Turbo Dilema, editted: Solved Twin Scroll BW EFR 7670 it is then.

[punton.bhp]

In my testing and experiance it is the best by far, It is very current tech in it rather than the Garret 10year old turbo with a updated comp wheel,
I could sell anything and moving away from garret was a big change for me as I had blinkers on for years.

Mark

Thanks mark but was I right that you said they are a nightmare to get a holed of ie the 8374

[Sunnysidebb]

Oi Big Frank............ now we have established your going a even bigger turbo for bigger hp are yer going bigger cc's or is she staying at 2 litre ??

No Karl.
my remit to Jim is let the engine produce what ever it can and bag it. If it makes more than 550 safely then i will take it with open hands. If it fails to produce as much as a T4 can max out at then so be it. Were sure the BW will produce much much better power under the curve.

If it all goes Pete Tong and the T4 would have been better out right .....do you know what.......in the big scheme of things I dont really give a shit. Part of the joy of having modded cars is the journey getting to your destination and not just the destination alone.
i will still have a mega good car no matter what.

We did chat about this did you forget what I said,
Twin Scroll BW EFR 7670 nothing else needs to be said, This is by far the best set up full stop but what do I know I have only done 7 of these this year.

Whats would the difference's be between the EFR 7670 and the FMW S300SX that ive got Mark?

The 7670 is about 100hp smaller than the one you have. I should be mapping one in the next couple of weeks.

How easy are these to get a hold of now Mark? Whats the waiting time?

I can get the 9180 hopefully this week and the 7064 avl now, Waiting on the 7670 and 8374 hopefully within the next month or so.

Cheers Mark,

Let us know how it goes

[Mike Rainbird]

So you spent 10K on a engine to spool a 20year old 2k turbonot the best way of doing it,
Also didnt that engine break the nose off the crank and then went on to hole a piston,
So you updated your engine which caused you problems but your turbo was reliable,
Did you know BW are the sole supplier to the Indycar champoinship and this year has not had a problem with reliablity even at the Indy 500 which is about as hard as it gets and the turbo's are production item that we are now fitting to the cars.

Funny how your memory doesn't stretch to remembering the causes (as obviously that wouldn't suit your argument) .

That was Farndon's design of the crank having the oilway drilled incorrectly - it got sorted by them providing a revised crank at cost (not ideal, but at least it was something).

And it cracked a piston due to one of the oil squirter jets failing on track.

Unfortunately, as you know, these things happen. Also, you're forgetting that when I wanted to try one of these EFR turbos, it was the time they were falling apart, so I kept my shonky T4 .

Anyway, irrespective of how I achieved it, you only have to compare the results with any engine of similar power to see that the bottom end response is pretty good? Why not put some Borg Warner ENGINE dyno sheets up of COSWORTHS for comparison, or are you scared that a shonky 20 year old turbo will show up an all singing, all dancing BW item ?

And just like your crank company BW sorted there wheel attachment problem and warrenty,
Not botherd using the engine dyno for quite some time as I found on the standard spec engines it added nothing other than cost, and as I dont use the ND dyno anymore I will be moving on the most likely HT racings dyno or poss Bluesprint when my costomers what me to use the engine dyno,
So no superflow dyno graphs for a while and just a DD RR graph for now.

Jesus every time i think i have found a turbo to use some one puts me off them mark are these turbos 100% worth having before i spent a lot of money on the one i would need is 8374 thanks steven

[turbomook]

I will let you all know what i think of my BW in the next few weeks. Finally my car is running again. Im going to have to get it mapped on my L8 for now, but thats all i can afford at the moment. Eventually plan on going Autronic and letting Mark do his thing.

What power and what bw turbo you going for

[Adamski]

He, has a s300, the one you quoted will do you if its the power you want, the turbos are fine. I'm using mine daily as my audi alternator is fucked no worries at all.

So you think someone's advice who has never touched one over someone who has done 7 this year is better

Where did you get that from? I only mentioned why I didn't use one at the time and just raised natural concerns (just like from my experience, I'd now never use or recommend a Farndon crank ever again, and would always recommend Arrow). I've actually advised Frank by PM that if you say they have sorted the problems to 100% go for it .
