**SOLD** Benross head (unused)
Turbo Mini Forums

Had this beauty made up by the man himself a couple of months ago.
Fitted it to the car as the final part of a rebuild, tried to fire it up and had to switch out the needle just to get an idle - it flows THAT much!

Anyway, pulled off the drive and went to test it out only to find the gearbox (automatic) had died while the car was off the road. Given the costs in rebuilding them I'm cutting my losses and going 16v leaving this work of art without a purpose.

Spec is as follows:
20.8cc combustion chambers
Fully ported and polished for maximum port velocity and flow
3 angled seats on the inlets, with 1 mm seat
45 deg seats on the exhausts 1 mm
Stellite unleaded inserts
525 fast road double thin wire springs kind to the valve train but capable of 7000 rpm with no valve bounce
35.7 mm inlets
29.5mm exhausts

21 4 plasma nitrided stainless race valves
Bullet nose manganise bronze guides
Dupont top quality stem seals
Hasterloyd inner valve spring retainers

Condition wise it's as new, literally only 15mins run time.
£500

20.8 ?

Yeah, 20.8cc...

Coupled with the pistons (7cc) and the HG (BK450) gave a comp ratio of 10.1:1.

assume this is a NA head?

My turbo head only has 20cc.

In the 13's at last!.. Just

18cc pistons though Gary?

If something is worth doing, it's worth doing half of.

I'm sure Skortchio or Benross will confirm the intended use, however the add does mention an autobox so assuming NA

Yup 18cc's

In the 13's at last!.. Just

Yep, it's a N/A head.
It was used with 7cc dish pistons and a BK450 giving 10.1:1 - according to Mr Benross, he did all the calculations. :)
