Getting ready for a future grudge match VS. a Mustang

[johnnyttype]

i think the numerically lower gears like the 3.36's r better for buick engines because of their power band and the fact that u normally dont wind a stock gn past 5500rpm. ive heard that people have actually gained time by going from 3.73 to 3.42 in a buick or 3.42 to 3.23's! someone else could explain this better than me but i figured id give it a shot

[TURBOPOWERED68]

I get it
But what about making up the deference with a taller tire for example
3.73s with a 28 inch tire.

I had 3.73s with 26 inch tires on my Monte/GN powered and I loved the way it shot out, but I did run out at the top end. I never got a chance to run 28 inch tires.

Anyway it's looking like 3.36 are leading the pack.

You need a full tank of race gas, SOme good hooking tires and id go with 3.73 and 28" tires if over 3700lbs. If 3600-3700 go 3.55. If you are gong to get it under 3400 id use the 3.36 gears. Boost, timing, traction, tune. You better get some drive time on it.

[johnnyttype]

after doin some calculations, i would think atleast for now, 3.55's would be a better fit for the car. a 28" tall tire with 3.36 gears in drive would be 124mph @5000rpm which i dont see ur more stock engine doing right now. the 3.55's would get u to 117mph @5000rpm which may still be alittle more than u will need for awhile. of course the mph's will be alittle lower (by 2-4 or so) if u calculate some converter slip in there hth!

Correct me if I'm wrong....and I'm wrong quite often.

Shouldn't "smack-talk" be done when you are sure the car runs well? Has all four sneakers on the pavement?

I'd tell him the car makes too much power, and you are a kind person saving him from certain humiliation. Push the date back, and tune the car for an all out balls run.

[TURBOPOWERED68]

I though that with the shortage of power that I have that the 3.36s would chock me up.
I was actually looking at 3.55 or 3.73 but the votes keep coming for the 3.36s

Even thou the 3.36s would be good for me if I keep the car.

Chevelle's... How heavy in reality? Two of my friends have one, a 68 and a 70. The 68 owner said that if his weighs the 4,000+ they're remembered to weigh, his must have a serious rust issue he doesn't know about!! He's scaled it and told me it's under 3400 empty. And btw, it's got a 454 under hood, and a 10pt roll cage.

Anyway, get yours running well and test it before you go racing. That Mustang, driven properly is easily capable of 12's w/ 288rwhp and I don't think your Chevelle is there just yet.

PS 3.73's sound good to me, if not 3.55's.

You are way wrong
Smack talk begins the day your friend buys a sport or performance car.
I am in a win win situating he is over $10k into Performance parts and labor.

I have less then $500 into performance and labor, well the posi rear will put me at about $2500. But still a long way from $10K.
So he really needs to put one hell of a Beat down to talk smack.
We are friends so not really a big deal.

BTW today I told him about this thread and he was cracking up.

I haven't put it on the scales (sh*t I haven't put tires on it)
But according to the chevelle site the
68 with a 307 No ac is close to or at 3300lbs
My car has very little bondo and no ac, but the sound system will add some Lbs. to it.

[notacarlo]

I told you I was probably wrong.

[t-typex1]

I would wait until you drive it and work the bugs out. I too have a grudge match with a 91 stang with a built motor. I tuned some the first time and thaught I was running good. I won as a result of no traction on the mustangs behalf 12.55 to a 12.62. You dont want to try running him without some test runs on yours first. get the bugs out. BTW, I vote 3.36 gears as well. The turbo will make the power.

[TURBOPOWERED68]

Well it looks like i will never catch the stang
he just ordered a super charger that suports an extra 120HP.
i will be doing the install with him as soon as it comes in.
this sucks big time.

[Amelio]

Don't give up... maybe for now but you have not even put your car to the pavment yet ther is still time to lay the smack down

I was trying to finish my car to race my buddy's '01 ZO6 he had a ton of stuff doneN/A put 433 to the ground. He was actually coming after me a few years back because my car put down 430 but I did not tell him it was only at 19psi

Any way I just recently got my car back on the road and he just sold his car so now we will never know who would have won. My brother does have a few friends that have some heavy weight tuners gunnin for me so I still have my work cut out.

My suggestion to you especially with these turbo cars is get the thing running and then start practicing and tuning because with my exsperience they never run like they should right out of the box

oh and I had a '68 GTO with a 455ci non air it weighed in right around 3500 and change. Your chevelle is about the same as a TR so 3.36 geras would be the way to go.

If you were running a 4 speed and a big block I would say 3.73 and some tire but these little shoe box engines are a different ball game.

Good luck

Dont count yourself out yet. These little buick turbo motors have been known to surprise people with their capabilities. These motors have TONS of torque and a wide power band. As far as the Mustang,even with a supercharger, theres still putting that power to the ground. Think of the smack you could talk with a win, even with him having a SC!!

[TURBOPOWERED68]

last week the Stang put 396HP at the rear wheels on a Dyno.
and it has been on the road with NO issues.
So it looks like i'll have to tone down the smack talk and get ready for my beat down.

The numbers mean nothing if you can make a fat torque curve, use STOCK 3.42 gears and a good Art Carr 16930 Non lockup torque converter. That TC will work wonders. Get good sticky tires and 1 airbag and some good, new front and rear shocks to prevent rebound and loss of traction. If those numbers for the mustang were made on a dynojet, and was tuned on the dynojet, then the tune will be different for the street. My cobra made 483rwhp with 11psi and only a Novi 1000, on 91 pump, no alky....14 degrees timing max. It had a live rear in it instead of the independant rear, with 4.56's (ideal for a cobra). I was fishtailing at 90-100mph. It would hook after my shift into 4th and then the millenium falcon warp drive would kick in and it was gone. But by the time my car hooked, the other guy would have finished the race and be in a parking lot taking a nap. It takes suspension study, application and driving experience to make a 5 speed car go fast. With a TR, it doesnt take much skill at all.

Enuf smack-down talk--now that he has "more money" than you & has his turbo/supercharger/whatever. You now need more time & $$--or prepare for an a$$-whoopin (unless you scare him enuf to "smoke-em")--not likely if he afforded sticky tires...

1) If you're hung on Richmond--then 3.36 posi is the ticket,
2) 255's (G-15's) @ 27" OD will be fine (but the stickier==the better)
3) If you can't afford alky--do TTwk chip ($90'ish) for race gas,
4) you need an adjustable waste gate controller ($90'ish) for higher boost control,
5) You will just leave-the-line with "near the max boost" you can hold with footbrake,
6) PowerPlate will do nothing for power--just help protect your engine from air-fuel maldistribution,
7) you should never have given away any secrets about what's been said on this website

These turbo buicks are all about torque--not rpms/peak Hp. At 5000 rpms--you're done. Geesh, do you even have a Scanmaster & FP & ext'l boost gauges to "tune"...???
