B20 Turbo in 142

Been watching this with interest, but 1 question, what class are you going to run it in? ( as in CAMS) Or is it for track days etc......

I can imagine that it would be fun to drive, yes.

thats amazing Chris, well done! cant wait to see it in action. Great build

The push rods don't look std, what are they from or special order.

Info on kit to adapt gearbox? They make a B230 one?

"353kw at the wheels running 17 psi"

With numbers like that, I'm surprised EVO owners have not converted their weak 4G63 engines to a B20 pushrod unit.

I'm floored!. Who did your head and do you have pics of the combustion chambers?

Just read the thread through, and it is an awesome build.
Has it seen a track yet?

Wakefield once i think and not very quick

I remember a blow up about this around a year ago on iroll, lots of people skeptical about the 353kw @ 17psi

Yeah,the usual suspects...it happens if it was posted at 253kw or 153kw.
The owner knows,who can dispute it? Nobody unless they are there.

No, it wouldn't happen if posted at 153kw. 353kw at the wheels is approx 406kw at the flywheel or 540hp.

That's more power than a C190 AMG GT 4 litre twin-turbo or about the same as an R35 GTR 3.8L twin-turbo.

Just how much airflow do you think a non-cross flow B20 with a single tiny throttle has compared to the above engines? Maybe it was running at 14,500 rpm. LOL

The common occurrence on any dyno post is a whole lot of negativity....

Believe what you want but theres laws of physics that dictate a pushrod non crossflow 1960s tractor engine cant approach the volumetric efficiency of a koenigsegg or modern supercar.
Theres no doubt this is about as nuts as you can go with a B20 and whatever the actual figures are its an impressive result
