What was the result? good power and torque?

Whats the spec of your car alex?

Spec is:

1275
std cam
std rockers
belt drive (timing not set acuratly!!)
t3
2" stainless system with maniflow down pipe
Green air filter

Only mods are:

Morspeed St3 head
CR 8 - 8.5:1 (depending on how far down the pistons are!)

On 8 psi of boost on a stinking hot day in the afternoon I got 120 bhp at the fly (90 at the wheels) and 150 lb ft of torque!!

The cam is holding the engine back there is SHED loads of torque between 4 and 6k so its possible I have slightly retarded cam timing.

The RR operator was Stuart Gurr at Vmax Scart in Molesey, London.

that sounds very good mate. ive got a phase 2 in mine so hoping that may help. Only on a std head though at the mo, thats first in line for a bit of tweaking. Hoping mine is going on the rollers within the next month. really want to make it to combe in october.

The head is were your power is!

Guess who I continue to recomend!

i can guess mate although im not going there, MBE is my choice , helps only being 10mins from work.

we all know a good head is the key to a lot of things

one bit at a time though. low cost is the key for me at the mo!!

It was for me too... hence std engine!!!

And it still makes 120 bhp on 8 psi.... It will run 10 psi and with roller rockers that should be about 140

Suprising what they'll kick out in a good state of tune. Its all about having a healthy one rather than really high spec a lot of the time within reason of course

Im hoping for about 120 at the flywheel on about 10psi. The head and CR is my limiting factor at the minute so cant go over 10psi comfortably. probably wont even go that high, may stick with 8psi.

150lb ft?

Power sounds reasonable, but that torque seems very high to me for that boost for that boost/CR combination...
Have you calibrated your boost gauge???

Sorry, that came across as really negative!!!

Lets get to the bizz.
How does it drive now? Hhow much torque did it have when you drove in, compared to when you left? etc...

You've told us the 'scores' but little else!!!

WEll I havent driven it before the RR...

last time I drove it was on a std un-set engine on track in november!

It absolutly fucking flies in compairison now!!!

boost guage is a good make and was calibrated about a year ago, apperently I got it off a good mate FOC.

The torque is very high, which is why I suspect retarded cam timing... it gets to 4k and the power just sits there all the way up rather than peaking (as it usually does).

"absolutly fucking flies "

Good Evaluation LOL!

wheel spins a plenty

and chases westfield magebusa's

I have video, will post in a few days

Team Racing

Chases???

chases as in keeps up with?
or
chases as in goes the same direction but only accelerates half as quick

I know which my mini would be...

Well the megabusa was out on its 1st trackday on a very short and twisty track

Home advantage I think

Alex

That is impressive then.
I got my ass well and truly wooped by a Caterfield with just a 1600 cvh on webers when i did Anglesey last year, on the corners and the straights... 'only' 120hp was the answer when i asked him about his engine... and with a stock bottom end, mildly ported head and 285 camshaft, i'd believe him...

I think those 'busa' caterfields will be quite a lot quicker aswell...

been on the track a few times with westfields etc they take some keeping up with

Everyone knows that instructions only have to be read if the thing doesn't work....

Dave, my Grandmother could whip your ass in her 1100 hydroelastic clubman on drums!!

Try a 1500cc hayabusa Radical, now that thing made me look like i was standing still!!

Edited by giallofly on 9th Aug, 2004.

They are fast but you have to absolutly SCREAM the engine to get any power out of it and on that circuit I doubt he had the gears for it...

were as I had the torque and much more track time than he did :)

Not really a fair compairision but funny anyway!

alex

AlexF

I have to dissagree, i have driven a bike engined caterham and they pull from fairly low revs, 4000ish till 12000. The 1300cc suzuki hayabusa is a favourite as it has bags of torque pulling from low rpm, Only problem with the busa is breakers charge the earth for them as they are not that popular.

I looked into buying a Kawasaki ZX9 powered machine, an awsome bit of kit even though it has only 900cc of internal comustion area.

On the subject of torque, when i worked with the Royal engineers i had a drive in a Cheiftain Bridge layer, they are powered by a 19 liter 6 cylinder, 12 piston (you read 12 correctly!!) with a supercharger the size of your average washing machine!!

That 60 tonne beast had a lot of torque!!!!

Hell mate well done on that torque:)

As you know i've had my car now a lot of years and i've been well into it for a few. And i would only have that sort of torque on around 15 -17 psi. What am i doing wrong?? Please help.

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?
