highest bhp per ton.
bi22le - 24/2/10 at 10:50 PM

ok so i thought the black and white indy with a turbo zx12 was the most i bhp per ton at 550. The vids on you tube of it look mental. But i have just seen a post from someone stating there fury with turbo rotary power is 600 bhp per ton. Anyone beat that? I really want to see you tube track vids aswell.
Long term i would love a 500bhp per ton car. One day ill build one.
I also dreamed about going around the uk circuits and breaking all of the lap records, less likely i think!
So proven high bhp per ton figures and looney track vids please!


daniel mason - 24/2/10 at 10:53 PM

i think the new caterham v8 levante is pushing 1000 BHP per tonne! it has a price tag to match though!lol


bi22le - 24/2/10 at 10:54 PM

ill set the bench mark.
My striker when i get it will be a very reasonable 280 bhp per ton. There are vids of it chasing an elise on the tube.
280 is about average i think. Zetecs and small becs are about that.

I've seen a dax rush Hayabusa turbo which had something like 350 bhp which would give it over 700bhp per tonne

it was pretty quick


eddie99 - 24/2/10 at 11:06 PM

Think its the one your talking about, Paul Fishers old MK, it lives a mile away from me. Its insane!!!


roadrunner - 24/2/10 at 11:09 PM

There is three BEC turbo'd sevens in CKC mag this month, the least powerfull is at 550bhp a tonne and the others had 350 at the wheels.


austin man - 24/2/10 at 11:10 PM

I believe MK sprtscars have supplied a turbo'd Hyabussa which is around 480 BHP now that got to be in excess of 1000 per ton


bi22le - 24/2/10 at 11:14 PM

it may of been a dax. The guy is on here. His name has just come to me. Its indy bird.
I need to get ckc mag it seems!
Maybe people should state the engine and car aswell. The one above looks like a cossie or zetec turbo. 560 bhp per ton hmmm fun times!

when i win the lottery...
i'll send my engine to norris designs for the 650bhp 500lbft conversion.at 620kg's it should be up there and still cost less than 30k.actually i probably wouldn't,jag xj220 would be way further up the list,then 6r4,audi s1,f40....


rickys2000 - 25/2/10 at 08:34 AM

297bhp and 700kg whatever that works out to be...


alistairolsen - 25/2/10 at 08:35 AM

fficial " target="_blank">Hahlin7

510bhp @ wheels (probably 550+ @ Fly)
720kg

~770bhp/tonne


sprouts-car - 25/2/10 at 08:39 AM

What about the twin engined ultima:
http://www.zcars.org.uk/ultima/index.htm

Weight: 980 kilos
Powered by two turbo charged Hyabusa engines giving 1000 bhp
Power to weight ratio 1020 bhp /tonne


bimbleuk - 25/2/10 at 09:23 AM

Well my Striker at 565kg and 270BHP was just shy of 500BHP per ton. I never realised the potential in the engine but its sold now anyway.

The replacement is at best 1100 kgs and starting with 380BHP works out to 345 BHP per ton. So quite a reduction.

Does have double the torque though and plenty of potential in the engine.


jollygreengiant - 25/2/10 at 09:46 AM

Ah I shall do it diffferently, 2.0l/boat anchor


graememk - 25/2/10 at 10:37 AM

well i have a indy so it dosnt matter how many bhp i put through the back wheels the fronts still wont self center......


INDY BIRD - 25/2/10 at 10:53 AM

Hi all

yep the zx10r turbo is ours we run 9 psi to get the 550 bhp per ton,

we could potentially run a bar of boost which would see well over 600 bhp per ton but we keep it at around 8 - 9 psi to keep it reliable and safe will bags of power,

also yes we a have a dax turbo that is around the 380 bhp mark and @ 550 kg but bags more torque,

anything around the 500 bhp pet ton will be seriously quick car and you need to be a competant driver to get the best from it, and quite deep pockets

i know of several cars with alot more bhp near 500+bhp busa rushes so yes near 900- 1000 bhp per ton thats insane and expensive, f1 performnce apart from the down force,

cheers

Caparo T1 575BHP, 475Kg (dry ...with no driver)

PWR 1210BHP per Tonne


russbost - 25/2/10 at 11:27 AM

"(dry ...with no driver)"

Best thing for a Caparro - saves frying the driver!


I would point out that you all seem to be missing an essential point - the ultimate power/weight is completely irrelevant if it can't put the power on the road.

My original twin engined Furore was 274BHP in around 600kgs so around 450 BHP/tonne but because it was running 11" wide wheels & 285 section tyres with a pair of engines sat straight over them on a dry road there was barely any wheelspin & it would out accelerate almost anything. The other thing to consider is driveline losses - as i had no diff, & chain drive, flywheel bhp would be quite close to roadwheel bhp, with a typical car box & diff setup you will lose around 15 - 25%, so again unless you're taking bhp at the wheels the comparisons are meaningless.
All IMHO of course!

Perfectly valid point but far too sensible to post on a car forum!

My Striker had peak torque at just below redline (centrifugal compressor) which at least made it possible to put most of the power down away from the line.

My RX7 with almost 90% of peak torque from 2K RPM (V8 not a wankel) may be a little more difficult to do so even with double the weight above the rears.


bi22le - 25/2/10 at 01:22 PM

^^second that valid point^^

I was wondering just what the max people had seen. The other thing I was thinking was have people seen super light cars with a moddist (500bhp!!) engine or a heavy car with ludicrus power. ie a 1000bhp supra or 1200bhp skyline would be around a 100bhp per ton. They would get alot of the power down though!

This leads me on to my thoughts that if you have made lots ofpower you really need mid engine to get it down.

It seems there are alot of mad powered cars out there. Any one recommedn any good vids to proove the speed?

Radical SR8LM Lap Record at Nurburgring 6:48 sec proof enough?

I didn't realise that Toyota Supras weighed about 10 tonnes

iank - 25/2/10 at 07:27 PM

Most (aka almost all) 1000bhp cars have a measurable eph (engines per mile).


bi22le - 25/2/10 at 08:00 PM

phah typo helfire! Thats a big supra!
I have watched the sr8 ring lap. Thats some gutsey driving. Love the way he skins a sl amg i think on one of last corners, like it is stand still!


iank - 25/2/10 at 08:11 PM

For a test of grip how about an ultima doing 0-200mph-0

Exactly

m hoping to squeeze somewhere between 250 and 350bhp at 800Kg. Could go even more and go for 480 but im not sure i really need to, or have the money to!

At maximum target, id hope to see 437.5bhp/t, but if i do go for 480 then it will look more like 600bhp/t (with the help of Top Boss Performance).

- Hence the change for the cosworth V6.


DRC INDY 7 - 26/2/10 at 07:26 PM

yes them mk haybusa turbos that were built for a guy in spain yea they were fast and it was bloody cold day


procomp - 27/2/10 at 06:47 PM

Hi

Complete waste of time in most cases as most seven types are struggling to put 150 Bhp down to the ground with any efficiency. Never mind trying to put stupid amounts of uncontrolled turbo power down.

Proof is in the pudding. Mega turbo average kit cars doing lap times barley any better than 90Bhp locost race cars and being slaughtered by 160 bhp 750Mc kit cars and RGB cars.

Whats the symbol for banging head against the wall. Lol

Cheers Matt


turboben - 27/2/10 at 06:50 PM

My turbo kit car puts down about 300 bhp without too much fuss. Certainly wouldnt want less.
