The engine is almost complete & today Mark was sorting out details to allow swift change over of 2 turbos , 2 manifolds, 2 inlets & 4/8 injectors.
The Dyno is now booked for 2 maybe 3 days so we can really find out what works best with what.

aduz

should go well in a straight line

Mark Shead

Yes it has.

Good luck to you and Mark

Mark Shead

Yes part of the testing is 2 diff turbo's with a total of 4 combinations/2 exhaust manifolds/2 inlet manifolds, 4 1200cc injectors and 8 750cc injectors the hope is none of the manifolds are better because the inlet is around 3k and the exhaust manifold is the same ,
Some of the testing will be keeped secret and we will prob only let out the max figures as the testing of all these parts is costly and I belive I should be the only one to benafit from it .

is there a reason for choosing the 2wd head mark? i was under the impression it was prone to cracking because of the chamber design? not a dig or anything, just curious as i was going to sell my 2wd head for a 4x4, but if it's okay for big power, i may aswell keep it!

glancy2081

thanks mark thought a was seeing things at first are these tests just to achieve max power or to see which has the longest power band

Mark Shead

I have used both types of head and found no diff in power or reliablity.

Don't suppose this car does 200mph does it ?
























Obviously won't hear the figures which is fair enough but you are certainly going to town on what works best.

Fair play and good luck

JonnyBravo

Now that is interesting, what do you know about cracked 200 blocks Mark ?

awesome, cheers mark

Mark Shead

Both manifolds are split pulse as is the exhaust housings on the turbo's, The first black manifold works well but the second white one is a very new desgin which I think is better so its the best opportunity to test them.

Mark

Mark Shead

I know that the later blocks have had core shift and this has made them weak over 92mm or very high power on smaller bores,
My contact at Cosworth says they are looking to make new blocks/head but the time scale is unsure but I would guess over a year.

Mark

JonnyBravo

Thanks Mark

boXXer

Looking good buys

BTW Mark: Thanks for helping me with my car that night i phoned you about my yellow injector being stuck.

GARETH T

i would love to help you do the testing

Rick

me too lol

smitsturbo

ok so say all goes well & the right parts are picked when can we be expecting this all bolted up and running again mate

Mark Shead

Before TOTB

Mark

smitsturbo

nice, i hope to be there as a witness

Dingy

Big blower on what looks to be a standard engine LOL...

Dumped's engine pics are interesting this is more of 200mph boredom

Kevin Atkins

I think Mark may surprise a few people on the handling circuit at TOTB, Rod's car ain't slow round corners.

Rod,Mark,
cant wait to to the results.


Dingy,

You are indeed a cock

Dingy

its a saff ffs

Dingy

yeah and you don't answer anything but abuse....FACTAMUNDO....

Rod-Tarry

215 hopefully dingy & with a 10s quarter to boot, all very boring .

Big Will_

Wow - looking good.

Had a quick chat with Mark the morning before Time Attack Silverstone and he said things were moving on with yours

Which turbo is that in the pics? GT4088? GT4094? GT42R variant?

Looking forward to the dyno figures all the same - best of luck

Dingy

each to there own mate, terry's mk 2 does 10's fast car, faster than yours and doesn;t interest me.

Good luck with it.

Maybe I'm a tool too but if I bolted a big turbo on a Godfrey design manifold on any engine in my workshop then it would look the same... for once in Dingy's life he is right!!

Having said that Good luck Rod, hope it works for you

Mark Shead

Wrong the manifold was made and desgined by PD and this is not the same as the one there made for JG several years ago, and this one was made/adjusted to what I wanted by PD ,
One day we may see yours run at full power but I do belive its been 9 months running on and off seems to me you are scared to run it at full power, Do you think the head will come off
