7 Q's Which brand drag radials hook better? What size TB, MAF etc...

NYC1 · 03-14-2002, 01:43 PM

I posted this in another forum, but everyone doesn't go there. Thanks in advance for any help.

1. Which brand drag radials hook better? (I have 17 X 9 rims)

2. Do I need to upgrade my TB to 70mm? (don't wanna loose pwr)

3. What size Mass Air? (have stock MAF/Sensor on cold air)

4 Do the rear springs from a 94 Cobra fit a 94 GT?

5. Do high flow cats make an off road exause noticably quiter if at all, and do they slow ET's?

6. What size Cam and Rockers recommended?

7. Would I Need to upgrade stock injectors?

It's a daily driven car.

Well I can't answer all your questions, but I'll do what I can.

You'd probably pick up a few hp with a 70mm throttle body.

I'd get a 73mm Pro-M mass-air

Yes Cobra, springs will fit on a GT

Yes high-flow cat's quitein the the car down. And yes you will lose some ET

A set of 24lb/hr injectors would be nice

Thanks Tireburner.

My timing is at the factory settings. What should i set it at, and how much more would i pick up in the 1/4?

Do you have the iron GT40's or the aluminum turbo swrils? Generally speaking you can run more timing with aluminum heads than you can with iron heads - don't ask me how. I think PKRWUD answered one time, but I can't remember.

Anyways, if they are iron, try 13 or 14 degrees with 92 octane and see how that does for you. If aluminum, try 16 or so. I used to run 17 with my TFS heads and 94 octane with no pinging - ever.

Gains are going to be minimal, but definitely worth it. Maybe 3,4 or even 5 hp, every car seems to react a little differently.

Hope this helps.

If I were you I would go with Nitto drag radials.....I was pulling 2.0 60ft's with a vert with stock suspension.

The BF Goodrich grag radials are good too.

NYC1 · 03-15-2002, 12:41 PM

Will I burn a lot more gas if I bump the timing up to 16 or 17?

I posted a 2.0315 60ft on regular Michellin Pilot XGT ZR's It must have been a lucky launch? I definitely think i'm gonna get the Nitto's

Dark_5.0 · 03-15-2002, 02:08 PM

Thats a great 60ft on street tires My best on street tires was a 2.29

You may want to put some Mickey Thompson ET streets on some old rims....They are the ULTIMATE without going to a full on slick.

NYC1 · 03-15-2002, 03:00 PM

Are the MT ET streets good for every day use, or should I just use them for the 1/4?

Unit 5302 · 03-16-2002, 12:45 PM

#1 Nitto's are generally accepted to hook better than BFGoodrich
#2 No, don't upgrade. There is no need.
#3 C&L 76mm
#4 Yes
#5 Yes, they will soften the sound, ET loss is negligable to minor.
#6 Steeda #19,
#7 24lb/hr would be recommeded if you get a cam.

1. I've been looking for info on Drag Radials also, and I found that BFGoodrich get the best reports. People are running 1.6 60 fts on them and a few guys have gone 9s. I'm going with them on my ponys, but they do make a 275/40/17 for your rims. My son will be getting those tires on his LX soon.

2. I was told that 70mm on a near stock engine is a little too big, but with yours it may work nice. If I were you I would go with 65mm, unless you plan on more mods later, and then I would go with the 70mm.

3. I would go with the C&L 76mm unit, I have heard good things about it.

4. I have no idea.

5. Actually a friend of mine gained a few horse power on the dyno from adding a high flow H-pipe over an off road. His ET didn't change though.

6. I would go with a B-303 cam and some 1.7 roller rockers.

7. Be safe and go with some 24lbs and don't forget to get the Mass Air Meter calibrated for the injectors.

I hope some of my research helps you choose your parts.

Thanks so much guys. Again, it's great to get advice from people who have and know these cars.

I'm going shopping soon!

ThreePonyStable, do you know where I could get reports on the BF Goodrich vs Nitto's?
