Got to give mark his dues he's the only tuner that comes on here and gives free advice

turbotrev

Very true. Totally agree

Cheers Paul

turbotrev

A few tuners are very helpful and interested on the fb pages.
Both Harvey and Mark are two of them.
I think a lot of tuners just don’t wanna get involved with some of these discussions and debates these days, I don’t blame them though tbh

thats unfair ,but probably true rich

how much?

It seems Smith and Jones machine the blocks, but they are actually made by Granger and Worral, has anyone purchased a finished block direct from the foundry?

If I ever get my single seater finished then a 22kg weight saving will make a big difference to the YB going in it.

Caddyshack

I doubt Granger would sell direct.

stevieturbo

I'm sure anyone going to the trouble of developing and producing such an item would have tight contracts in place.

I remember tuna wars well lol

steveboyslim

Thant is not correct, Granger & Worral cast the S & J blocks and heads, they originally did the machining but it has been do in house at S & J

Which is what I wrote?

Looking back at an old thread on here from round 2012 Steve, you stated that Smith and Jones claimed these blocks were not suitable for big hp turbo application, what changes have been made to the alloy blocks since then?

Quite important if someone buys an earlier block thinking they are all the same

Caddyshack

I assume the bolts through the main caps help with high boost?

Adam-M

Lol was thinking that myself

PAUL S

iTrader: (8)

Which would make sense, but I can find no info on their website that restricts big hp turbo engines to only the through bolt application, in fact I was unable to find any reference at all to that ability?

smiley

Ive only heard of rainbirds chucking a rod anybody heard of any other faliures? These have been around a good while now running turbo with the older design charlie shaws would be an older one surely running his level of power for as long as it has shows thier capable of handling big hp big boost + nos

Jay,

fucking lol but let him be a know all fuck all it's fun Paul

FLAT TRACK

Mikes wasent a alloy block

smiley

I hear from sombody on here he had one built the build was on escortcosworth forum now sold the rolling shell to sombody on here

FLAT TRACK

it was a iron block

smiley

Thats even better then only faliure ive heard of maybe misunderstood as was 2.2

Caddyshack

They have not updated the site at all in ages, it was Mark Shead who told me they had improved the block for the main caps and that was some months ago. As I understand it you can only buy the main caps one now.

I have not seen anything about the ally not being for big turbo....I do think that the block was probably originally cast with the Naturally Aspirated Rally boys and I think the Ally head was designed for this....almost to cash in on a Millington Diamond alternative? I am frequently wrong though.

steveboyslim

The pattern work for making the castings has been altered to enable a thicker casting where it is required to enable a much stronger finished cylinder block, SCS have had direct input to the modifications required and I believe Julian Godfery also had some input.
The block now has head studs running the full height of the block.
Whilst they have had their problems which is only to be expected given the amount of power obtained from turbocharging their engines, they have proved to be much better at dampening the harmonics and other forces which crack the iron block even with liner conversion.

Steve

smiley

What problems have they had steve? I believe some big power 200's run harmonic dampers so that sounds good

steveboyslim

Physical strength issues as originally N/A as already stated, not turbo and only to be expected, head lift.

Get one built lad

turbotrev

I believe Dave Pritchard had a problem with his alloy block...

I’m unsure of the exact issues though

im thinking about it

turnover

Tbh if your fitting a ybt as long as it’s built correctly,and more importantly TUNED correctly you can run 500 to 600 hp on iron block reliably,which in any car the weighs round 1300kg ain’t slow,but if your not bothered about putting jap in your ford go f20 out of Honda S2000 standard engine unopened will support 600hp when turbod,again with a proper tune ,cheapest way unfortunately is none ford engines these days

smiley

True mate but if youve specced 500-600 thiers quiet a jump in cost from 500-600 500 can be ran on std internals 600 cannot limit of std rods around 550 im told then thiers long studding/liners this is were you start to see the s&j vs modded 200 cost evening out

turnover

Hmm well I’ve built a few over the years and other than rods and pistons ,good balancing head work and specked cams I’ve ran in my own cars 600 plus hp ,no liners used,but these days everything is getting too expensive on the YB,just depends how deep your pockets are

smiley

Does cost prices crazy now im no builder mate just done my home work and made a few mistakes along the way buying shit and learned the expensive way lol i leave the specs to the pro's and go with what im advised im sure others do things different ways and get results they want but paying out so much will be done once for me i wont be risking it and will play safe how long did your 600 hp last and if it failed what failed? Midlands i am too been around a long time what cars were these maybe seen them

Edited as im a blind cunt and just looked at your sig links lol just back from 10hr drive awesome motor that mk2

ajamesc

I’m the same bolting an engine together is not hard I’ve built enough of them working for daf lol. But I’m after a certain amount of power and torque and it needs to be able to hold together. To get them numbers is where the skill is as it’s not just a case of opening the burton catalog and saying I’ll have that that and that lol. It’s very very expensive so it can only be done once and for me I only intend on doing it once. I’m happy to take the advice and go with what I’m advised as I know I’ll have what I’m looking for at the end

smiley

If mine does go bang that will be the end of it all james lol thats why im im being so cautious in my aproach i do get that if a pro specs you an engine their reputation is on the line also and ofcourse they will play safe and if building yourself all you have to lose is money when it goes wrong but the advice im following came from two of the very best imo its a shame one is no longer with us god rest his sole

turbotrev

You can run a lot more that 550hp on standard rods buddy, closer to 700
is more like the limit

Cheers Paul

turbotrev

Spot on

Cheers Paul

Lol and lol again as the forum requires more than 3 letters..

I'll leave to the pro's mate as ive said i know fuck all just that i trust the advice im given
