Damn. I told you.
Sorry you got wacked

What, for trying to skew the truth?

2SSARME

I knew I would but there's a HUGE difference. I braked right after he started pulling but last night we went again and him giving me a 1 car advantage was a lot harder on him. He pulls me about a bus up top around 150-160mph but before that it's fair game. His clutch was slipping in 4th last night so he wasn't able to catch me on some runs but he made a new 40/60 meth mix with some octane booster and the car was running faster than ****.

I'm trying to get my tuning set and hopefully ill get a few more rwhp out of the tune but I never thought I would beat him. I just wanted to see how I would do.

That car is pretty much the king around here. Like I said he's taken out v10 r8s, alpha-6 gtrs, lambos, everything. One day though I will catch him Maybe it's time to spray but since I got meth and boost spray would be catastrophic.

Get that bitch lighter and maybe with a piston swap and more boost you can do it!

I'm thinking just unplugging the water meth for one pass, adding torco and throwing in a 125 shot.

IMO, there is no shame in losing to that Fox...it looks like a fast bitch

I don't know if that will be enough!

Yup agree-crazy fast car

I'm no nutswigger, there is no fix. I don't give a hoot what anyone says, the sound of the smallblock Ford is much better then the smallblock Chevy. Not that the chevy doesn't sound good because it is sweet, but the sb ford has the sound department in-the-bag.

My brother (Mustang guy) always shows me sb Ford's with small amounts of boost pushing some crazy power. One that I can remember recently was a 347 stroker turbo'd w/ 13 lbs near 1100hp. So you never know.

Didn't the OP say the Mustang was 39x cubes? Could be mistaken, but if not I dont see a 390-cube motor with a good set of heads needing almost 30# of boost to make that number. Also, you have have to consider what blower he is running. So far I haven't heard much of the details on the build.


BUT, I must say this, especially on the first vid it sounded like he was spraying a shot! A lot of guys with centrifugal units will wait until traction sets in and then spray a shot to get the revs up quick! Centri's love RPM, nitrous will get you them fast. I've seen it many, many times.

Me thinks your brother meant "twin-turbo" ... Of course, it may be a big ol' useless turbo due to lag.

Back in 01, we had a car were I was 'working' that made a bit over 1200rwhp... It had a blower... F-3R. It was a 434 and the 95 Mustang GTS it was in weighed 3350 lb and was tagged, etc. It ran a best of 8.25@169mph... on street legal tires. That said, the blower was ALL business and we saw upwards of 28 lb, which we all thought was astounding back then. Astounding that the engine didn't shatter...

383-393. I don't think it needs 28 lb to make 750rwhp. I said it would have that and probably plenty more. It is, in my mind, not going to see 750rwhp w/ 8 lb from a blower and "streetable" compression. I spent a long time building and racing Fox body Mustangs and I've seen thousands of set ups and changes to this or that.

My guess would be he's closer to 18 lb boost in that power range, but the car doesn't actually make 750rwhp... That's BIG power, even today, for a street car. I kinda suspect it's not a 393 either. Maybe a 383, maybe a 408... could be anything between 351 and 434, but I'm guessing 408/10 because those have become very popular. Also, I still kinda do think the car has juice. My feeling is, it's a 600ish rwhp car. At 2800 lb, that's gonna run VERY quickly over a 1/4 mile(or even a mile).

I almost said last night, it reminded me of my own 408 Mustang, as it sounded VERY much like mine. I did the N/A thing, but built for juice. I'd like to know what size that engine is and frankly, to see pics of the under hood area... It's FAST, I know that! In fact, they reached speeds I'd no longer want to reach on the highway, even if it was an area with emergency crews standing by. Fox body Mustangs aren't good at holding the road at 140+mph.

Only on stock suspension. Urethane bushing help a ton, and with stiffer springs and shocks, my fox was as stable as my C5 is. maybe more so.

On the size of the motor and power, there's really no telling. I think 750 is too high for that boost, but there's no telling what boost he really running, what sized power plant it is, etc... That said, I made 762 to the wheels at just shy of 15psi and that was with a 331. I'm proud of that number because even though I don't believe it's anything amazing, it's the stoutest number I've seen at that boost level. Anyway, a 393 built well would do that with a lot less boost - maybe around 10. Then again, I'm running a 76mm turbo, and it should be more efficient than a blower, which should need more boost to compensate.

Chris Arnold

Now I see there's a little history here. OP said in the other thread that he's personally seen the car max out at 8 psi. So, I'm not discounting the possibility that it's making 750 to the wheel, but I think it's likely making less. They are awesome little cars, though, and 650 to the tire would be plenty to get that car into the high 130s. It could also be spraying. What does he use to tune that car? The MSD7531 box, or an up to date Big Stuff 3 with a driveshaft speed sensor would be able to control wheel spin to help it hook up on the street through the first few gears. That's the route I'm going with mine (BS3).

Took to dyno

Car hit 440rwhp@2psi.
505@5psi
600@8psi

Reason I have different psi readings is the belt broke in half on the 2nd dyno run lol. Had to buy a new one and it was slipping when I hit 505rwhp. Finally got it solved and it hit 603rwhp.

This is on timing 19 very detuned.

All I can say is damn. It is going to cost you a lot more $ to beat him. You have to overcome the huge weight difference.

2SSARME

The car is always in the shop. I have seen every single part of the car and ridden in it various times. The guy is my close friend.

There is no shot in it.

2SSARME

Well just look how he pulled me in the videos. I just hit 603rwhp at the dyno. And my boost comes in at 2k rpm, his comes it later since he's running a vortech.

Didnt look like he was spinning to bad in the second vid. You did alot better than expected in that second one.

assasinator

we have a tbird that's been in the rags who runs a 392 and makes 750rwhp on low boost like that. he is capable of running 13psi but that is renegade power and he isnt set up for that. 392 plus Ysi plus low boost = 750rwhp.

guy goes by 392bird on tccoa.


Bruce runs 10.5:1 and uses E85. when a 392 makes 600hp bwfore boost, it takes little to reach 750+ rwhp.
