what bhp could i get ?

[Teddy]

i have just rebuilt my 60 000 mile xud engine its running a tdo4L turbo with 11mm pump with gov mod and ground ida pin with front mount just wondered what the best psi to run the tdo4 on and what bhp ruffly can i get

[Piggy]

some, if not most, weld the wastegate shut on the td04...thus achieveing often close to 30psi...but theres not much gain above 25psi from what I have seen of RR charts...

170bhp should be easily attainable I would think...but unless you have HDi rods, you may be dramatically reducing the engine life pushing harder than that

[Teddy]

heard mix views off welding the waste gate ruining manual boost controler atm will see what it does ad heard a lot of stories of con rods popping threw the block

[Jimbo]

I dont think its case of ' if ' more like when it throws a rod. Especially if you weld the wg. Keep a wastegate and dont push it to hard should be ok with hdi rods

[Piggy]

Yeah I would prefer MBC

high psi normally means big bang from turbo, XUDs can throw rods at low boost from standard setups....but no point being on the limit of going bang all the time!

[Teddy]

hopefully doesnt go bang before fcs haha engine has only done 60 000 miles and been well looked after as owned it since it 40 000 and only had 1 past owner so hopefully last a bit

Padge used to run something like 40psi, he said it was great. Mines peaks at 28psi on the top mount and it goes well lol

[Teddy]

yer know padge got him on facebook properly try about 25psi to start and see what happens

[Tom]

If your running a front mount i would imagine up near 30 would be pretty tasteful. Mines pretty hellish when you really get tanking along!

[Teddy]

u had yours on rollers tom

[Tom]

No mate costs to much lol, 50quid for a couple runs down here, like f*ck rather just put 50 quid of fuel in and have a week of hooning!

[strictly_perv]

You should see good power from the 11mm. I went to a dyno yesterday and saw a car just like mine, XUD K04 turbo FMIC 11mm and that made 190bhp

[Teddy]

wow that did i will be happy around 170 bhp will do me fine

[Dave]

Welding the wastegate totally depends on the hotside of the turbo. If you have a small hotside, keep the wastegate! Stick to about 25psi, and it'll be fine, dont run too much advance either!

[Teddy]

well dropped engine in today so hopefully can give it a go tommorow
