new times, not too good

[302 LX Eric]

venemus93 - Hit the dyno if you can. I think everyone would be very interested in your RWHP numbers, both before and after 'tweaking' it.

Good luck,

You're shifting too early. When I dyno'd my car the factory tach was off by almost 1,000 RPMs at the 6k mark. You'll need to play with your shift points to find the best ones, but don't be afraid to take that thing into the red-zone if you're looking at the factory tach. Next time at the track, do a run when you shift at 6k. Then on the next run shift at 6200.... etc, etc.

The E303 cam Cobra crate engine was rated at 320hp, if memory serves me correctly, and this engine has other mods done to it.

The iron-headed GT-40 crate 302s were rated at 280hp.

The aluminum-headed GT-40 crate 302s were rated at 320hp.

Ford under-rated the Cobra from the factory with the 235hp or 245hp #.

Trey...gave you ever run Sedanman. i remember him tellingme about a 93 Cobra he ran that runs high 12s at the track.

[venumus93]

Thanks all for the replys & please lets not make this a 'who-knows-what-&-who doesnt-know-what' thread now.....give it a rest, kids!

EZ: I'll let you know when I'm heading down that way. Fortunately or unfortunately, there aren't too many original looking 93 Cobras at the track, so it will be easy to find me when I get down there...but I'll let you know when I'm coming down!

Eric: I'll hit a dyno when I find one around here....just can't do it anytime soon due to $$$ & no time!

89 Cobra: Thanks for the shifting ideas! My buddy ran it for the last run at the track 2 weeks ago with me watching....he spun really bad out of the hole(2.67 60' time!), lit the tires in 2nd, then revved very high(he didnt look at the tach, just shifted by feel of the car pulling) then chirped 3rd! I have never chirped 3rd on dry pavment or at the track. Sounded nice. he still ran a 14.7 at 98.58mph.

trey: my numbers from the track dont show much improvement, but it does feel very strong on the road. I wonder a little bit about the mass air electronics that I got from my local mechanic, as it took away my hesitation problem, but I think he said it came off a '96 Stang??? I will try to find one off a '91 5.0 to make sure it's matched up with the A9L properly. I guess the dyno will show how the power is looking as well. only prob with the cam swap is tons of labor cost tring to get the a/c condensor out of the way, but I will definately do the springs at the same time to make sure all is well in there! will keep you all posted. thanks for all the good luck wishes!
Later!

Venumus93------I hope you can make it sometime. I love the 93 Cobras. You would have a good time here i think. Let me know when you would be able to do it.

Maybe i could also come up there and run also.

[lx mike]

I'm going to be meeting up with him in about a month or so. we'll let you know when and maybe you can make it there and we can get together.


I wasn't thinking about the factory tach being off. need to get an aftermarket one or try shifting higher on the stock one.

That would be fun. Let me know.

[Unit 5302]

Sedanman, get a clue. I was addressing 302 LX Eric's post trying to say that rated hp was accurate. Anybody who keeps up on the competition even remotely knows the LS1 dyno's at least 280rwhp which equals about 340hp at the crank. I like to use crank numbers because they are unaffected by drivetrain issues. If you put an aluminum driveshaft on a car, you're gonna pick up a rwhp or two. Less rotational mass, more efficient driveline, and that equals more hp at the wheels.

Yep, the Cobra computer stinks. The cam isn't any weaker than the stock HO cam when the 1.7's are added into the equation.

HO cam with 1.6's. .444"/.444" 266*/266* or 266*/276*
Cobra cam with 1.7's. .479"/.479" 270*/270*

Granted, the Cobra cam has less overlap, but the duration is very comparable, and the lift is comparable to a B303. The Cobra cam would be a good cam in it's setup for the HO engine, but with the much better flowing GT-40 Irons, and Cobra intake, it just doesn't have the higher rpm pull with an LSA so wide. It's not like the cam is a total POS.

http://chris.kellnet.com/chambers/shift_points.htm

All I had to do was type some parameters into google, and stuff like this started popping up. An LX vert running 12.7@107 with nearly the same setup as Venumus. 280rwhp from a common bolt on, stock headed 93 Cobra (equals 340hp) and Jeff Chamber's was making 325rwhp with the stock GT-40 iron heads, E cam, and GT-40 intake in trophy stock trim. The first run was about 280rwhp as well. Those are dyno charts. I'm not BSing anybody, and I don't care if your combo wouldn't run, Sedanman. If you knew how to tune your car, it would have unless something was wrong with it.

As far as the springs being weak, the GT-40 iron equipped Cobra heads also came with stronger, higher lift GT-40 valvespring setups. After 100k, it certainly could be weak. As for the recommendation of the B303, there are certainly reasons for it. With 1.7:1 rockers, it has a reputation for performing well. The 1.7's on the E cam make lift a little high. About .530.

I must admit, I hadn't seen the ratings on the iron crate motor in a long time. It's newer GT-40P counterpart dyno's about where I quoted, and the Cobra head isn't weaker by 60hp.

But who has the ability to measure the hp at the crank, its something you have to live with.

Still quite a bit smaller than the E cam.

Right and those trophy stock cars are stock right Tell me you are not THAT dumb!

Right this from a guy with a stock motor that admits to having not tuned it in 30K miles. My stang traped 105.5 with stock (not roller) 1.6 rockers. On a 156K short block with only 3.55 gears so not tuned my ***.

I would not reccomend 1.7 rockers to anyone let alone a car with a aftermarket cam, I would recommend switching to a E cam and trading or selling your 1.7's for a set of 1.6's. The simple fact that you will get a better valve train geometry makes the switch worth it by it self.

[Unit 5302]

So you trapped better than 105mph, and your combo was nowhere near 340hp. Sounds like it was at 300+ pretty easy to me. LS1 trap speeds on a car with no aerodynamics. Do you understand that it takes a lot of horsepower to put a fox above 105mph? Skyler traps 107 with TFS TW heads, E cam, and an Edelbrock intake. We'll see how much faster he is with ported headers and a holley. The setup he's running is good for 360hp or so, tuned, at this point. Since you can't convert, I'll put that into RWHP numbers for you. 300rwhp or so. I expect he'll pull a 110 all motor pass.

As far as the trophy stock cars, the 280rwhp run wasn't all crazy. The 325rwhp run was in trophy stock trim. The links are posted, dumbass. Take a look at them if you can figure out how to click on the bright green text. There are dyno runs connected. Course, numbers and **** mean nothing. All they are is fuel for idiots like you who see 30 mismatched combos run down the track, and decide you know about engines because of it. Go get an LS1, get rid of the stang and blow a load into the tailpipes before you go to bed every night. You'll be much happier thinking you have a better car.

The "get a clue" was aimed at your readiness to jump me any chance your dim wittedness has. You're about the sorriest SOB on this board. Yep, my 87 was out of tune, which therefore means, it was out of tune. Still trapped 100mph, even by relatively conservative estimates.

To me, just sounds like you need a serious *** kickin. Somebody to beat the ******* hell out of you. Put you in a hospital for a few weeks like my little niece has had to endure, only you're the one who deserves the stay. She's never done anything to anybody, but it's assholes like you who keep running their mouth. That way you'll have time to contemplate how friggen stupid you are.

No I did not have 300+hp my combo now only has 290 and it gives me 107.5 and that was with a missed third gear.

I don't understand that it takes a lot of hp to put a fox over 105 since my fox only traps 107.5 now (or then since I have done more mods)

I expect I will pull a 110 mph pass all motor very very soon.

Thats not what I said, trophy stock is allowed (if its the same as factory stock) to change compression ratio's and other changes, like balance rotating assembleys (and porting).

First I see a lot of matched combo's too.

The reason I think I know about motors is because:

A. I have had three different heads/cam combos on my stang
B. I went to school to be a mechanic
C. I go to purdue for mechanical enginnering
D. I am a engineer at Honda Engine Plant when school is not in session.

Thats why I think I know a little about motors

Nope, I love my stang way to much to do that. And I can't wait to bust ezridn's ***.

Yeah, because I tell it how it is I am stupid.

Right troll rule 101 if you can't out smart them threaten them with personal violence.

[Unit 5302]

Well, at least your schooling for engineering is why you're so arrogant.

290rwhp? I'm talking crank hp here pal. Not rwhp. 290crank hp is only about 240rwhp. That's not a whole lot more than a stock 93 Cobra dyno's at. 25rwhp less than Saleen GTS's 93 Cobra dynoed at with just a full bassani exhaust.

Anyway, I apologize for the physical threats. My little niece is in the hosptial, again. This time only for a few days, hopefully. I'm quite exhausted, and overly aggressive towards anything and everybody.

Apology accepted, I hope your niece is doing alright. Regardless of are veiw or thoughts I wish no harm/bad luck on anyone. I just love to talk car and race.

[ricekilla]

hey, fock drag racing, why dont we have a mustang works' boxing grudge match? that would solve who knows more about motors! in the spirit of the sport, i know more about motors than both of you put together! LETS GET READY TO RUUUUMMMMMBLE!

[ricekilla]

no biting or hair-pulling though ok?

[Motorhead302]

I don't know how much this will help the subject, but:

My friend has a '93 Cobra with 3.73's, MAC headers and off-road h, March pulleys, 70mm MAF (don't remember brand), a Tremec and a King Cobra clutch. with these mods, running on reg street 17's, I ran a 8.95 @ 80.xx with a 2.0 60 ft in the eighth.
Oh, it also has a full Kenny Brown level 5 suspension.

IMHO, the car in question isn't really running all that bad, it just sounds like it needs some better tuning. A guy I know who's an engine builder (he built Claire Stewart's 9.2 real street car) says that the cobra cam isn't all that great either. In the case of Factory Stock combos, he runs the HO cam, and makes much more hp and torque. The story as i understand it is that the engineers at Ford thought the customers would dislike the lack of low end grunt with the larger FRPP (then SVO) cams, so they closed up the lobe sep. to account, and traded high end hp for low end torque.

I think with a little practice driving it should run really strong. But don't underestimate traction, it is paramount to running good times. The next couple steps you make should definitely be better tires, and maybe some suspension mods.

...thanks for the reply, Eric. Now, how the heck did you run a 2.0 60' on stock rims & street tires?!!? If my 60' was a 2.0, my 14.13 run should have been a 13.8X run! Next thing for me is some tires, for sure.
Later!

[Motorhead302]

Well, the car had 275/40/17's on the back, and i think they were Toyo proxes, which are good tires, but i don't remember positively. But, as for the 60 foot times, it just comes with practice. In my 92 LX with 4.10's, exhaust, and pulleys, my best 60 ft is a 2.014, and the average is about 2.03 or .04, and that's on 245/50/16 Mastercrafts. In my '95 GT with 3.55's pulleys and exhaust, my best is 2.08, and average about 2.10 on BFG 245/45/17s.

Just get some practice, and go to the track some night when there aren't many people there, and run as many times as possible, and change one thing each time until you improve. Try a little more or less rpm, slip the clutch a little more or less, those kind of things.
