Veyron beating mini?

[Renrut]

Would you get 200mph rubber for 16" wheels?

What sort of power would a saab 9000 need to put down to push the air out the way at 200mph? I'm guessing north of 700bhp, I know they're strong but is that do-able in a 2.3 saab engine?

Most supercars need at least 500bhp to pass 200 and they tend to be quite slippery shapes.

[Squig]

700bhp is possible... there is/was a drag prepped 9000 running in that region. Ferkle pointed me in it's direction a while ago... absolutely epic!

[prisspringle]

ps the gearboxes on Saabs really are made out of primula/philidelphia. Don't make me post pictures.

i wouldn't mind seeing some of these pics sorry

That's what i was saying earlier in the thread, you need a good shape car to start with, the biggest problem with hitting 200mph, is air resistance.

OK, I'll add my own experiences into the mix...

Toyota Supra MKIII - you can pick up a turbo model with a blown head gasket for less than £1k, might pay a little more for a manual model, but that's the one you want
Aristo/Supra MKIV 2JZ-GTE engine - makes in excess of 300bhp as standard, opening up the breathing and winding the boost up to 1.2 bar will see around 450bhp. I picked my engine up with all the ancillaries for £750.
£450 for a bellhousing from toyota, plus some appropriate parts (no engineering required, it can be done with parts bin parts from toyota!) and you're at 186mph. Total cost of my build is currently at £4500ish

Slightly larger wheels and a longer ratio on the diff needed to hit 200, but it's aerodynamic enough, it certainly hit 150 quick enough and happily kept up with an Aston Martin DB7 GT V12

Enlarged injectors, a piggy back remap, and rev limit raised ought to get you to the magic 200

[McVities]

the late-model 9000 is quite aerodynamic, there's one in Scotland with a thoroughly tuned 2.3 thats pushing out ~485bhp and that had a GPS indicated 192mph. Given a long enough straight it could do 200.
It did need a pretty expensive gearbox though - IIRC the internals cost upwards of £3,000!!! Which kinda defeats the point of this thread.......

I dont know about a 9000 on the strip but I do know there was a square shaped 900 in Street Eliminator in the late 90's. It had a 454ci Chevy, a blower and enough Nos to keep a denist in Ivory for a year. It ran 8's at 165ish mph IIRC and looked stock apart from the 12 inch wide Micky T's on the back and you remember they are FWD when they leave Sweden. There was also a Swede who ran a Saab bodied Top Alcohol Funny Car that might have been a 9000.

Its a brave specimen of a human being who puts more the 300ft lb of torque through the front wheel. Even on the strip.

That'd be froggy then

What about tyres? How easy is it to get hold of 200mph+ rated tyres? Wouldn't fancy a blow out at anything like that speed.

If you wanted to do it in a mini shaped car we can do some estimates based on aero and what we know of the mini:

Original mini had 34bhp and topped out at 72mph. From that we can work out to hit 200 mph a Mini shape would need around 730bhp to beat 200mph. Might take off before then though.

Something more slippery would be a much more sensible proposition. Something like a 1st gen Honda Insight - only about 300bhp needed to crack 200mph. Quite an easy figure to hit with a supercharged Type-R engine...

[fha772]

Mmmmmmmm Insight Type-R

[jiffty]

wouldnt the mx5 be a nice starting point?

crap mk1 mx5 =£300

windshield off, roll bar fitted and a good helmet bought and your looking at a minimal air resistance. Big splitter to keep the front end down and leave the rear a touch higher when lowering.

Theres your starting point anyway. Then I'd be looking at whether or not twin car engines could go in and if not twin bike engines. I rekon it could be done with some skill. theres plenty of options for breaking 500bhp stock (twin c20let, twin 2.4 saab turbo's etc) but with such a small car i would be thinking more like a pair of busa's etc.
They wiegh only 1050kg and with the screen gone and any crap that isn't needed you wouldnt be looking at a great deal less.

10k = 2.5k for building so what can you get in bhp across two engines with management for 6.5k?

[fha772]

If your looking at the MX5, you may as well do what the yanks do, drop a LS1 and 6-speed T56 in it.
With the right diff, you'll see 200mph, and it might be possible for sub £7, if you get the engine and box for the right money, and you won't have the hassle of twin engines.

This video doesn't really get interesting until 1:07 in:


...or 1 with a Mustang 5.0 V8:

[jiffty]

ugh. so tempting. but im at uni. i need to get these speed demons out of my head!!!

[fha772]

I can't find the video anymore, but there is a twin turbo LS powered MX5 in the US, that is on the road and producing about 8-900bhp, if i remember correctly I think that might hit 200mph...

[jiffty]

haha they must be popular over there. what cheaper engines would fit up to the gearbox they have? im curious to know if the saab 2.4 turbo would or any other easily had power houses? see im thinking it would be a great £999er
