ST150 clutch fits, when he FRP's clutch neds changing i'll be going for it, got a stiffer feel to the pedal aswell which I find better...

 

[PumaNoob]

Im not too sure on all the issues that have made peoples engines blow, ive seen a hole through the block where a con rod has gone through the block, but i dont believe that was due to the rods being weak, i think it was oil surge, so that piston and rod werent getting any or enough oil, ive also seen a hole in a piston, but again, that may not be due to weak pistons, it could be that the engine or one bank were running too lean, or ignition timing was out. I think Madhillbilly17 might no more as he did some research when he was building his.

Thanks! I didnt know you were back on here? There you go then, the ST150 clutch fits!

agree...

who has gone beyond 230..anyone on here.

Im not sure if he was on standard internals or not, but there is a guy on here called "Bouncy", i think he was getting more then 230bhp at some point, using the standard manifold too, but not sure if its still going, or if its all finished now or what, he had a project on the other puma forum.

been back for months mate

with plus 200 bhp[ will an st150 be good enough though, i really need a damn good cluytch...nothing worse than losing popwer through a slipping clutch...

 

[PumaNoob]

Its not bhp that will make it slip. An ST150 with 200bhp will be fine with standard clutch, because it will probably only be running 200nm of torque which is only around 150 ft/lbs. Yours will be more like 270nm or 200ft/lbs or more, if you reach anywhere near your goal, youll be looking at 340nm. You can try it, but my opinion would be that you need something uprated. I dont know what to suggest if you dont want an aftermarket clutch, other then to change to a focus 2.0, ST170 , or Focus RS box, but they have the starter on the back of the engine not the front like the puma, so youd have to work something out for that! The bolt pattern is the same though, and it would allow you to fit a bigger clutch, an oe focus rs clutch would work. Youd need a flywheel to match too. Id just go with an aftermarket clutch, well, i say i would, i already have!! Quaife do a clutch thats being used in all the bigger power ST150's, its a 5 paddle, but its not really harsh like a 4 paddle. Its £430 from jamsport. Thats the one ive fitted.

 

[paulob1]

okay high quality aftermarket it is...will fit one to nitrous too, bought a 5 paddle but the ruddy thing got soaked in oil when the crnak seal went, this cleared up alright but then the hydraulic cltuch sctuator failed again and this has soaked it again so will change it this time...

the uprated box sounds good but I suspect I will break the engine before the box...I may be wrong...

thanks for all this is helps a great deal...

 

[paulob1]

going to see an escrot cosworth tomorrow to add to the list...heavily modified, know the guy who built it and he has spent a small fortune on it...will be a good play thing...

however I think I will always prefer my frp's. Fun yet sensible enough to not scare you too much...even with turbo and or nitrous..

 

[PumaNoob]

You are INSANE!!!!! How can you possibly do anything more? I can understand having totally different types of cars, maybe a small front wheel drive car, a rear wheel drive car, and a sensible car! If you have a project on, surely if you work on something else, its time that you could be working on the 1st project!

Im just jealous, if i had the space you have, i know for a fact id have at least 5 cars!! I had 5 at the start of the year, but got rid of 2 because they were pointless having, and were taking up valuable drive space!

I had a similar thing with my break pads, i brought new pads for my car, and dropped one in some oil, so had to go and buy more !

If you fit an intercooler, and omex before it blows, then i suspect the gearbox will be the first to go. A lot of modern cars like mazda 3 DISI Mps, and Subaru run high compression with a turbocharger. It makes them more responsive and better on fuel, so if you mapped yours righ, you might get away with the high compression. With that and a T25 on full boost, youd be looking at major power, im not sure what would give up first. On mine, its the gearbox that worries me more then anything!

 

[paulob1]

hmm I must admit the gearbox going was my real worry but we will see, i have a few boxes and a few engines so playing is about to happen...my man is back in new year who is a real enthusiast with these so may get him on board working for me...he can help me keep on top of the projects.]

I went out in the cossie but what a hard car to drive, it was either producing 430 brake or non at all, nothing inbetween, fantastic grip and very nice car. will try a few more first though. And i have to sya no where near as sure footed as the Puma...

 

[PumaNoob]

The problem with a lot of big powered cars with older turbos is that they have just had big bhp in mind when building, but a small 4 cylinder engine like a 2.0 (in the world of engines with tall block V8, V10, and V12s, a 4 pot 2.0 is quite small), if you want major power, you normally have to sacrifice drivability, because you need a massive turbocharger that wont kick in until 4k rpm, even as high as 6krpm. Thats a hell of a lot of lag, so fine on a straight line with a rolling start, but unless you can keep it in the very high rpm all the time, you can get caught out. I prefer to sacrifice bhp figures for a drivable car. Heres a vid of me racing a 430bhp sierra cosworth

Its got nearly twice the power that ive got, but there is just too much lag, so he doesn't have enough track to catch me up. on a rolling start, he would have easily beat me, but immagine this on a small track. He would just get further and further behind!

That will be the good thing if you can keep the T25 on yours, it might not get to the power you wanted, but you will have the power all the way through the rev range!

FML!! lol nice one mate!

 

[PumaNoob]

FML!! lol nice one mate!

I must be getting old, what does FML mean??

 

[Zara]

lol don't worry mate I only found out like3 months ago or somthin lol (F**k My Life )

 

[PumaBen]

My Stage1 T3 is good but find mine laggy in first. Once into the revs and changed into second she is spinnig up a goodun. Saying that, that could be down to my accelerator cable being slack and in need of replacing. I'm upgrading to a T34 next year with a -247 maram shaft so can run anti lag.

 

[paulob1]

hmm thats really cool indeed...I would doubt the escort with 430 bhp would keep with my turbo puma either...the drop in-between the gears was humungous...am still thinking I will get an excrot cossie just gor to find the right one..and likely I will be happy with 350 bhp and a driveable car... but i wont lose the love for the puma

 

[paulob1]

well I have had time to look through the paperwork provided by the guy I bought the car off...initially it was producing 147.9bhp, not as much as an FRP..in 2002...in 2003 with a few tweaks this was improved to 160bhp it was supposed to be increased to 165 but it could not get there on 5psi. I was told that running 9 psi it reached 195 bhp but that dyno chart is not here. I will test it and see, this makes me suspect that it is only running about the same as my nitrous puma 180-185 and no more......so in real terms I have a way to go to make this car reach 250bhp. and be driveable. ho hum...more to do...

 

[paulob1]

oh and the compression was reduced to 7.5 to 1....

 

[PumaNoob]

7.5:1 is very low for only 5psi, but at least your set up to run decent boost now, and at least we know why its not blown up yet!!! 7.5:1 must have about a 3mm decompression plate, so you would be able to see it if you look where the head joins the block, if you cant see it, they might have dished the pistons. To get 250 will be a lot easier now, you wont have to take the engine appart, unless of course you want to!! Just an intercooler and injectors and an ecu! Sounds easy when i say it like that. Id be tempted to try fitting slightly bigger injectors, and an intercooler. TGhe standard ecu will self learn to a certain tolerance, so if you went up about 40cc (if we could find out the flow rate of std injectors), i think youd have a very easy job on your hands. The standard ECU would fuel it pretty well, and probably reach your 250bhp mark. It wouldnt be perfect, but you would have a lot better base to work on!

 

[paulob1]

that was my initial thoughts too...interesting that it never quite managed to achieve 165bhp as they claimed it would. It says they used a machined plate so agree it should be visible...

I THINK I will fit an intercooler, first, check on performance, then fit bigger or different injectors and see where that gets me...each stage I will dyno her...it also shows that a lot of work was done on the suspension too with different upper and lower links...all very interesting...this car had a lot of money spent on her...

 

[madhillbilly17]

what a strange thing to do, to go to the trouble of lowering the compression to up the boost but not fit a intercooler :shock: but its great news for you that its been lowered will save you sometime and money was it put on the rolling road with 5psi on std compression or lowered? just wondered as it would give me a rough idea of my bhp at the mow..... do you know what cams youve got?
