Need a Favor

[Pete]

Can somebody do a search in CF for me?
There was a couple of Corvette C4 guys at the track (November 23rd) they video taped me going down the track
He told me he will post it in CF.
If anybody finds it can you post it here or email it to me.
I would really appreciate it.
Thanks
Pete

I notice your rear doesn't squat coming off the line.
Can you tell us how you had the suspension set up?

[XfireZ51]

Pete,

Any chance you'd consider going to GLD tomorrow?
Looks like it may be a decent day. ;)

[jonszr1]

pete glad they came up awsome runs by the way . i have a couple of ideas that may just get you there as you sit now . the spring in the back of the car seems perfect .anyway you canget a 100lb liter spring for the front ? that and disconnect the front sway bar . plus fill the gas tank up all the way should allow you to raise your staring line rpms by 500-700 which might give you the 60ft you need . you have more than enough mph to get there . what tire pressures are you running . in the second run it looks like you have them around 12-14. do you have a line lock for your burnouts ? or are you doing the 2nd gear stand on the break trick/? what do you go through the lights at now ? and max rpms you take her ? thinking that you might just get away with373s and just a touch taller tire which would help 60fts also .shared your vids with a suspension buddy this was a few things he came up off the top of his head . so i toss them to you to consider . would just love to see a little 10.85 (buddies prediction ) for ya :cheers:

Brad,

I've been thinking of a little more gear than I have now, 3.73 or 3.90.
Right now I am going through the traps in 3rd at 7k. Would the 3.73s make the kind of diff that would require you to shift before the traps and cost some et because of the shift? I know Lgaff has 4.10s on his otherwise pretty identical car to mine and he's going through at 7k but in 4th gear. His ET gain (~.4) seems to come in 60' and the front 1/8th. Our trap speeds are virtually identical.

[jonszr1]

dominic , my white car has 392 s which i like better than 410s. for pete whos rpms go higher than ours 373s with a touch taller tire would accomplish 2 things taller side wall for better bite and still go through in the top of third . 410 for him with his power would make launching a bitch. for us folk with about 380-400 rwhp . 392s would be the best gear. whaat i have found out that works for me is remove the spare tire fill the tank 90% full , you can disconnect the front sway bar(upright links ). put 48-50 lbs of air in the front . the air is worth a tenth and the sway bar disconnect is worth another tenth .our cars have enough mile an hr 116-120 to go deep into the 11s if we can get them to bite .. you have 2 ways to go stay with 3.45s and go to 16in drag radials 26-7in tall the taller sidewall will help your launch a bunch. or go to 392s and go with either the hoosier 17 or go to 16 in drs. i like the 392s for a street car 2000 rpms is about 77 mph which is where i seem to like to cruize plus fuel mileage seems to actually stay around 25 410s it goes down to 23.5. the 373s we would still have to shift into 4th before the lights and you dont have enough time in 4th to make up for the shift . another thought is the most economical way would be to keep your stk gears and invest in some good drs and play with the suspension . gear changes are a thousand anyway . coilovers would be awsome as spring changes are cheep and easy .you should be able to find a good used set of drs on wheels for about 500. just a matter of what you want to spend or what you want from the car on the street . .if i can help in any way just let me know .you guys have fun at the strip tomarrow :cheers:

Can't make it Dom.
Anyway they'll probably remember my car.
Now they only give you 1 warning.
Which sucks what are all those new ZR1's going to do put roll bars in there new Z's

I have DRM coil-overs 400/250 springs stock shocks.
Lowered ride hieght.
All sway bars on car.
FX3 set in Sport.
Battery in the back.

Brad,thanks for posting on CF.
Right now i use the Hoosier Drag Radial 335-35-17 and go thru the traps at top of 3rd about 7500rpm +- my gage is off a bunch.My shift light is set at 7200 and it's on as i go thru the traps.
I think 3.91's would be best,seems with the 3.45's i can't do better then mid 1.70's 60ft no matter what i do, if i can get 1.60's 60ft i pretty sure 10's are doable.*Pete

[jonszr1]

pete i will be done redoing the 392 s in a week want to make sure the posi is tight for you . what pressure are you running in the hoosiers ?. we found out this week in some testing that the foot print is better with 18 lbs in the drivers side and 18.5 in the passenger side . i know i thought it was goofy too . until i knocked almost 2 tenths off my 60 fts . something to try . if you go tomarrow you might try disconnecting the front sway bar . it made a big diff on my white car that also has coilovers . the front end really came up a bunch quicker . jsut putting things out there for you to consider . would love to see you get into the 10s . your carsounds so nasty . love your burnouts too .

[Pete]

Brad with the Hoosiers i was running 24lbs works good with the 3.45 gears.

With the BFG Drag Radials i run 18lbs.

I'm sure with the bigger gears 3.73+ i'll have to run lower PSI in the Hoosiers.

Brad thanks for the offer of using your rear end but with my luck it will probably break then i will have to buy 2 rear ends one to replace yours and one for me.
A friend has a 4.10 complete pumkin that i will try and decide if i wanna go with 3.73, 3.91 or 4.10.

I like my highway so i would prefer 3.73.

Thanks
Pete

With stock gearing, 3rd at 7k is around 118mph or so. I believe with 4.10's that 4th is around 130ish mph at 7k.

I also kinda wonder how 3.73's or so would change the 1/4 mile game. But I like how with stock gears you end up perfectly at the top of 3rd.

[jonszr1]

with 410 and 315x35x17 mt et sreet drag radials i go through the lights at 6700 6800 rpms. the trouble with 410s is its very tough to get a good launch to little and you bog to much you blow the tires off . i am wanting to try the 3.45s with the drag radials as i never have tried them . as allways i worry about breaking something in the rear end . thats why i to date have launched kinda easy. 200 miles 1 way to the strip allway is in the back of my mind . i just got an isusu trooper and a trailer so next year i can really try some things . pete does well with 3.45s. 3.73s i think would actually hurt as one wouldnt have enough time in 4 th gear. i am thinking that 3.92swith a 27 in tall drag radial in a 16 would be a good set up . reason you would have a taller side wall to help launch. m and h makes a neat dr that is the size i want in 16in /. i hope also to have a boltin solid 9in ford rear that would use our calipers done before march if time permits . i a friend of mine is helping me with that who is very good with drag setups . another key to a good launch is slipping the clutch a little at the start. in testing today at our little spot . i found out a couple of things letting out the clutch so that its all the way out in about 8 ft took 2.5 tenths off my 60 ft . dis connecting the front sway bar by removing the upright links was another tenth and removing the donut tire and carrier and filling ther gas tank 90%at least was another .08. we were using my g-tech which i use at the strip for the shift light and to download on to my computor . it has a program that shows tire spin at launch launch rpm actual shift rpms . i have it adjusted it to my car so its only .05 on et and between .25-.40 mile an hr . just today with the above changes got my 60 fts down from a 2.0 average to a 1.55 best and 1.60 high . the results may not be as good at the strip but mike thinks it would be close. so i am tossing the results out for you guys to consider and hope what we found out helps . opps i got a little wordy sorry

[XfireZ51]

One reason why I go to the track looking for trap speed and not so much ET.

[jonszr1]

i did too looking to see if my hanges made a diff .like exhaust . but had the chance to spend a whole day with an old friend who is a deid in the wool manual trans racer . he has a shop that only does drag rear suspensions . so i said i have a spot can you help me figure this mess out . i like others raced mostly auto trans cars for years . i got years worth of knowledge in 5 hrs . amazingly the car took the 40 launches without a hiccup. mike sure can row some gears . i felt like an compared to him . oh yeah i guess 55 is gettin old .:mrgreen: mike thanx tons :thumbsup: i can hardly wait till next weekend

[jonszr1]

geez guys. i just put my glasses on sorry for the spelling errors. did i say old . old with C.R.S.

[PhillipsLT5]

1 tenth @ 60 ft = 1.5 tenth ET

[flyin ryan]

1 tenth @ 60 ft = 1.5 tenth ETat least...can easily be up to 2 tenth's in the ¼ mile on a well sorted out combo.

[jonszr1]

you are right on the 60 ft deal g-tech showed 11.81.-90 on the white car after us changing everything before was 11.51-59
