Hey guys, I was curious as to what you all thought about how much wheel horsepower I'm making with my current set up (mods in signature). Plus what you all thought I should be running in the quarter. This past weekend I went to a local dragstrip and my fastest time was 14.1@102, .4 reaction time, 2.2 60', Elev 1378'. I was running a T5 with a stock replacement clutch, on this run i dumped it at 3000 rpm's and it bogged off the line, my next run i tried launching at 4000 rpm's and fried that weak clutch lol. I'm currently in the process of swapping in a T56. I also forgot to mention in my sig that I'm running M/T 295 drag radials. My next run at the track will be memorial weekend and I'll post my updated info then. If you guys want post your horespower ratings with you 1/4 mile times. Thanks in advance guys.

You have another 1/2 second in that combo as it sits. Dump the weak Hot cam and throw something in there that will put those AFR's to good use and you should be in the low twelves (with traction). I would look for a roller that is 230@.050, .560" lift (with 1.6 rockers) on a 110LSA.

You need at least 10.0:1 CR for that cam and maybe even 1 3/4 headers to maximize what you already have. It can be good for mid to low 12's.

I was kinda hoping I could get into the low 13's but I didnt know if anyone else has done it with my set up. Now I have a little better understanding.

If you know the weight, you can get a decent estimate:

Thanks, five7 that's a pretty cool calculator.
I actually do know my weight, with me in the car it weighs 2240 ib's its gutted pretty well.

That has to be the lightest 3rd gen I've ever heard of. Must have a bunch of fiberglass & Plexiglas as well as being gutted.

So, you're making 172 HP at the rear wheels and 215 HP at the crank.

I don't think so

Husker Fan

Haha wow ya that would be the lightest third gen ever I must have miss typed.
The actual weight with me in the car is 3240 not 2240 haha my bad.

five7kid

Kind of figured that. Mine is 3440 with me in it, with just AC removed.

But, when you're from the boyhood home of Johnny Carson, we have to hold you to a higher standard...

Husker Fan

Haha that's awsome that you recognized Norfolk as that.
I don't blame you for holding me to that standard, we here in Norfolk have a lot to try and live up to due to him. lol

Seems to me like the cam is holding you back. Im pretty sure that cam is limiting your hp to the 400hp ballpark. I would go for a hotter cam.

Comp ratio is also a little low, I would have opted for a set of heads that bump the CR up to 10.5:1.

What pressures are you running in the MT's. 2.2 isnt bad but hopefully you can get it down a little lower.

If it gives a little insight, I ran 13.89 with a stock 350 tpi motor that I swapped a carb onto, with t5, 4.10 gears, babied it off the line with a 1.8 60 foot, 101 MPH, once the 60 foot increases for you, the car will be able to start getting more MPH, ET will drop by quite a bit. But as mentioned, you have a lot of parts holding back what can be a great combination, those heads are wanting more than that bump stick and headers are willing to give.

Husker Fan

Before I bought the AFR's and stealth ram the motor had 305 heads and a TPI, that's why I have that cam and that low of compression. I know its really limiting the potential this motor has, but I'm going to build a forged 383 with a custom cam in the future which is why I bought those heads and intake.

Right now I'm running 30 psi in the tires.

Well, I went to the track this weekend and I blew up my 10 bolt like I expected lol, so I won't be able to get an accurate times till later this year when I replace my rearend.

Bummer. What broke?

paul_huryk

Once you get the rear fixed, you should be making 350 to 375hp if all is tuned right. Not so sure a bigger cam is necessary - unless you want to make 425hp+. Should be able to run low 13's - high 12's with the power I mentioned.

The post i made....was the pass before the rear blew the next attempt, sorry you did not get a good one, but you are making power, mine was stock with a carb.

Husker Fan

Well I haven't had time to open up the rearend, it actually is still sitting in the street and hasn't moved in 2 weeks lol. But if i had to guess it feels like either the axle broke or the splines tore of the axle, I'll find out forsure in a couple weeks when I tear it apart. I'm gonna end up putting a stock 10 bolt time bomb right back into it, which I'll get for cheap. But as for a long term fix what would you guys suggest, should I rebuild the original 10 bolt with Moser axles and a Auburn posit unit? I've been told this will work for the power I'm making now. But I feel this is only a bandaid fix that wont last that long. Or should I save up for a Strange S60 which will take a long time for me to save up for? As you can see I'm kinda up in the air about it.

S60 is overkill for 90% of the cars on here.
do a 12bolt or even a 9" if you plan on more...

I have an 89 trans am full weight running 10.5 at 129 mph what would be my horsepower??
I have not had the car dyno'd but am curious as to the power.

This is something you need to make your own thread for. Jumping into somebody elses at random isn't very polite.

jarredsoon

Yes you are right!! I apologise, it was not very polite. I will make my own thread. Thanks guys!!
