Hey all, a friend of mine's uncle had a camaro that did a top speed run on the salt flats, (with all the safety equipment) and he took flight at 180... lost the rear... Can anyone confirm that? (lol) and/or talk about how you/to go faster than that...?

nolanr0413

i can only confirm 85 mph or more. the speedo only goes to 85 in my 85 trans am .

Beast5spdGTA

aerodynamics, fill the trunk with weight (free downforce)(probably better in the middle somewhere). I believe a 3rd gen firebird holds the stock body ave. at like 300.x mph. It was in Hot rod mag or car craft a yr or 2 ago. More HP = faster or better aero= faster.

what spoiler was he running?

GrueBlock

I'm not sure what spoiler he's running, but I can confirm 137mph without my hood on... I'm sure faster with it :d hah... but I top out in 4th gear (about 5500) I've been 5800 with the hood, but that has before I did the work to the engine and got larger tires... I'm guessing the stock spoiler... on an IROC

trans_am_ta_84

my friend says he had his up to 135mph... 86 trans am 305 carburated... i have the 84 and i was in front of him one day and my speedo was burried at the 100mph at 3 grand.. 3 more to go so i could have been over 100mph he told me we were goin 110 and we had to slow cause we saw a cop and the cop looked pissed but anyways aroudn 110 at 3 grand for me and i redline at 6.. so it's got a sdecent speed

I have an '82 Camaro with an engine swap, I'm told the block and bottom end came out of a truck, (so I'm guessing it may be a 350) but I was also told it had a racing CAM (I think the cam is probably only 10-20 over...) And I have camel heads... I took all my crap out, smog pump, power stearing, AC (yanked all the ac, 45lbs or so) But I was wondering... To me, my car feels strong, but suspecting what I have, I'm guessing that it would be slow... Since I whop on IROCs and the 5.7lit. Z28s... Other than having a 4-bolt main (probably doesn't do much) I think I may have roller rockers, (I've revved to 6600 before and my tac's red is 5, car tops out with no hood in 4th at 5500, so I'm guessing it's a 5500 engine) but yeah... does redlining 3rd and slamming in 2nd on accident (cuz shifter plate was nearly broken, didn't know) tell me anything other than a 4-bolt main? The engine has 25k miles on it, tops... the body has about 75k on it...? Any insight?

c4boom

none of that tells you any thing i have run a 302 up to 7,000 and it was a 2 bolt (yes chevy 302) with stamped rockers

fb305svs

been clocked at 142 by a friend in the police force on a local higway at 3am, and have had it up to 162.... yep, i can confirm that the back does get a bit light!!!!

i think that the rear bumper cover catches a lot of air from underneeth and creats a pressure area under the back of the car.

theoriticlly i could hit 183 by using rpm ranges, but it took long enough to hit 162 lol...

i have the normal wing spoiler, not the trans am one btw...

German polizei got me at 260km which is somewhere around 155mph, wipers were standing off of the windshield, trans tunnel was very hot and brake just threw puffs of smoke when applied, I tried to tell him that there was no speed limit but he wasnt hearing it. I let him check out the car and he let me go! Dont think that would happen in the states. I believe Lingenfelter has a 3rd gen bird that he ran at the flats and it doesnt look like too many body mods. Check it out

Drakar

I read he article about the 300+mph bird at the flats, can't find it right now, but the one thing taht stood out was they said they used a stock 87-90 wrap around spoiler (GTA/TA/Formula) style.

GrueBlock

I'd like to see that, if anyone knows where it's at, or can find it :d

fb305svs

it was a tta car... dunno if it was a production tta, but it had the 3.8 turbo motor in it, and a lot of power to boot!

Beast5spdGTA

It's Chevy High Preformance Jan. 2000.

It does have the 85-90 wrap around spoiler.
5000 lbs weight

damn nice setup

FruityOne

Pontiac unofficially built a 92 TransAm for a speed test in a magazine. Officially it was built to gauge how much power and speed the 3rd gen body could handle. Its a Twin Turbo 5.7L sbc. T3's or T4 turbos, not sure. 605hp and 704lbs/ft torque. Supposedly over 200mph, looks completely stock cept for Ronal LS wheels. Here's a link for pics of it.

And you can find some info on it in the following link.
The blue ‘92 Firebird sports a twin-turbocharged small block, and was officially built to gauge how well the third-gen chassis held up under extreme power levels. Unofficially it was built to run in a particular magazine’s top speed competition. The ‘Bird cracked the magical 200 mph mark.

www.TransAmGTA.com and www.GTAsourcepage.com have some info on it as well.

thanks for the info/links

I've had my 88 GTA doing 138mph and it wasn't feeling light on me at all. This is with upgraded suspension (listed in my sig) and 100% stock exterior.

Beast5spdGTA

Same here @ 135 and pulling felt very solid. AGX struts, solid AL LCA, brackets, AL driveshaft, and comp. eng . drag shocks. Big time, HUGE brake fade, when someone pulled into my lane.

Don't go more than ~110-120 with any cars in sight or get your brakes upgraded. I did kill a 02 maxima though pulled him by many cars after 115.

GrueBlock

yeah, I like the high-speed races... although the Pontiacs have better aeros than the Camaros... I still hit (calculated out to 142) against a 4.6L Mustang GT... he was on my *** tho... then he just disappeared like he blew something... *shrug* Ohh well... then I met a girl that her brother was racing down the 22 FWY in a Black Mustang GT and he blew his engine... Funny... Coincidence? I'm not sure, I didn't care to find out... haha... I'd prolly be in for some kind of drama... Anywho...

r90camarors

I have to agree about aerodynamics... I got my RS up to 140mph(per winaldl since speedo only goes to 110mph) with a completely stock suspension set up. I thought she was going to fly off the ground. Needless to say, braking wasn't really an option, as it started pulling left pretty bad. So downshifting was needed. Let me just say T-56's are sweet! BTW-this was done back home out in the "sticks" and a set of walkee-talkies.

I had my 88 GTA at 145mph and was reading 4000rpm so still below redline. I think I could have kept going up, but I ran out of road (and nerve!) 5.7 TPI with 700-R4. Oil pressure, engine temp etc all good to go. Never saw any after effects, car acted like it was no big deal. Engine had about 65K on it at that point. BONE STOCK car except for a tower brace. AND this was in CO at about 5000ft altitude!

r90camarors

Yeah, mine was at 3,500rpm in 6th doing 140mph. Unfortuantly I ran out of nerve as well, which I think was a good thing-I don't think the rest of the car would have held up. She was still pulling (albeit slowly) and it didn't seem to phase the engine. That was with around 155k on her.

blackztpi

stock weight on the toll road get me to 150 mph with 305and 2.73 gears. only mod to 35 was cam.

Aviator857

I peged my speedo once. I have the 120, I touched the needle to the trip milage reset switch who knows what speed that is. I wouldn't recomend doing this, it was 5 years ago and the car had 120k on it (181k now). The car was very unstable at this speed, and it was very hard to stop it but the car was actually very stable at 120mph.

The firebird that set the land speed record had a stock 90 aero spoiler and was a 1992 car
