Last night there was a big cruise in at the Dave and Buster's in the Cincinnati, Ohio area. There was a guy there claiming 600 HP (didn't say to the wheels or through the flywheel) on a T-88. I was just wondering if it was possible to have even 600 HP though the flywheel on the stock 13B motor. He was wanting to race anything for pink slips too.

 

umm...I don't think so on a stock motor. Maybe bridgeport but I doubt on a stock ported motor. Could be wrong though

 

forcefed7s street port w/ t-78 put down 653 non corrected hp.

 

You got a link to that car?

 

OH yeah, he was also wanting to race for 100 MPH to 200 MPH, I didn't think the FD was geared to go 200. Can anyone tell me otherwise?

 

This guy sounds like a nutcase, but yes 5th is setup to go a tad over 200 mph at redline.

 

17" rims, and factory redline of 8K with stock 4.10:1 diff comes to 215ish.

18" rims get you another few MPH.

Now if his motor was properly clearanced & ported he could try to pull past redline...

 

I saw the gear ratio's a while back (maybe on the Lightning site) . I think the 7's are geared for 187mph(standard) and 196mph( Automatic). Don't quote me though. A 3'd gen will definitely definitely do that type of speed with the right amount of hoss. I've had mine to 178mph, but I couldn't get past 150mph until I reached the top of a hill. I still had room too, so they might be able to hit the 200mph mark.
This guy might be telling the truth. But I don't know man. Anyone that's driven up there knows how scary it is. It's an amazing rush though. I pussed out, and I love speed. He must have some brass ones if he's telling the truth.
Most likely



Ask to see a time slip.

there is an article on the peter ferall website saying that he had a customer car up to 630 rwhp. I can't seem to find it, and I am pretty sure I am not making this up . I don't know if that was 93 octane gas... anyone have a link to this page?

 

215? Damn. Impressive.
How did you come up with that figure? It's strange that 4:10's on an American car mean you top out at 110mph. Why is it different on an RX7?
Jim

 

no ******* way way you're gonna make over 600whp on pump gas. you can't even get 500whp on it.

 

Actually I just looked it up from an xls program that Blake Qualley sent me a year or two back.

I don't understand what your saying about 410s topping out at 110. I just looked at 8K RPM, with 17" rims, & the stock 410 diff ratio. The actuall MPH ASSUMES you have the hp to push it that fast.

 

FD,
Isn't that supposed to make 600rwhp? It's advertised as such on RX7.com. Well at least they used to advertise it at that rating(I noticed they took it off over the past year).
Jim

 

ES,
Mustangs come with 3:55's. The other sets popular sets seem to be 3:73's and 4:11's. It seems like most people, with the exception of the hardcore guys, do 3:73's. Cobra guy's seem to do 4:11's, because they have a sixth gear, and can still not wind on the highway or roadcourse for that matter. When they change their gear sets(to be better in the quarter) they always lose top end. This is true especially in older muscle cars, as every once in a while you'll cruise by one on the highway going 60, and he sounds like he's at 6,000rpm. You probably know this already and I just suck at explaining it.
Basically, what they gain down low, they lose up top.
That is why i'm surprised that the rx7 can still do 200mph with 4:10's.
I know someone will come and explain this better than I. Where's the guy who ones a Cobra as well. He'll know.

 

The fd's that are hitting 600 HP, is that on or off the bottle, and what turbo set up? That guy last night was off the bottle just to let you know.

 

it'll make it on race gas. for the amount of boost it takes to make 600rwhp, you will detonate on pump gas.

 

There are two limitations on hitting the magical 200 mph mark. The first is gear limit, the second is aerodynamics. In the super tuner shoot out the PFS turbo 3 rotor (600 HP) couldn't even make it pass 150 mph with a 15 mph head wind. Unless there is aome extensive aero body modifications, the standard FD will not do 200 period.

 

a 100% stock FD can run to near 160. I understand gearing is a limiting factor, but with 600 horses, they should have hit that limitation first.

 

Ok the reason american cars cant break 120 on 4.11 is because american cars redline at 4-5k rpm. With an 8k redline even with the same rearend ratio and 5th gear ratio u can go atleast twice as fast right there as long as you have the right amount of power to push it...an fd definately has the aerodynamics to go over 200...im not sure about the gearing though, as you can see from the rx7.com website: http://www.rx7.com/cgi-local/3catalog.cgi?cat=2&part=6 at 7500RPM in fifth gear with a stock 4.1 ratio ur only going 182 ( i say ONLY 182 because its significantly less than 200, not cuz its slow or anything) so im not sure that in the remaining 500 rpm you can pick up 18 mph.....either that...or im like completely and totally wrong :

 

The top speed of any vehicle is a funny number to begin with. The absolute top speed is usually recorded in a windless condition and near perfect flat run with no length limitations (run till the road runs out). That's why top speed runs usually takes place on the salt flats. I agree they should have at least past 150 but the fact is that they didn't. Neither did the super charged C5, Renntech stage 3 turbo 911.

 

rim size has nothing to do with the top speed.

its about the tire size.

 

So to sum it all up a 13B with a T-88 can't push 600 HP nor go 200MPH correct?

 

yes it does
