Boring or Stroking?

Is it just a Smiley as you give when a serious question is asked? Or do you want to know it is his own custom design to his spec... All questions can of course be answered but please give the same courtesy as you would like to be offered to you. It is an S60R manifold but I think you knew that as you have posted that Volvo manifolds can flow 500BHP.

The point is the others did not spilt though so showing standard liners can take close to 600BHP. A bit more time and they might not of split though.... Only one bore is scored in the picture.

Hello Tim

Not too sure if you got out the bed the wrong side or what your going on about but if you can answer the post please i think we just wanted some facts and details on the car you said about i was showing an interest but you always see it as some sort of attack i guess thats just your way.....

Sorry to hijack this but is it not possible to just add +20 pistons to the 850 block & have it replated?

**Tim Williams** · Wednesday 18th March 2009, 23:25

Yes the standard block can have a +20 or +40 overbore.

Russ you have missunderstood me.

It's a bit long winded but this link has an S60R dynoed with a standard manifold and off the shelf cat back exhaust. It made 530BHP on pump fuel http://www.tme.se/e_main.htm

It was fitted with a Garrett T25 flanged GT series turbo, Im sure you are well aware of it from talks you had with MTE when you invited them over though... Or do you know of others too?

This is the car http://shop.mte.se/

I hope this answers your question, could you now answer some of the questions asked of you?

**marky 76** · Wednesday 18th March 2009, 23:42

just thinking aloud here if there are cars that take the power which the volvo block is supposedly able to handle 500 bhp would we not be looking at how the car is mapped ?? i know theres alot of factors to take into account with engine design and build spec but if this is done to a high spec then is it possible that the map is not quite right , i have seen a map being created on a apexi standalone and it really is a minefield with so many factors etc to take into account like i said thinking aloud

Hi Marky

I still maintain the volvo block will not handle a genuine 500 hp for long
It will work but its only a matter of time before the liner problem happens i first RR my car at 535 without a problem but who's to say the liner had not started to split after this run,there were no other signs of a problem once the engine was aloud to cool for a while i even managed to drive the car home without a problem.

I entrusted my fine tuning of my map to my chosen mapper who is the best in the business at this high level of tuning we had a very mild map on the car it made the power very easily i still have a lot to learn in mapping terms but am very glad i have the best teacher

cheers marky

realised the problem with the 2.5 block i am sure ford have done nothing to better the problem it will be the after market tuners who will take the engine further remember the liner/engine design is only for 300 hp not 600

The problem's are the design of the block ,the liner thickness and the exhaust manifold design.....like all the big horsepower swedish cars they all run tubular manifolds....

IMHO I think you have underestimated the Ford RS engineering teams ability, time will tell

Hi Gary

What have you heard ?

Russ

**Engineer** · Thursday 19th March 2009, 21:22

Its no secret Russ they have just managed to do what Volvo have not hence the 2.4 T5 instead of the 2.5 T5. Nissan are doing a similar thing I believe. Not sure if it will help you though as your BHP/torque goals are a lot higher at the moment. When I get some more info I will let you know.

Oh sounds like they will last a bit longer then,full of info as usual Gary

**PaulZX** · Thursday 19th March 2009, 22:03

so a fair summary would be that, essentially, you can't bore, BUT if you really wanna do it, you can, just make sure you get the old beer tokens out, it's gonna cost a few....?

ok, I'm officially not going there....

Anyone know of a 19t knockin about?

Its funny i thought you were not interested in my little project i am not sure how i missed so many questions i guess its due to people in the volvo world finally seeing someone with some decent genuine power....

I am not sure why you seem to have your knickers in a twist about me all the time i wish all us Volvo nuts could get on but i guess your not like me at all....

Russ

**Tim Williams** · Friday 20th March 2009, 19:32

I haven't got my knickers in a twist but just like honest answers to honest questions. I would have no objection to them being answered on the forum they came from if that's more suitable.

I am interested in your project, I tried to get to meet you at the Autosport show and invited you to the MRG meet.

Sorry Mrs Mopp for bring questions over from another forum, I won't do it again.

Hi Tim

We are all friends here we all share the same love of cars etc

I think you will find i invited you to the Autosport show but you had flu and could not make it which as i said at the time was a shame, i do like to talk face to face and not hide behind a keyboard from what your mates have said you are a nice guy....

**spesh** · Friday 20th March 2009, 20:50

Tim is most helpfull, i dont know anyone with more knowledge then him, he always get back to you if you need info or advise, unlike some on this thread, just my 2p, think this thread is far enough off track now.
ps Have you any vids of your car on the road russ, would be nice to see how see goes.
