it's a 1990 lx notch. it's got a twin turbo set up on it with t3/t4's running about 9 lbs on the street and 14 at the track. the issue is that it's still got the stock 302 block in it, which isn't going to handle 550rwhp for too long, so it will blow up eventually. i'm hoping that it will last at least for next race season before we need to get a new one. once it does blow, we are debating what engine to go in it. looks like we're either going to get a 306 dart, or possibly a 327. either way it will be built with low compression for boost, and we should be able to push the levels at least to 18-20 lbs at the track. that should last a lot longer than the stock 302, and hopefully nothing else will break in the process! we've already rebuilt the rear end three times this season alone [:@]

 

Gee, you dont sound too fond of the old 302. I love those motors, even stock they take amazing abuse. You should build one with forged pistons, a stroker forged crank, the good heads. I'm not a Ford expert, but you can do so much to those 302's it's silly. What about a 351 swap. I saw a late 80"s GT with one, it was nice.

 

i do like the 302, but for the power we are looking for it's just not enough. it's taken a lot of abuse in its current state, i'm just not sure how long it will last with the current set up.

 

So you wouldn't consider a swap if it blew to the 351 like Paul said??

And are you staying at 550rwhp or did you want a helluva lot more out of it and thats why its gonna blow?

Holy **** you've rebuilt the rear end three times?? Doesn't sound like the car can handle the amount of power your putting to the ground. Is there any other rear end you could fabricate that would hold it up better? Then again the motor seems to be the main problem to you, not the rear end since you said it was gonna blow anyways.

Yeah I hope for your sake nothing else breaks after your swap. Thats never fun [:@]. And is the 18-20lbs going to be peak? Or like in the SRT's peak to 14 drop to 12ish? And with the new motor obviously you'll have alot more power, isn't that going to cause more problems with the rear end holding??

I'm just wondering cause I'm not a Ford fan, but this is interesting to me

 

Be unique and put in a big frickin' 460 in it, bore and stroke it to within an inch of it's life and destroy just about everything next to you.

 

Could you fit a 460 in that bay??? If you could that would be literal insanity on wheels. And one big traction problem lol. But DAMN how that puppy would go!

 

there wouldn't be any room for tubos with a 460!!!

when the 302 blows we are getting another motor, just not a 351. we're probably going to get a 327, maybe a 331. we have to build it low compression to handle the boost levels. a 351 isn't a bad idea, just not where we want to go at the moment. for our purposes and the parts that we already have, a 327 is a better option. space is also an issue in this car, the pipes take up a lot of room!!!

the rear isn't really a problem, it's that we tried to fabriacte a custom rear using the housing from the 90 and axles from a 95, along with a set of cobra brakes. the first time we broke an axle, so that was fixed. then we stripped the gears, which wasn't a big deal because they needed to be changed anyway to a lower ratio. the last time it blew it was because the bellhousing was crap and wasn't seated properly causeing all sorts of failures. we think that it's all straight now, and it shouldn't be an issue.

the 550 rwhp is what it's putting out now on the stock 302. the turbo sytems is capable of 25 psi, and we would like to be able to use more of that power. so that's why we're going to build the engine up to handle it. 20lbs is a conservative estimate of what we could run on a built block, really we will probably be able to push a little more.

as for the boost levels, this car doesn't fall vicim to the spikes as much as the srt does. if it spikes to 20 lbs, it will usually hold right around there as well, maybe go to 19lbs. we installed a 2 step to allow for loading at the line to reduce lag at the launch. if we can ever get a good run, i'll let you know exactly the boost profile, as we hooked up a laptop so we have detailed readouts of what's going on. we won't be running it again until next season, right now it's in for some new paint and a new cage, as well as an interior swap and some new seats.

here's some pics of the car and parts...

this is when the gears went on the rear:

trying to fit the dr's from the mustang on my srt! lol

 

DAMN! Not a ford fan, but thats wicked fkn cool what you've got goin on there. Thats k I can wait till next season to find out how she does on the track. Those turbos are SICK looking. Damn. I wish the SRT would hold its PSI stock. Damn spiking. Its all good though. Hopefully it all works out for you with the swap and all once it blows on you, and you can manage to get even more HP and TQ and better times. GL with it

 

thanks

now i just have to convince the bf that we need to install a booster seat so i can still drive the damn thing!!! i've been having issues seeing over the hood since we changed it (went from a 2.5" to a 4" cowl, which is partly why it's getting new paint). i can drive it on the street some, but there's no way that i can take it down the track as it sits without a booster, i'm just too short []. if only i was about 3" taller, it wouldn't be an issue lol. the problem is that tech inspection won't let me drive with the booster unless it's a permanent fixture (welded to the floor and the seat bolts into it), but with that configuration, the bf can't drive because he hits his head on the roof. so we are looking into trying to find a nmra legal removable booster. anyone got any ideas? it's more imporant for him to be able to drive then me of course, since he runs nmra true street in it, and i would only really drive it once in a while. so for now i'm reduced to pit crew until a solution appears. but that's ok, i still have my srt to take down the track when i feel like it.

 

Lol awwwwwww how tall are you? I'm 5'10 My legs are too damned long. My SRT seat is all the way back. Though when I first started driving it, it was all the way up cause I had never driven a stick before.
