I bought an 89 RS (305 tbi 5-spd) two weeks ago and was wondering what you guys think about my time the car has a rebuilt motor and 3" cat back flowmaster with custom 49 state hypertech chip. It gteched at 16.9 sec. "I'm not comfortable with the shifts" but here's the odd part 91.6mph. isn't that a litle fast and what dio you think my best time could be.

 

That seems like a fast speed/slow E.T. Are you spinning the tires alot?

I thought that the gtechs always give you more mph, but the et in seconds is very accurate

sounds like you need more practice with the stick. You said it yourself. Your shifts should be near instantaneous

 

16.9 is what a 3.1 5 spd firebird should run. Stock ur car ran mid to high 15s and with a rebuilt motor with a good exahaust ur car should turn low 15s. Depending on ur clutch condition.......also if u are looking for a good mod for the car try a set of 3.73s. I have them in my 89 firebird 305 TBI 5 spd and it is way faster.

Stock mid-high 15's? LoL, I don't think so. Go tell that to Overclck and the guy that is running a 8.7 in his 0-60mph.

OVERCLCK is a 3.1 v6 and the guy running 8.7 0 to 60 has no cat back at all. TBI basher!!!!!!

BTW auto cars ran high 15s maybe a low 16 and if they didnt than it needs to be ran into a pole......

 

0-60 in 8.9, got a problem w/ that for my lil V6? I can't wait till my swap though. You guys make me feel good, I feel recognized.....

The guy running 8.7 0-60 would be me. And the quarter in 16.7 @84mph (g-teched). Before i put the gears in, performer tbi intake manifold, msd, and ultimate TBI mods, i was running the same 16.7 @ 86mph at the track. The car feels faster, but something is definitely wrong, which i'll be looking into this weekend. Maybe my clutch is starting to go? Stock 5spd TBI's should be running high 15's to low 16's with low miles and GOOD CLUTCH!!!

I found the two problems One my shifting I reran the car on a slight up hill last night and found that it ran a 15.8 still not asw fast as i wont it to be Two I dropedf the clutch and the car reved out but accelerated very slowly for the rpm's the guy that I bought it from said it had a center force with 30,000 on it, but it grabs like an old stock clutch.
I think it didn't get the fly wheel resurfaced.


Tanks for responding to my post...


I may be able to hit a low 15 with a new clutch.

 

i can tell u from first hand experience that a new clutch will make the world of difference. I just got a lifetime waranted OEM replacement clutch and had the flywheel resurfaced and i got a huge increase in performance. Even more so than gears!!! Thats the first thing i would do if/when i ever buy another manual equipped car. Serious do a clutch job and go try the g tech again......post results....

 

Mike, u had huge increase in performance because the other one was bad. Thats not an increase, thats bring it back up to par.

naw it wasnt that bad, i just felt it could use replaceing after 59000 miles. IT helped tremendously (hope thats spelled right) and as i said before reguardless of what n e one said that would be the first thing to get replaced if i ever buy another manual equipped car.

 

If the stock one was slipping then it was bad

theres no inbetween. Its either good or bad. You shouldnt really feel any increase in performance just changing the clutch if the old one was good unless you get a lighter pressureplate and that wouldnt be very noticeable anyways

 

pablo u are talking about a performance increase due to less rotateing mass, im not talking about that. I would feel an increase in performance becouse the clutch i replaced the OEM with has like a kevlar meterial or something to help grip better than stock. The clutch the factory puts in there really sucks *** . Thats why it amazes me that you could put a used one in ur car after a auto/manual swap.......ur times will suffer if u have a motor thats making any power above stock with OEM clutch

 

You dont know what you are talking about

you basically have only one way a clutch is gonna make your car slower other than rotating mass. That is slippage. If the clutch slips either you have a real brutal motor and excellent traction or the clutch is bad. If youve ever driven a car with a slipping clutch youll know what it acts like. Youll see the rpms flash up on the shifts after youve taken your foot off the clutch.. or it will just slip all the damn time beyond any sort of moderate throttle. Im using a used clutch and i have no slippage whatsoever. Id gain zero going to a new clutch. You are just trying to justify your possibly pointless expenditure.

 

lol right, once again the TBI god has spoken huh, go dumb another 5 grand into a motor and maybe u might hit 15s damn if only i would have gone with junkyard parts pablo........

 

What the **** is your problem? You are probably the least knowledgable member of Thirdgen.Org. You are like a bottom feeding parasite, you contribute NOTHING... yet you give **** to those who have accomplished something. Are you going to force me to use your favorite line again?

ok, ok....I've gotta put my two cents in (clink-clink) , There is a difference between a stock clutch and a performance one and that difference is the quickness in engaging the drive shaft.
If you race two cars (one=stock clutch, other=performance clutch) with all else being identical, the car with the performance clutch will always win. This mod can maybe get you an extra .1 in the 1/4

I think this is what the 89er meant.
