Horsepower battle isnt an issue against those 1000+ whp "Slutra's". Also, have you keep forgetten weight difference? Those pigs are at 3250-3350 while I'm floating at 2750-2850. Hmmm, lets see if it evens out now.

Anyone knows a supra that willing to run? I got my RX7.

the engines seen 9,800 on the dyno(just graduated from s.a.m.).....


n-e ways,this car is a bench mark for all street-drag rotaries.oneday i hope to make that much power.

crispeed,have you ever seen numbers that high out of a s4/s5 block,on c16,without tearing itself to shreds?

mcnannay

Just out of curiousity why is a s6 block so much better? I think i would prefer the oil injection of a s4/s5 rotor housings over the s6's. I always thought a s5 with fd corner springs would be a kick *** setup.

Don't want to get too off topic, so ill say that is a kick *** car, and i would love to see it in action.

not this tired crap again

are you really the owner of this car? if so, it's almost sad....

sorry to burst your bubble, but the relatively minor weight advantage you have over a Supra will help you very little at freeway speeds, esp as you near triple digits, where hp and aerodynamics domnate the equation

more people on this forum need to take a basic physics class, I swear

monster city rx7
does ur car make 600 rwhp?


congrats to crispeed and v8 killer. very impressed

MARTIN

What numbers has it seen??? all you talking about is rpms, and Ipersonally have seen higher rpms... Stocl block

n87

Congrats to you for an awesome car. 600HP is a very sweet number. However, Motorcity RX-7 is right about a 800-1000rwhp Supra smoking your car at speed. Either way, your car will smoke 99% of everything on the road. I feel like my 400 at the wheels is puny.

MARTIN

The supra is not the most aerodynamic car, so dont come to that... The rx7 has aerodymics and weight on the supra...

Next person to talk about how good their V8 3rd gen is will be the casue of this thread getting locked

Dont make me go through the whole thread to remove your posts that are not relevant to the topic at hand, there is a V8 section on this site where you can all go make love to each other about how good your cars are

Dont be like a mormon and come to my door and tell me **** I dont want to hear !

You already deleted every post I had.

follow basic rules, dont turn this place into a **** fest Note for you LT1RX7 since you missed it in the last posts here and on previous pages.

V8 KILA

your the one who sad...did you even read the article you sent me? I suggest you read it again, if u can read, especially about rolling resistance & drag. RX7= less weight & better aerodynamics. What makes u think the supra has better aerodynamics then the rx7? the car is higher, wider and fatter. I guess you need to change your avatar sign. "For a 3000 pound car these equate to roughly 35 and 50 pounds of force at 30 and 70 mph, respectively. Under inflation or excessive weight increase tire rolling resistance considerably". & "It is generally accepted that, on a typical car, its rolling resistance and aerodynamic drag become equal at about 50 mph. So at twice that speed the aerodynamic drag is about 4 times the rolling resistance"

Exhaust sniffers on freeway entrances? Ive never heard of that, not even here in **** NYC.

First let me say congrats on the numbers. AWESOME car!!! However, I don't think you are understanding what he posted and what you read. You pretty much just showed us in your post why weight isn't as big a factor at high speeds. At 50mph, weight plays an equal roll in determining acceleration as aerodynamic drag. Anything under 50mph, weight plays a higher roll. At 100mph, aerodynamic drag is 4 times more powerfull a force to overcome...thus weight still plays a roll, but horsepower vs drag coefficient is what really makes the difference. A Supra's drag coefficient is .32 vs the FD's .29, so not terribly too far off. I'd say your weight advantage and better aerodynamics will allow you to run even with a 750whp Supra...beyond that, I would think the faster you go...the more the higher horsepower Supra has the advantage. Don't sweat it though...there aren't really THAT many 800+whp Supras roaming the interstates every day.

V8 KILA

Thanks, I appreciate that. Isn't amazing how many people have so much envy, especially when you have what they can't? This thread wasnt started to compare to supras, it was to inform everyone who loves rx7's that what can be made with such an unrated and unrespected engine. If you love supras, then go get one...better yet, join the supra forum and stay off this one.

Motor City RX-7

I'm not envious, really I'm not, I like my FD the way it is, about 380 rwhp and full boost at 3800 rpm....but you stated that your FD will blow 800-1000 hp Supras off the road, so I had to throw the bs flag

carry on....

Old Slow Coach

V8 KILA, I'm curious about your hp and tq graphs... would your set up allow you to tune for more hp/tq earlier in your RPM range? I wonder if maybe you had decided to produce less so that it would have certain performance characteristics. Compare your graphs with the attached... see here at 5250 this guy has about a 100 hp/tq more than you. Could you tune yours this way if you wanted to? Or is there something about your set-up which would prevent a similar graph, and what might that be?

ghostrx7

Yes but in the 1/4 mile rx7s generally get better 60 foots, with that said, I dont think hed have a problem running one at the track and winning. Depending on tire / set up.

Motor City RX-7

the context was freeway racing at high speed, not the drag strip....of course the drag strip is entirely different story

ghostrx7

Im not saying a properly modded supra wont beat him on the highway, I am merely stating that, in a street race/ drag race, from a dig, he would do fairly well.

MARTIN

This is something that this forum fukin suffers from... speculation. Everyone goes out and plots the races before it happens... Power is not everything and just because theres a supra with 800hp doesnt mean that its gunna automatically beat a 650hp 7. I seen it many times, where the win goes to the lower Hp car.. Gearing, tuning, and power curve, is most important and then comes body drag and weight... A car that in 4th can make flat power band all the way to redline means that it has an advantage and most likely the win, against a car that makes more power but does it all at the end... If you look at the 4th gear graph, its very flat, and that is a killer.

And again, congrats to the owner, and to crispeed for the awesome tunning.

I think some people in this thread are overestimating the effects of aerodynamic drag. It probably takes about ~130 hp to sustain a 120 mph cruise, so in the case of 'V8Killer's car at 120 mph the % of his power expended to fight drag isnt as big as you would think (since he has 600+?). Of course the power expended due to drag goes up with speed cubed, so at 150mph that number is probably closer to 250 hp, but again thats a lot less than the total power he has available for acceleration. So, I guess the point is that when comparing the top end relative accelerations of higher horsespower cars the speeds at which aerodyanmic drag effects are more important than the power/weight ratio become higher (thats obvious I guess too). Were not talking about 250 hp cars here. Its not like once 'V8killer's car hits 'triple digit' speeds that drag will dominate. At 150 mph, it will start becoming important, but if you want to race at speeds over that shouldnt you get a Supra?

Arent there quite few high horsepower Supras in Miami for you to meet up with? I'm sure in a 40mph to 150 mph race this FD would do VERY well against most of them.
