Great, thanks Martin.

I wonder what they might make with a new exhaust as well?

 

Does anyone have anymore info on this new turbo that's being talked about. Thinking about changing the turbo on my spec c and would be interested in some more info.

 

Speak to Iain or Powerstation, they'll tell you all you need to know

 

Better to redline her then?

TX.

 

I wouldn't say all the way to the redline, but certainly a few hundred higher than peak bhp.

 

Liam was that the new car of yours parked in the back of powerstation I looked at last weekend or is it another one from Ian that you are getting?

 

I think you will find that the turbo in this application was around a long time before the MD321 and was based on the original Type25 turbo.

Ilya,
We did a lot of testing in conjunction with PowerStation / Litchfield on our Project Spec C, twin scroll wise, but we never got round to testing (which was then offered as a package) the 400bhp turbo discussed here.

The turbo we ended up with was a Hybrid by Turbo Dynamics and was very good.

The Project Spec C engine is currently running in excess of 500bhp (Cosworth engine 2.5ltr - Single Scroll turbo), which was developed between PowerStation/Litchfield and turbo supplied by AET (along with help from a number of other companies). Full details will be available soon on this Stage3 Modification on ScoobyNet. May give you some food for thought in the future! I have better lowdown grunt than any of the 2ltr twin scroll set-ups gave me and peak power past 7000rpm. The best of both worlds.

Good Luck!

 

That was one was sold a few days before I went to look at it, but the buyer has now pulled out and the car has been re-advertised on his site. Spoke to Iain this morning and he said there has been a lot of interest in my car, so I may well end buying that one rather than waiting for another to turn up at auction.

 

Very very interesting, so single scroll turbo gives more low end? It due to the fact it is now 2.5?

 

It gives me more low-end with my package..... I am not suggesting that this is norm with any package though.

If you have a 2ltr that is already twin scroll and you want up to 400bhp... stick with twin scroll.

Whilst the Cosworth engine is a major part of my build, there is certainly a lot more to the build which helps achieve this power band. As I said, full details will be published very soon.

I believe PowerStation/Litchfield are having another open day very soon..... the Project Spec C will be in attendance during this day and I maybe persuaded to take a few people out for a "gentle" passenger ride.

 

Most Twin-scroll turbos will outperform their single-scroll counter parts, all things being equal. The problem has been that there are relatively few good Twin-scroll options. Powerstation’s current 400bhp conversion uses a Hybrid turbo built for them by Turbo Dynamics that installs a much bigger Garrett core and Compressor into the original Twin-scroll exhaust housing. This takes a LOT of specialist machine work and is why it is so expensive. We have tried a number of other options but they did not work as well as this on the 2.0 cars. It is very rare that you can change nothing but the turbo, go up a size and not lose something lower down.

We are working on a new Twin-scroll turbo option at the moment as Martin has said but it will be a little time before we have done enough testing to switch to it

A lot of things will affect how the turbo respond and you need know how each person’s engine will differ. Shaun’s Type-25 engine may displace 2.5 litres but the short engine and compression are different to most, the Cosworth cylinder heads and valves will flow more and even the CAMS make a significant difference to it’s response.

 

Thats very exciting, what characteristics are you trying to achieve with the new turbo? The ultimate twin scroll with both low and top torque?
I'll take two

When is the open day, I would definately like to come by

By the way Iain, I have spoken to Rich earlier this week about a possible Turbo Dynamics hybrid turbo installation in my car like the one discribed in the article. After a brief conversation I send him a short e-mail with a list of what I already got and was told I'd recieve a quote for the job including the price for parts I will still recquire, however haven't yet got nothing back. I am not in a rush, but really do think of having the job done by the end of Feb, so maybe you could slip a little reminder for me. Thx.

 

Pretty much, yes. I shift between 7800 and 8000 on mine. Torque really starts to drop off at 7800 but the main reason for a just-before-the-redline shift is not fluffing it and hitting the rev limiter!

 

any news on this?

 

I hope this will lower my MPG, it's getting in the 20's far tooooo high


You'll have to give me a quote for 400+ as i love hotter summers

Tony

 

Tony your doing scoobyshootout arnt you? if so you can have a little drive in mine to see what the differance with yours is if you want Im away as car 12 just look me up I will be in the pit area somewhere.

 

yep i am going but me and the car are a bit lardy so going to get my 4rse whoopped

I'm number 32 and would love to take you up on offer you can have a go in mine perhaps swop LOL

I did take one of Iains Type 25 cossys out, now that was special although the Race Scoob @ donny now that was something else.

Tony

 

No problem Tony see you there

 

cant tell you my registration it might get cloned, you might have a guess though

Tony

 

Its alright Tony I will just look out for the number 32 which will be plastered over the middle of your number plate
