DW's (new?) Sierra 3dr YB race car

Re: DW's (new?) Sierra N/A PINTO race car

When I looked into the a 1600 Cosworth would put you down classes anyway, the 1600 would be much better for racing too and would make more power than the 2.0l

You can take the innards out the oil pump and run the standard spray bar when dry sumping cossies I actually have a sump I was going to use on my escort that will fit this purpose as well !

yes it would, although i wouldnt want to face the constant dissbeleif in the paddock though, as the first time you beat anyone they'd scream your cheating

i'd wondered about that, wasnt sure if it would clear the dry sump, sump. i suppose i could check as i have one here

1600 cosworth, Now that is an interesting concept. Never actually thought about doing it.

If your not cheating your not cheating, your engineering to win !!!!!

The Dry sumps dont fit, I have a standard sumpmodified by HT for Dry sump use that I wont be using any more

yeah i know it wouldnt be cheating but everybody would think you were!!!!!!!!!!!!

I didn't think that the cossie head fitted a 1600 block

Dave,
Sorry to see the pinto go, but with the weight saves you've already made you have the basis for a cracking 3dr YB. You don't need big power to be successful in a 3dr as I proved last season in the CTCRC. My restricted Pre-93 3dr ran competitively against some far more powerful machinery in Classic Thunder. It's all about driveablility and momentum!
As some have already mentioned, if you are not restricted by regs then there are far more reliable turbos than the T3 around these days. Careful research and a knowledge of compressor maps should see you right.
Good luck with the build!

up until last year 8 injectors would of put you in class A, but as you say these days it you can get such big injectors that only having 4 doesnt hold power back.

theres no limit in the turbo as such, BUT there is a possibility of turbo restrictors being introduced,

in particular the possiblity of using 34mm ( as per rally cars) which would allow dave to run in a class BELOW the BIG horsepower sierras

Graham,
It would be good if the restrictor was 36mm on the YB as this would commonise the restrictor regs between Pre-93 and DMN. Would allow a bit of cross over and prehaps help both clubs. TTRS also run 36mm.
Thought it worth a mention.

This is a video of me in my 3dr with a GT28RS ex 64 housing filmed by a Escort cosworth with a GT35 I pull out the pits in front of him he passes me as I do 2 warm up laps then I go past him round clearways after I warmed my tyres & pull away from him.The turbo I am looking at is GT30 64 housing called a GT29 by some people & run a large external waste gate which will let it rev higher

Re: DW's (new?) Sierra N/A PINTO race car

Concentrated on finishing the inside of the car today. Have now fitted my new carbon seat that was a TS bargain. Is a bit narrower than the sparco, a little lighter and looks much better in the car in red than the blue did imho

Also finished my new gear lever. It is the one Gary made for the TVR T5 that I had in the escort, so first I had to change the holes as the spacing was different on the tvr box and then I cut nearly half of it off to suit the driving position in the sierra. This is just a touch longer than the type 9 stick was I think.
I got a nylon gear knob from motorsport tools and turned the end of the stick down to 10mm. I have drilled the knob out to 10mm so that it is a tight fit and will glue it in place before I drive the car. Didn't see the need to thread it as it is only one more thing to work loose





I have also fitted a gauge pod and boost gauge that I picked up from Burtons the other day. Is easily visible through the wheel

turbo

dave you just made it more expensive

if you really must have more power go duratec.

bah power mad racers

Re: DW's (new?) Sierra N/A PINTO race car

Putting in Duratec would put Dave in the top class though, as it's a non-standard engine.

[Graham]

Re: DW's (new?) Sierra N/A PINTO race car

new rules for 2010 mean a 2.0 duratec would only move dave up one class,

but it would be expensive, it would be cheaper and probably just as effective to run a 2.4 pinto

Not power mad Duncan, thats why I'm aiming for mid 300's and not 500bhp+..
I wouldn't go duratec as even though it would for now only move up one class I doubt that would be the case if I ever have to race it elsewhere in the future and besides a good enough duratec would still be into 5 figures. Plus a gearbox to take over 230bhp in N/A form is another £2.5-£3K so really its a no brainer now.

Any good high revving pinto based engine will need a steel bottom end, new top end and would still need to be stripped every year as any of our engines are so I'm very happy to go the YBT route, keep it reliable and have a lot of fun racing, plus the car will be a blast for trackdays and testdays as I intend to be able to use it as much as possible once its finished.

Not the pinto verses duratec arguement again, PLEASE

When is the plan to have the engine / car together then?
