should be doing Gurston down and castle combe too later in the year which are closer to you than the others, september and october iirc

Still going to be out my way in September?

awaitin entry confirmation in next week or so i guess, will let you know :)
confirmed for Anglesey sept 1st/2nd (iirc), Prescott (nr cheltenham) sept 22nd

Cool, I'm sure I can make it along to one of them. Prescott looks promising, it's only about 60miles up the road.

It's also one of the better Hillclimbs for spectating.
I'll be there (silver & black SS1), come and say hi :)
Cheers, Raz

Sounds like a plan :)

confirmed entry for Gurston Down too on sunday 9th september

ok sorry to bump old thread, but season is now nearly over (just Castle combe left on oct 20th) and i realise that i never put up power figs even though a few asked.
spec is as can be seen in the earlier pics, basically forgies, steel rods, lightened + balanced everything, autosprint cam, CNH Diy headwork, cut'n'shut DET tubular manifold with external wastegate and turbo technics T28 hybrid.
engine made 282bhp and 266lb/ft at 15psi boost :cool:
have the printout from Dave Walkers Emerald dyno (PPC mag tech guy) somewhere if anyones interested.

impressive figures Craig, similar to what I'm going to try to hit but with a few different methods. have you got any idea of the spec of the autosprint cam? I'm chatting to them at the moment

not idea on specs really. i took geoff (Mr Autosprint) a Piper one and he based his 'special' on that. it has an asymetric profile ans the one side of the cam lobe is flat. a trick from some of his ford cams apparently. works great tho, breathes much better at high revs but then so does the piper.

That is a very impressive figure at that boost level on a t28 hybrid. Well done. :cool:

I have a piper at the moment and its extreme to say the least but I want to try other things too :) i'll have to compare my graphs to yours if i ever get the engine in a car

Well done getting that figure with what some consider low boost :D :D:)

i just think all the mods are well matched hence the 'low' boost. i think that turning the boost up another 5-8psi wont make much difference as i think the 8v head design starts to become restrictive as S13eater forund out, probably just raise charge temps a fair bit. Great on track though:cool:

How did you get on at the last couple of events? I didn't manage to make it to any of them in the end thanks to work and other boring things! :rolleyes:

cars going ace to be honest, main problem now is traction even with the softest List 1B tyres on the market:rolleyes: 5 class records in last 5 events and think ive wrapped up the Super modified class championship as well:cool:
dont really know what i can do to improve things now as more power wont help, and suspension setup is pretty well maxed out for the class so maybe have to look at a different championship or move class. there is talk of handicapping my sort of car (an SS1) further to slow them and im not really interested in that. Will have to wait until mid november to see what new rule changes are voted in:rolleyes:
Just castle combe left this year, so lets hope i can finish on a high

well done craig,;)

What have you done suspension wise to it craig?

cheers S13Eater :)
30psi
from std or from last season?

Well in general from a standard car. Also be interesting to know what the geometry is too :)

Well done for the results! You'll be at Castle Combe on the 20th? Again it's not a million miles from me and I'd like to come and watch (assuming someone doesn't need me to help them move house or sort their car for an MOT :rolleyes: )

Do you have any restriction on Aerodynamics in your class?

from std its got shorter AVO coilovers with adj spring platforms on the rear with uprated springs (std car has coilovers but not adj or adj platforms). its semi'trailing arm suspension which has to be retained due to the regs (cant change to dbl wishbone etc) but its rosejointed for toe adj. Rear disc conversion using wilwood calipers and pads (not needed previosly, drums were fine upto 250bhp). rera roll bar adjsuatbel with rosejoint droplinks.
front end has rosejointed lower arms and polybushed uppers. std car has springs between the wishbones but pushrod dampers, so ive stregthened upper wishbones and fitted coilver springs and dumped the springs between the wishbones. front dampers are trick AVO dbl adjusted with custom valving.
car runs approx 2.5 deg camber and zero toe. thicker anti roll bar with rosejoint drop links.
front brakes are large-ish grooved AP race discs with AP 4 pot mega light ally calipers and choice of Mintex or Pagid carbon metallic pads.
most of our guys that run in teh lower Modified class run stiffer springs front and rear and AVO or spax dampers and the cars are really good on road tyres. mines had to have more done because its not a compromise (super mod class), doesnt get run on the road.

Cheers craig, thats cool that it has double wishbone up front as standard. Do the rose joints make it much noisier/harsher?

Why have you opted for zero toe?

yeah i shall be there, just hope its dry coz the cars crap in the wet! at Combe i hit over 140mph and with semi-slicks and standing water you can hear my bottle rattling over the exhaust note! if you pop along come over and say hello.
yeah the aero is governed by the MSAs Modified Production regs, so not a lot of leeway. basically you cant do anything more above the centreline of the wheel nuts :rolleyes: , but im working on a few bits for next season already ;)

That's fair comment, the start and finish "straight" is bad enough in the dry let alone when you've got puddles to contend with. At least the field should have been harvested by machines other than cherished racing cars by now so if the worse happens then at least you could find your way out! ;)

I'll defo come and find you on the day as it'd be nice to put a face to the name and finally see your car in the flesh!

Silly MSA, they are always spoiling peoples fun! Looking forward to seeing the car develop over the winter already :cool:

car nor face are pretty mate :eek: both are showing a few miles and battle scars lol

Mod Prod is reasonably restrictive re aero, but Sports Libre is much more liberal but then you have to fight with single seaters and GT cars (V8 darrian etc etc) :( better to stick where i am i reckon lol

tyres are shagged (only last a season) so just dont want standing water, or else its hello gravel trap...

yeah dbl wishbone setup at the front, actually vauxhall chevette. Good ol scimitar factory parts bin car design lol.
rose joints do make it harsher, i dont think id ever use them on a road car suspension. wear rate and dirt ingress gets to bad for a road car. I like polybushes for road cars, firmer without removing your fillings and still hugely better location the rubber bushes-Yuk!
Scims have zero toe as std, but to be honest ive tried toe in and toe out. toe out gives better turn-in but makes inner tyre shoulders overheat as they are really running too much negative camber when you add the dynamic camber in (camber change thru suspension compression). it also makes the car wander a little at high speed too, but not a major issue.
car runs better .5 and 1 deg of rear toe in too to make the car stable.
