Jacks Cossack Grey S2 Turbo
 

So, after a small migration from over the pond(106 oc) i've decided i might as well set up my progress blog here and do some lovely copy and pasting for the 106oc since im apparently not allowed to post a "item buying only" blog at the moment. and apparently my blog over there is "a complete joke"... probably because its the most active thread on that dead forum anyhow.

so rant over.


The plan is to build a 300-350bhp(not quite bothered really) boosted 106 build. rickyp offered me something i couldnt resist. a full build for his "demo" line at next to no labour charge, few hundred his was just for his time.

so i started to accumulate parts currently i have the following, ill not bother with too many pictures really as they seem to take so much room up!


Shell (Kinda, rickys holding it and spraying it any colour, choices personally will be either Cobalt Blue(106), Imperial Blue(Ford Focus mk1), Arden Blue(Corsa). - £750 will be the cost, i wont add this to the final amount until i actually hand the cash over to rickyp.

Pictures to date, i wont post them all as i'm a massive picture whore as you'll probably see soon enough






























I do have a quaife diff but a friend is collecting that sometime in the next 2 weeks so that will be replaced with a gripper diff.

You will want to change those driveshafts to something better. You won't get more than a few thousand miles from those cv joints even if you're lucky at that power. What mods are you planning to run to get 300+ on a gt2860rs? You are operating way outside its island at over 300hp so it's not ideal.

Also, a pressed clutch cover cannot take 300hp - you will want to change to lug drive. Don't believe if people tell you otherwise...

Rest of parts list look good :) I look forward to seeing more :)

get harnesses :) blue seat belts will just look silly in such a build imo haha

Boosted 106 Project Ft. Rickyp
 

Dunno about parts pal most of its gunna be a rickyp engine build and we'll just see what power it makes mate.

What's up with the clutch? I'm told the 4 paddle will be okay for some low boost(200hp) road use then I can change it when the boost is upped when she goes fully track?

As for the shafts colin himself told me they never snapped a shaft in the 400+ hp one they have only doing drag 1/4 miles. Track/road isn't quite as harsh.

What shafts do you recommend??

Also what do you mean the gt2860rs is operating outside isn't island?


Not running buckets mate nor a full cage till she's fully tracked after then a grand per seat and some nice harness' is what'll happen anyway :)

oh right i didnt know this was seeing the road haha i assumed it would be getting buckets straight away ;)

and clutch wise the plate will be fine but the cover wont be up for the job i what ross is saying

The early atspeed shafts run saxo automatic cv joints rated at 70bhp or thereabouts. I've smashed 2, and Titch three, all with less than 1k miles, and all on the road (arguably harder on cv's than the track as you get wheel slip then traction on uneven surface). Their new shafts are much better. :)

Ref the turbo, I mean it is operating well outside its efficiency island at those power levels. You're generating as much heat as power...

The clutch is fine for 200hp, but that's not what I read above so apologies for the misinterpretation :) its not the clutch plate I'm saying isn't man enough, it's the cover. :)

Soo, I'd be better off selling the V1's and buying some V2's? Might do that.. I'll message someone I know who wanted them see what they wanna do about it.

And how is it? I know loads that run the GT28 ? What else would you recommend? Anything bigger is too much lag is it not

Looks very impressive so far jack :) A gt2860 won't be far off 300bhp anyway.... I'd of thought it would of been good for 280 pretty easy at least, if you want over 300, I'd look at either possibly a gt30 or a td05

What are you doing in terms of Headwork, cams, inlet, boost pipe size, and what exhaust are you going to run/who's it made by?

Impressive so far though mate :)

Ive got a vhf35 turbo on a customers 16v lump, thats on boost just after 3k and makes over 300 bhp

Gt28rs flow well over 300hp so don't worry about that. There are other options but a 28rs isn't a bad choice In any way

Turbo dynamics / cr turbos disagree on the tu engines. You can see on mine it's completely maxed out efficiency wise at 330 ish. This is at sensible losses of course - 300atw or there abouts...

If you want to stay garrett, the gtx's are excellent turbos. A gtx2860 may suit you better. IMHO of course.

What difference does it make what engines it on?? Air is air.. It's not like the TU's require a huge amount of boost to make the power. I said this turbo could flow over well over 300 hp and they can.. It's been done dozens of times.
I didn't say they were the best choice.
They are certainly not a bad turbo to use for 300+hp.

Can get a one in very nice shape for about £300 as well :)

Because a gt28 will make 300 comfortably on a 2l engine. The mass flow rate on a 1600 is significantly lower isn't it. Yes it's been done "plenty of times". I've seen "plenty" of supposed 300atf tu engines. I note with interest many are often <250atw too... I seem to be the only one finding that interesting... ;)

Same with the clutch. Several people say the paddle and sprung clutch is fine at 300hp. That dutch guy even claims 400hp on one.

We agree on them not being a bad turbo for that power though. I found them so good I bought a second after going larger and regretting it :) my current hybrid is loosely based on a gt28 also - loosely. I'm a fan :)

Ross of a 2 litre is making 300hp and a 1.6 is making 300hp they are flowing the same amount of air.... Maybe the 2litre is having to do less 'work' to achieve this but that's not a problem.. Just more boost is needed

Some of the fastest fwd drag cars don't bother making their engines more efficient because it's just as easy and cheaper to wind the boost up to 40+psi.. This is indeed on the opposite end of the scale but the principle is the same.
I agree with the fist thing you mentioned, the turbo will be operating outside of it's efficiency island but that doesn't mean it won't make the power, it will just have to do more 'work' to get there

Also with the clutch's.. It has nothing to do with HP but torque, this is down to what the engine is revving to.. If you have 300hp@10,000rpm this clutch will be fine however if your making 300hp@4000rpm this clutch is no use.. Torque, can't beat it

I think we're "arguing" the same point but worded differently. :p

I would rather run (as I'm sure you would) a turbo at 14psi to get 300hp than 28psi to get 300hp for obvious reasons. And the gt2860's just don't like boost above about 20psi - you get diminishing returns. So yes, whilst the 1600 and the 2l both make 300hp, the 1600 turbo is working harder to shift that air. Are we going round in circles?:p

The gt30 made 300hp at 9psi iirc on my engine - but was a fucking dog. Screw that. The gtx's have filled that void somewhat :)

I stand by my original statement. 300-350 hp, ie, a "real" 270-320atw, the gt28 is not the best choice any more, and you won't get 350hp from one. Well, perhaps on lollers vs rollers - as gibbo would put it :)

Perhaps, you don't work out what HP a turbo can make by WHP or bhp@wheels. No-one does that. The BHP unless engine dyno'd will be worked out differently depending on what rollers it's on as you know so cannot really say this turbo will make 300@wheels or that turbo 250@wheels etc

Also, it's actually better in terms of performance to run a smaller turbo with more boost than a larger turbo with less boost... Check out out mates in wrc/touring cars for that. That gives you better torque.

Agreed. But they don't have the same reliability concerns :p

Turbo f1 cars running mega boost etc - I do know what you mean :)
