in the cargo hold of the right airplane.

 

A stock L98 will go as fast as they say in the stats and specs section. Do you mean top speed wise?
I dunno, you tell us... It's got sleepy gears, should get going pretty quick after a while.

 

i got mine up to 250 kmh...s o maybe 160 for you american drivers. it was beside my buddies firehawk

 

Yea, Top speed wise. I got my gta up to 126 the other day and didnt know how much futher past that i could take it.

 

mine did 143...thats about all she had in her...havent tried in a long time.

 

also havent tried...been 130 with lots to go. that with 2.77's. now i got 3.42's so i know i wont get much over 140. but thats not the point of my car lol

it will do mid 13's in the right weather. its only got exhaust mods and a converter on slicks with alot of suspension work. full weight. thats not bad at all for a L98 car

 

Had mine too about 140 yesterday racing a 02 Saleen. Might have had a little left. Oh and we went from 45 and i stayed on the Saleens *** the whole time. He left first then I kicked and and stayed there the rest of the time, about a car and a half.

 

IIRC when the Michigan State Police tested the last of the L98 TPI Camaro B4C (the copcar package for Fcars) in the 1992 model year tests, they went around 150 mph. The actual numbers are in Edwin Sanow's book Chevrolet Police Cars 1955-1996, as summarized from MSP tests.

Some of that info might already be posted either here on TGO or elsewhere on the web (if you search for them).

 

yea..its not in the engine.. like its the tranny and gears... like i burried the needle at 240, or 145mph, but i redlined at 250-260 something.. kph

 

Ive got a digital dash, so i didnt know where exactly i was supposed to redline.

 

stock L98, i wouldnt take it any higher than 5000rpms... 4200-4300 is where it peaks.

 

i thought they peaked at 4800.. no more pwer after that... whats where mine shifts anyway.. but not for long !!

 

I got my 89 L98 GTA up to 150. Hell, Ive had my 84 MSE to 145 with a little to go.

 

aftermarket can pull alittle over 5000, but my dyno run peaked at 4200 but i think my timing was messed up so i think 4500 is all it has. my trans tho shifts at 5K even

 

I had my 1989 L98 Trans am at bout 148mph
with some more pedal left.. Of course, my car
isnt stock.. Im sure I would got 150+ mph with
no stress on the motor..

Im sure any L98 has to potential to see 165mph
+.. but not stock.. Like anything else in this world, It takes time and $$,and modification to get things to perform the way we want them too.

 

150 in my 88GTA at about 4500 rpm. I chickened out, the car still had some speed left, but i was outta road.

 

has anyone had their stock L98 TPI stuff up over 4500rpms in top gear (overdrive)?? TPI doesnt make power up over 4500 and this one guy is tellin me it will still pull past that

 

I noticed after getting into OD, and pulling past 3000rpm.. I could definatley tell my TPI car was having trouble gaining anymore signifigant speed after that, It was gradual..

Its not everday I have my car going that fast,
But I know its limits and also know going 150mph+
is not a TPI car's strong point.. Not to say they are'nt capable of it, They just aint good at it :P

 

guy was telling me that his stock 5.7 TPI with 3.73 gears hit 150mph. that would put him up over 5000rpms in OD

 

I hit over 150 mph . With the stuff in my sig. She coulda went more for a joke . I wasn't even at redline yet . That 5 speed OD really lets ya take it up there. Thats with 3.73's . My car peaks at 4900 with a siamesed set of Edelbrock runners( 4"deep)

 

when i went that fast i was to scared to looka t tack haha, i hit 150 in my full stock.. with few bolt-ons

 

Jesus christ this sounds dangerous the fastes i have ever driven a car is 78 i have only driven my camaro 40 because it needs work
