just heard that there is aparantly a 500bhp roo in the st austell area does any one know if this is true?

David_Wallis

if there is.. why isnt it entered for ten of the best?

Senior_AP

More pub figures. Anything above about 370 is bollox.

Nathan L

Really? So what about this car?

Pavlo

lol, yeah all pub figures mate.

except maybe........

SJ_Skyline

.....last seen entering an expanse of water?

Senior_AP

Rebuild every 1000 miles.

I mean a real car that is usable. That has been done to boast. It won't last 5 mins will it. Alot of power I must say though.

andykidman

What about a certain STI Wagon, as featured in Japanese Performance, that makes a healthy 585bhp??

callum Sti02

I assume from your statement that you know a bit about the car? Care to fill us in on the detail? I'm specifically interested in how you know Haldor's car will only last five minutes. My guess is you haven't got a clue

andypugh2000

And fangoria's sti 5 is 400 ponies and going strong every day

These outstanding results were, I believe, on a special map using race fuel. I also believe (as hinted) that at these extreme outputs the engine will not last long and Harveys monster has sadly expired.
It just shows what can be achieved by someone willing to put their £££££ into getting results.
I am waiting to see how long the current 550+ BHP 2.3/2.5 litre engines last. Its asking a lot (especially in £) to get these figures from a small engine so it may take a while to work out how to get it "reliably" !!!
Meanwhile I'll make do with my 430BHP daily driver and hope that at that power it lasts - and meanwhile dream of a reliable 600 BHP!

You might want a chat with MarvSTI, cos when his beast comes out of scoobyclinic u might well want to retract the above statement,

riffer

Well I believe folks that the japs say that anything over 320 bhp, the alu head cant handle it, and is more than likely to fire itself thru the bonnet of ya car!!!!!! Bit of advice taken from a jap, who uised to work for da Scoob'Boys.!

Markus

I think there are a fair few cars running around, quite happily, with 320 - 400 odd bhp, but as we all know it's not really the bhp that is the killer it's the torque (unless I'm on planet mad all of a sudden).

A Type 25 puts out around 350+ bhp and 356+ torque. That is probably with a conservative map, so it would not suprise me if you could very easilly, with a slightly more agressive map, get around 370 - 400, all in a pretty reliable way. From what I have heard though, you'd probably not need that much.

Oh, also, EVO had a piece on PPP+ type scoobs, and I seem to recall the RCM car had around 437 bhp and was said to be rather reliable too.

But hey, what the heck do I know about anything lol

riffer

then surley they`d need to be fitted wit a steel head rather than an alu head????????

370 i dont know anyone with a 370bhp impreza not

Bob Rawle

Not sure about cornwall but there is defo one in that neck of the woods, 2.2 litre jobby.

bob

gadget daz

that's right bob, frequently visits bruntingthorpe with rcms and you i believe, owner is a very nice bloke
My rcms/bob rawle 437bhp monster is still running very well as EVERYDAY DRIVE. It is sat outside my work as i speak

this is the car that evo did 3.9 seconds 0-60 and 19.8 0-140, there is no way this car can be over 280bhp cause it is very lightweight at 1650kg.. ....must have been a lucky day with no heatsoke, LOL

Just to put the records straight, i think you'll find nothing wrong with harveys old engine, swapped to closed deck block i believe for even more progress

..........yes, that's right, NOT PUB TALK, evo tests were carried out at/by millbrooke


Darren (proven performance, not pub talk)

David_Wallis

Shut the door behind you.. Dont believe the **** someone is telling you.. as you dont know what your talking about.

Ps I have / will have a fair bit more power than been discussed in this thread.

Thought all scoobs were over 370 BHP !!

Surely if the head lets go it will go out through the inner wing not the bonnet? Obviously know a lot about boxer engines!

The pundits are out again. Pity they cannot get the facts before passing comment.

Stan: My open deck 2016cc 585bhp/464ft.lbs engine is in my garage. The turbo is in Canada for a couple of updates and you can buy the complete engine with warranty if you make me a sufficiently tempting offer.

With Optimax and N.F. this engine did 499ft. lbs at Prosport at a RR day earlier this year but we could not get a BHP figure because of problems with the rollers.

This engine was built in March 2002 by Matt Clark. In October 2002 it produced 417bhp which I think was a record for a Scooby at a UK RR Day at the time. It produced 450 bhp at G-Force a few months after that and last Autumn it produced several runs in the 570-590 bhp bracket with a 585bhp at another RR Day. Again as far as I am aware a record for a UK Scoob at a RR Day.

From the rebuild, the car was used as a daily driver and did 35,000mls approx. but I think I had reached the sensible limit with that engine. It was removed by me in April in advance of the new engine which will have several advantages over the previous unit but is marginally smaller capacity. (+.25 instead of +50) The target is 600bhp/500ft.lbs when fully developed which might take until Christmas, maybe longer.

The car was a daily driver and will continue to be so with over 600bhp. It was also tractable, pulling strongly from 1700rpm in fifth and normal consumption of 17-24 mpg on the road but down to 6mpg on the track. Tickover was smooth at 850 rpm.

Many have been passengers in this car and can confirm the drivability etc.
Independant performance figures: Scooby Shoot Out 2003 when the car was only around 500bhp. www.geocities.com/harveysmith3000.

I have just finished work on my second car a 95 WRX Wagon, again in silver. Bob Rawle is coming up this week-end to check the map and it will go on a RR Day 4 July when I will be disappointed if it does not have 400 bhp. and drop the 1/4 ml from 13.99 well into the 12s.

Some cars may be undrivable and many are unreliable, 2.0, 2.33 or 2.5 but if it is done properly that will not be the case and this 370bhp business is totally wrong.

wall

Back in my wrx and then STi days, when I lived in Australia (98, 99, 00), I spent quite a bit of time at various events talking to the Rigoli boys. For those who don't know them ... makers of a number of well-under-10s scoobs that also go around corners.

Well their philosophy was:
- up to 350/380 - reasonably easy and reliable / drivable
- up to 450/480 - big money and possible problems if not done to perfection
- over 500 - huge money and huge problems likelyhood, good only for showcase or dragstrip scoobs mostly.

There is a reason why all "istitutional" (those who offer serious comprehensive long-milage warranties) upgrades on these cars, be it Prodrive or Ralliart for Evos or even Lichfields and the likes, never really go beyond 350 for both hp and torque ... (see T-25, WR1, Evo340, and the likes).

and then theres others whos engines broke due to user error

we'll see what happends when I try this race fuel lark

Hi Harvey !
My very positive comments were made based on what I had heard on and off the various BBS's ! (so they must be true ! )
Glad monster #1 is OK and #2 and 3 are progressing well.
So was the 580 BHP achieved on a dedicated race fuel map ?
Hope to see results of your latest monster soon.
Stan

Harvey wasnt it??

The real weakness in high power Scoobs is the bearing size which is potentially too small to maintain the required oil film once you get decent torque through it.

Pat did some calculations a while ago and suggested it would be marginal.

Rigoli reckon that once you get into the higher levels of power the bearings need replacing after twenty or so drag runs...

...however they are running over 1,000bhp - which must be a lie of course as the heads wont do over 320bhp

On a more serious note - over 500lbs ft on a Scoob bearing is potentially very close to the margin. High power, especially higher up the rev range is no where near as damaging as the low down torque.

Rannoch

PS Always wonder about these comments of high power cars costing huge amounts of money

PPS Wonders about what fuels were used at Prosport - some had orange tail pipes, some emissions caused serious hallucinations, some merely killed the local wildlife
