Damn, Geno, those are some brutal 60s. Weren't you getting better 60s with the older tires?

Let me know when you get those slicks. I may need to "rent" them from you!

geno5.0 · 07-17-2002, 11:10 AM

Yes I was hooking better with the old tires but I was not shooting a 100 shot before!! I ran 3 passes on just motor and got 2.160 foot times with no spinning this was done with a N2o tune on the motor 9* timing and high Fp I think that if I had it tuned like I did last time I could have hit a 2.0 I also think that if I had hooked up on the juice I would have hit a 12 in the 109-110 Mph range. with slicks I bet its a 12.5 car

89 Cobra LX · 07-17-2002, 11:19 AM

I was expecting 12.5s this time! At least you've got the MPH.

What were you're times and MPH on all motor?

geno5.0 · 07-17-2002, 12:01 PM

I hit two 13.7s at 103.5 and102.6and one13.8 at 101.5 this was with a rich tune and 9* timing if I had A timing light I know I could have hit 13.5 @104.

blksn955.o · 07-17-2002, 01:25 PM

a buddy of mine has a 347 and has the tfs heads and with a port job got 375cfm int. and 325 ex. (the porter wants them back to mount on his wall there the best heads he has ever done) And ther not the new tfs heads there the old 5-7 years old the first ones with out the high ex port. no b.s. If its all out power than id say tfs or afr, if its daily driven with some racing get the gt40s or jr. they have way better com.chambers over stock.

tireburner163 · 07-17-2002, 02:23 PM

he got that that out of JUST porting the heads?

There wasn't any other work done to them?

Your gonna sit there and tell me he pick up 120cfm with JUST a port job?

This good 'ole boy ain't buyin that till I see proof.

Eric4Nitrous · 07-17-2002, 02:46 PM

I'm with Josh..those heads take alot of porting and polishing to get them to flow that kind of number. I'm not gonna call BS but the flag is ready to wave any minute

Unit 5302 · 07-17-2002, 06:53 PM

89 Cobra LX I'm going to do this ONE more time. People wonder why I'm hardly ever on this site anymore? You can't figure out how to get your engine to run worth a damn so nobody can have a good running engine combo. I see.

Let's get things straight. In that discussion we were talking about the GT-40 irons.

The GT-40 iron "Cobra" heads are NOT the GT-40P heads. The bone stock Cobra's dyno about 220rwhp, which is 260hp. A bolt on Cobra with a good computer will make better than 300hp with inferior heads. Why do you think the GT-40P combo is weaker than the GT-40 iron combo?

Central coast rates their GT-40P combo at 320hp. The Stage 2 GT-40P combo from XFM is rated at 325+hp.

http://members9.clubphoto.com/bob425635/guest-1.phtml

www.centralcoastmustang.com

I don't have time to search the web all day for you. There are a couple links, and a couple references. Like I stated before, if you can't get 320hp out of a well setup GT-40P combo, you need sombody else to put together an engine for you. The race guys are trapping 120mph N/A on bone stock GT-40P castings. They are dynoing over 340rwhp. A quick mill of the heads will get you 10.0:1 compression, and their greater compression isn't giving them 100hp.

tireburner163 · 07-17-2002, 07:56 PM

89 Cobra LX, your only trapping 103!?!?!??!

Where did you get your GT-40P's? Do they still have the stock valve train?

89 Cobra LX · 07-17-2002, 08:41 PM

Unit, I never said the original GT-40s were better than the Ps. However the Ps are not anywhere near 40hp better than the original design.

I know what the guys in the racing classes are running with these heads and I can assure you these are not typical real-world results. However, the results they are acheiving are impressive.

By the way, most folks that bought the GT-40 crate motors didn't reach Ford's advertised claims of 280 or 320.

Tireburner, I have stock valves with aftermarket springs... supplied by CCM. Do you remember what the guy that ran a 12.6 trapped? I'm more interested in MPH than ET. MPH is a result of HP. ET is more typically a result of traction.

Compare Skyman and Geno. Both were trapping around 108mph on their runs but their ETs are miles apart.... just like their 60 foots.

Stroked408 · 07-17-2002, 11:02 PM

Where did he get these heads from TEA? Bennett? Please tell me this is an Outlaw car or very minimum a Hot Street/Street Bandit motor?

If no one else will throw up the BS flag I will I know he is not driving this thing on the street,maybe you meant to say 225cfm on the exhaust.

Heck a 3000 dollar Victor Glidden head out of the box flows 365,but you will pay out the waazooo for rockers,headers and the like by the time you are done.

TFS Twisted Wedge is a stout head but it would no where resemble what the original look like with that much port work.

Plus if someone told me a small block flowed 325 on the exhaust,I would build a flowbench just to make sure these are not ringers.

tireburner163 · 07-18-2002, 01:04 AM

89 Cobra LX, sorry but 103 is not a good trap for a heads/cam/intake/bolt on five-oh.

Sorry I don't know the mph. I didn't actully see the time. I'm near sighted, so I asked my brother what he ran and he told me. I asked what mph but they had already cleared the boards. He wasn't really paying attenion, he was watching his friend in the far lane.

89 Cobra LX · 07-18-2002, 08:01 AM

Tireburner, what you fail to realize is that this is a very mild combo (mainly because of the heads). Regardless, a 103.5mph trap isn't that bad. Most stock 5.0s trapped 95mph.... + or - a couple mph. Period.

Skyman was trapping around 106mph with out the box Trick Flows and a superior intake. A whopping 3mph faster than my combo. Does that mean his car runs like crap? I think we all agree he has a strong running car. The videos he's able to post are proof enough.

Anyway, I'm done with this thread. To address the original question posted again, I think it's been proven by results posted by members of this board who go to the track. Go with the p-heads (un-milled) and fight for 105mph trap speeds or go with Trick Flows and fight for 110mph speeds.

Tireburner, I'm sure you'll share with us what traps you hit when you get a heads,cam,intake mustang.

Out.

Stroked408 · 07-18-2002, 08:06 AM

wait a second you went to the track,made a pass and did not get a timeslip?????????

Even ancient Piedmont Dragway in North carolina gives out timeslips.

Hmmmm a drag strip that does not give out timeslips?????

Joe50 · 07-18-2002, 09:06 AM

I know I repeatedly can trap 108.5 on my p heads. No mill work, no port work, straight out of the box from central coast. I'm very impressed...you talk about bang for the buck!!!

blksn955.o · 07-18-2002, 01:27 PM

this is not a street car. it has a racers edge forged 347 crank, oliver parabolic rods, custome JE pistions all ballanced to .002 of a gram. the heads where heavaly ported the bill just for porting cost 6,000 he has 22,000 in rec. just for parts, he blew up his trans just past the 1/8 and traped at 12.4 at 125mph. We raced a 69-70 nova that runs cons.11.16 and not hooking until 7500 in 2nd pulled even and whould of passed if he did not freak out when he saw us and let off . IF I can get his flow sheet I will scan it and put it on here. Im not worried about the B.S. flag most people dont believe us untill the hear others talk or see the sheet, Hell I didnot believe him at first.

HORSEMEN RACING · 07-18-2002, 02:23 PM

Well those are some serious Street Heat heads then that can flow 325 wow.

But the subject at hand and my final post on this matter unless someone strikes a nerve,balance the combo,do your homework,get to the track,take good notes and learn from the guys at the track,after all they are the ones out there running the combos and the numbers.

Mustangbelle306 · 07-18-2002, 02:33 PM

Geez.

I love when people who SELDOM post, come back to the boards in a ball of fire to question the validity of everyone and everything...

DON: Don't worry man, I spent bookoo bucks on my combo, and I haven't even RUN it yet!

Remember who we built these engines for...ourselves

Screw good trap times. I know that I'm not like one of these NMRA racers, I have a pathetically low budget. I didn't even have money to finish the engine (heads) but now I'm gonna have money to tune it properly?? Whatever. Just hang in there, and eventually you'll be pleased with your track times!

tireburner163 · 07-18-2002, 04:04 PM

89 Cobra LX, yes Skyler's car does run like crap, no offense to him. He should be traping much higher than that. Just look at exgmguys's traps off the bottle. He has a simmilar combo to Skyler's and is trapping 112.

Stroked408, it wasn't my car or anyone I knows car that ran. It was just some guy, I don't even know his name.
