new times, not too good
 

Hey everyone!
Got to the track a week ago for test & tune night, got the C&L & A9L in there, 15 deg timing,seems to be running fine, no hesitations, etc. Iced it down & in 4 tries could only get a 14.133 at 99.53MPH, 2.188 60' time. A guy there told me too much spin off the line(still have street radials)& too much spin in 2nd gear, so I should try to launch at idle next time & 'short-shift' 1st gear to get rid of 2nd gear spinning. I hear tons of people say I can do much better with this setup & then some say that is all a 108K mile 5.0 can do(I know better from reading sigs in this forum). I have issues in launching still & I think that's where I lose a couple/few tenths in ET. I'll keep trying & let you know what happens! Later!

p.s. anyone want to donte some Nittos DR's to the cause?? mccrearys??(lx mike!)

Did you pick up any from your previous times?? As for the tire donation i might have to ride up there sometime and see whats the story with your driving! :p What night do there run test and tune??

Thats not bad, im usually in the 14.0 area with a 2.0 60' on street tires, on a shorter 25 inch e.t. street with a 5k launch and 1.8 60' i went 13.57 @ 99, so i assume you could do the same, i been around the 97 mph range lately (been hot here) but at the track its all about sticky tires, no radials can hold the stock power of a 5.0, i have sportsman pros and smoke through 1st with just a light launch. nittos might give you the extra hook though, dunno never used them.

I spun through 1st with the nitto's when my car was stock and now it spins through 1st part of 2nd and chirps 3rd.

I have to launch at an idle....2.0 60ft's is all I have been able to get with the nittos.

The only time I ran slicks at the track I got a 1.7 60ft witha 3000 rpm launch.

My point.........If you wanna go fast get slicks!

Later,

I went from a 14.18 to a 14.13 with my A9L & C&L. my 60' time went from a 2.157 to a 2.188, so it got worse(due to my driving).
I think my recent mods made it better, I just need to drive better. My tires suck, yes, and guys around her can get 1.7-1.8 60' times on nittos on their 5.0's, so I will lokk for some great improvement with those.
Mike, I go to Fri night test & tunes, will stop by this Fri on the way to FFW in Gainseville Fri-Sun(just to watch). If you can make the drive to Orlando Speedworld for a Fri test & tune, lets meet up & I'll let you take the Cobra for a spin(see how easy it isn't to hook up!)
Dark & CCoupe, thanks for the posts. Tires are definately my next mod, but I will stick with street tires(Dr's) as I want my car to run all the time in true street trim.
Later!

I'd expect a lot more trap speed out of the Cobra. You have the same mods most people would make to pull themselves down close to the 12's. I don't really know what's up? Is it not pulling up top?

UNIT: I'm not sure about my top end...I do have the stock tach so I really dont know if I'm shifting when I should, etc. I shift at 5500-5600 RPms still feel like its pulling at the time. My whole best run is as follows: .830 r/t, 2.188 60', 6.016 330', 9.170 1/8 @ 79.17MPH, 11.859 1000', 14.133 1/4 at 99.53MPH. Again, I'll try an easier(less spinning launch with no bog) to see if I can drop those times in the 1/4. As far as trap speed goes, dont know what's up there(I haven't been able to hit 100 yet). I did have a valve spring bust at about 50K miles, replaced under an extended warranty by Ford, but for some reason I feel that has something to do with my bad times. Guess I could get a dyno test to see? Any suggestions would be great.

Thanks! Later!

wish i knew too! our cars are alike in many ways only difference is that i have 3.73's and you have 3.55's and also the cobra has a 70 mm t.b?? also the gt-40 heads. the factory tach is known for being off especially during quick acceleration so who knows what rpm's your realy shifting at. What tires are you running??

I'm running Falken ZR 245/45 17's ont he stock rims. My local mechanic guy here today said my treadwear rating of 340 shows that these tires WONT hook up, & said I was good to get 1.57 best 60' time so far....BTW, email on it's way to ya!

Your trap seems almost right. Maybe its a tad slow, but who knows. With my '86 with th old set up(before intake, AFPR, 255, etc,...) i ran the same 1/8 times but you seem to pull harder on the top end than my '86. Keep praticing man. I would love to meet up with ya sometime. I am in palm beach though.

Just keep having fun with that car. Since it has the 17s, you might consider the BFG 275 tire. I like those.

Oh yeah, a fox that should be making 300hp+ should trap better than 100mph my friend.

The combo as it really is

Underdrive pullies
Cold air induction
C&L 76mm MAF
65mm T/B
Cobra Intake
24lb/hr injectors
GT-40 Iron Heads
Off road H-pipe
A9L Processor
3.55 gears

Remember, it's not a 5.0HO, She's got a Cobra mill in there. That combo should be making a solid 300hp. With that kind of power trap speed should be a lot closer to 104mph+. There are stock fox's with 5.0HO mills trapping near 100mph as your weak headed 86GT demonstrates.

VenumusFirst off, you need a dyno tune. I've seen results posted where people have picked up 30rwhp with a tune. Also, you need an aftermarket tach. Some tachs are off by as much as 800rpm. You could be shifting at 4800rpm and not even knowing it.

Unit - I thought 93 Cobra's were rated at 235 or was it 245 HP? Either way, how does a CAI, C&L meter, Pulleys and an H-pipe give 65 or 55 HP? That seems like a bit much to me.

Venumus - for what it's worth, the couple 93 Cobra's that I've seen run at my local track were running close to what you were running (ET wise). I know that one of the Cobra's had gears (3.73's I think) and complete exhaust was running high 13's with traps a tad north of 100 mph. So, with street tires and pulling 2.18 60's that not too bad. Drag radials will definitely help you get into the 13's.

Good luck,
E

Unit there is no way that car makes 300hp, I bet that your friends have a E303 cam in there combo, which makes a huge difference.

Venoumous put a E303 in that car and you will pick up around 3mph in you traps I had a very very similar setup 3.55's the whole bit except I had a electric fan, E303 (stock rocker arms), headers, and in a light LX coupe. On BFG 255/50/16 dr's I went 13.2@105.5.

Good luck

I agree, but with just a E cam that car is gonna be fast. As for now your times are probably about right, except try to hook, I reccommend BFG DR's I have had both BFG's and Nitto's and my third set was BFG's if that tells you anything.

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 E cam and the combo listed should produce a 330-340hp combo that'll run down LS-1's.

302 LX Eric, I stand corrected. The Cobra intake, GT-40 heads, 24lb injectors, 70mm MAF, 65mm T/B underdrive crank pulley was only worth 10hp over a stock 5.0HO. LS1's only make 305hp. That's where they are rated at.

The stock Cobra's dyno near 260hp at the crank. A full bassani long tube setup had Saleen GTS dynoing at 265rwhp on an otherwise stock 93 Cobra. The exhaust is restrictive, the computer sucks, and the MAF isn't a whole lot better than the stock 55mm piece.

If you guys don't know, you don't know.

Hey Dudes!

I'm gonna try better drivng a bit at the track for now, & then see if there's a place locally to dyno my car & see what's up.
I am torn between the BFG's & the Nittos. I went for a ride in my mechanic's '99 Lioghtnign trucjk which runs 11.9's on a 175hp NOS shot & Nitto's. Man, what a rush it is in a 11.9 vehicle!!! WOW! Than 5K lb truck pulled so hard my neck still hurts! I will meet up with Lx mike msometimne soon & we'll have some fun at the track & see what's up.

UNIT: Thanks agian for the replys. I will try to get a dyno soon to see whats really there & let everyone know. Wish you were around here to come have some fun at orlando speedowrls!

EZRIDIN: Palm aBeach is just down I95 from me. In fact, I have an old college buddy who is a cop in Coral Springs so I can get ther noprob & spend a weekend there & we can get to the track at Moroso or wherever is close to you!

sedanman: thanks for the note. I will be torn between the b & e cams so your input does matter! Hope to have one installed by the end of the summer! Will let you know...

Take it easy & thanks all for the replys!
Later!

So Venomous do U think the A9L and meter swap netted U much if any?? I expected to see your trap speeds go up no matter what your 60foot times were. If U had a valve spring break the next two mods I would do to your car would be the E cam and a good set of valve springs! When I changed to my E-cam my car had and still has just over 17,000 miles, I talked to numerous people and they said that I should change my springs even with the low mileage. Do the cam and spring swap and U will be on your way. Besides your average bolt ons only difference in our cars is my E-cam and valve springs, my car shouldnt be 8mph faster than yours, U have weak valve springs I am thinking and that is holding u back right now, heck if U R gonna change the springs though U might as well put a descent cam in the car! Dont worry U will get there! Later!

Thats cool man. I go every friday night. It would be great to have u here. Your cobra is really nice from what you say so i hoep to see it.

First I assume you are talking crank horse power :confused: I didn't know anyone even talked about crank hp on a modded car these days. I expect someone talking from proven hp numbers to talk about it in RWHP. Unless you know guys who pull their motor for dyno tunning? That being said there is no way that combo would make 330-340rwhp, I know I ACTUALLY had that combo and am not talking about a friend of a friend of a friend of a freind.

Well they put a smaller cam in the cobra than they did in the 5.0 HO they also put a crappy computer, hence the only 10 hp gain.

:rolleyes: I have seen several make 305 at the tires :eek: please speak from the real world (like actually seeing the car on the dyno) and not out of your ***.

I beleive it is YOU who does not know, your post usually define stupidity and everyone who is reading this is dumber having read your post, I rest my case and may god have mercy on your soul.
