20B Build see's the light!

Some of you will have been following my build on my website www.rspowerprojects.co.uk as sadly these days I barely have time to keep that up to date yet alone fill in a forum thread too. Hope mods don't mind. I do pop in to say hi from time to time thoughand check out what's going on. Also I appreciate the info I get when needed. So I thought I would share a video of my project 20B that is not yet on my website! It saw daylight for the first time in a few years yesterday and made it's way to a dyno for a little bit of light setup while I decide to do with the engine.
I didn't really set out with the aim of big power as I wanted to limit boost to 10psi on the wastegate and run maybe 6500 rpm.
Sadly due to being sold a completely wrong spring somewhere down the line the wastegate was only making 4psi! After managing to fudge a bleed valve into the system we were able to get a bit of boost albeit spiking and then not holding very well. but managed to pull it up through the rev range gently to 6500rpm in the end but the boost dropped quickly from 5000rpm after spiking around 4500rpm to around 10psi Peak power was made just after that at about 5600rpm and about 8psi boost. 345BHP at the hubs (circa 412BHP flywheel) which in reflection isn't half bad all things considered! So a bit bitter sweet. Main thing is everything seemed to work okay. Turbo maybe a bit more laggy than I would hope but a bit unfair to judge with the duff setup.

1st run up to around 4500rpm

4th run after some messing with the wastegate to try and achieve some boost!
