going back together







back on nearly ready!

Cool project! You have done mega work. Strange that a ball bearing turbo died, one hot shutdown shouldn't have done it. Why do you have a second restrictor on the oil feed? There is a restrictor in the turbo body. Make sure that you aren't starving it of oil or you will kill another turbo.

[Thealastair34]

thanks, i dont have a second restricter just the one screwed into the turbo core, the fitting is just a -4 90 swivel that goes onto it?

[Thealastair34]

new parts today

oil cooler that im going to run water in for the turbo



fittings for the setup



had a bit of a mare getting it all sorted, the new cooler is going in front of the oil cooler as im more concerned about water temp over the oil temps as they have been too low if anything

ive had to flip the oil cooler over and move it back towards the dry sump tank then weld some tangs onto the chassis to support it



both in there roughly



mounts welded and cleaned up



primered ready for painting

[RalphyBMW]

Very tidy work!

[Thealastair34]

both coolers fitted properly after painting the mounts



pipe work all fitted and hard pipe from aux water pump all secured properly





boost hoses on checking for room if any left!





feed and return cooling pipes fitted to the aeroquip fittings





nearly finished just some tig welding to be done which i cannot do puting the -6 items on the ends of the alloy water rails



adaptor for feed into the top rad hose, need tig welding up but nearly there with it

Looks good, just need some half decent weather now!

Yep although ill go out what ever the weather last time it was snowing haha

got rolling road in 2 weeks on friday so hopefully all will be good for then

[Thealastair34]

- 6 fittings welded onto the water pipes for the turbo cooler



Installation finished







Think I've finished cramming it all in for now



Had abit of hassle bleeding the turbo cooling lines but it them all working now seems to work fine, have no leaks and temps and pressures good.

Need to road test this week again then ready for mapping Friday all being well!!!

[Thealastair34]

been out for road test everthing good!

tomorrow is d day again mapping in london, hope everything goes well this time as im fed up with problem after problem!!!

will update as it goes along, not due on roller till after 4pm

[Thealastair34]

fogot to update this thead, 

 

car going to dyno

 

 

strapped down, 

 

 

 

mapping was done at track n road in essex, i know the guys there well and have allways dynoed my engines for me be it in the car or on the bench.

 

had afew issues on the day and had the boost controller fail so we didnt get as good result as we could have but ill go back at some point to have it perfected i think. 

 

results were good for the boost pressure, 335bhp and 262lbft were the highest seen at around 1 bar engine has plenty more to give but the gearbox and axle dont so power capped to that for now

 

vid here

 

 

graph

 

 

 

 

car is driven on the road only on low boost so far as i want to get used to it, to be fair its near enough pointless for the road.

 

there is far less drama than i though, at 250bhp it puts all the power down with no issues once on boost its unbelievable and quite violent as you will see in the vid clips below.

 

took the mrs out to the pub in the week, gave it a cheeky 0-insert number here test first time ive lauched it with turbo power, looking forward to getting more used it it!

Was she happy with her whiplash

Was she happy with her whiplash

not really she was sick, and not really that happy i did buy her a curry though in my defence 

[Bumblebee]

It certainly looks like fun

[RalphyBMW]

335 BHP! What is the BHP/ton?

[Thealastair34]

335 BHP! What is the BHP/ton?

About 610

[Thealastair34]

had a engine issue turns out a damaged piston ring. 

 

so all the engine has been stripped and inspected everything is all within tolerance which is good news getting a fresh lick of paint and going back together

 

while i had the head off i had larger exhaust valves with 3 angle valve seats cut with a little more headwork to reduce turbo lag and increase the power.
