turbo. It seems to me that a supercharger would waste most of the gains to traction loss and that a turbo might be better to avoid blowing the tires off. Either should see great gains at the track but realistically it is a 95% street car. It's Dad's dd for that matter. I'd like to keep him out of the ditch. Any kind of FI would require a bigger wheel/tire combo as the stock rims and Michelin Pilot Sports are already at their limits. I think some 17's in the front and 18's on the rear (with new drag radials for warm weather driving) might keep him going straight (enough)lol.
