What do you guys think Forced Induction 500RWHP VS All Motor 500RWHP. Witch one will win a 1/4 mi race?

both stock bottom end?
can the n/a be a stroker?
if both stock bottom end i think the FI car will win. it should make more tq.
if the n/a car had gears it could use the higher rpms more.

but you have to many different out comes.
which car wieghs more? transmission, gears, tires ect.
you are also asking two different comparisons.
two different ways to measure performance.

Not sure on the winner, but I can tell you which motor I'd much rather have.

I've had a 550+ rwph boosted car and a 550 rwph spray car but never a 500 rwph N/A car (maybe soon, fingers crossed for TFS/HC Combo).

It all depends on what your'e doing to make the power. In my Supra, with a 3.0 I6. It sure was nice to put down 28mpg on the highway and still have 572 rwph when the boost gauge hit 1.8bar.

However, restricted to an F-car or C5/6. I think I'd rather have the n/a power for the sheer joy of not needing to constantly tune the thing.

As always...it would depend on the setup.

I like the way N/A motors run, and I like the way and where they make their power.

At those HP levels, I would have to say that the N/A car would win if all things were equal. If all the cars involved were setup up to get the power and traction to the ground....then I think that the N/A car will make its power sooner. Turbo will have to build...but I think that a blown car could give it a run.

Then again I could be wrong!

I chose N/A. You cant go wrong with a 408 with a huge H/C pakcage.

408, heads, cam, 530-550 witout breaking a sweat. If you are still getting out run by those Supra's, give them a little 150 sqeeze!!! Emergencies only of course!!!

It would totally be dependant on the setups, 550rwhp is 550rwhp with the optimal setup on both cars they will be equal.

id go N/A all the way. 500 is easy with forced induction. actualy it seems kind of low these days. im sure with both having a forged motor, you could swap pullies or turn up the boost, but you can also add alittle 200 shot and get the same neck snapp feeling. i like the way N/A sounds. vicious!!!

It all depends on when each car comes on. It would be my belief that a stroker motor with 550 rwhp will start making power sooner than a stock bottom end with a blower/FI, therefore giving it the win. I choose cubes.

The NA car with all else being equal will be 100-200lbs lighter.

i pick N/A b/c i would assume you would build a motor. and then if you got bored with 500 you could always spray it.

i have a turbo set up and my car makes power right away and can foot break it to about 10 lb.thats 460tq so i dont have to build any power or wait for it NA heads and cam usualy make it at 4300 and peack hp at 6600. so who ever can get it to the ground faster and the better drag set up would prob. win its only a 1/4 mile

The forced induction car would make more torque and have a better powerband than the NA 500 rwhp car, especially if you're making comparing it to a smaller-cube NA 500 rwhp.

Also, the driveability and gas mileage are going to be much higher with a forced induction setup. No big cam to chug along.

I've had both, so I'm speaking from experience.

cubes baby. dont get me wrong, i love boost. especially in the form of a turbo LSX car. but i would go with NA. there is just something bout a big nasty NA motor that gets to me. Plus I love N20, so i'm agreeing with everyone who said spray it if you get tired of 500.

I'll have to agree with Kraest, having a huge cam will wear on you in the long run. Not to mention your gas mileage will suffer If it's a DD, I'd go with the F.I. setup more user friendly to me.

This all depends on what kind of FI we're talking about. If you had a good turbo setup, it should win. The torque curve would be unbeatable, and it would certainly counteract the extra weight and then some.

FI is the way to go IMO. You want more power? Turn up the boost. Bottles are for babies. Real men get blown.

I've been dying for a D1SC for a while now...

You COULD build a 500hp motor... but then think of the posibilities when you'd strap a blower/turbo to it...

06cobaltSS

Depends on the type of FI. a twin screw type supercharger will have big block torque right off idle.

It all depends on the setup...period.

If you have a NA 500rwhp motor where your stall brings you off the line hard and jumps to it's powerband it will be performing perfectly to it's designed specs.

If you have a FI car with 500rwhp and it can spool up and leave the line hard and then jump to it's powerband then it is also performing perfectly to it's designed specs.

Granted, this is in a perfect world and with a lot of knowledge for each setup, if you are just a normal guy with limited resources then yes there would be definite advantages from either setup. This bickering between which one would be best is crazy, 500rwhp is 500rwhp. Just look at the 1000rwhp supras out there running 11's because the guys don't care how it runs the 1/4 and don't set them up to do it.

500 rwhp isnt all that common from a Na engine . I bet their are less than 100 cars on this site make that na out of the thousands here. Maybe 10 are 346 cube . Dont get me wrong as Im not saying it cant be done easy. Most parts choosen by members here will never reach that level . Take terminators car for example . thats a proven close enough to 500 rwhp car and the parts are at a reasonable costbut ,I still see members choosing a weaker head and cam packages.

F.I. is a different ballgame. A bolton car still running stock heads ,cam etc can reach 500 easy . Cant beat going from 350rwhp boltons to 500rwhp in a weekends work . plus mpg stays the same under normal driving .A headed, cammed ls1 or any engine at +14.7 atmosphere will double in power with a turbo . superchargers make +70-80percent ontop of what you have now at that psi .

Pretty good video, first runs in the 12's NA after addition of FI goes 9's .
