looking good dan! last time we spoke to had an issue with the lower ball joint and the brakes, you managed to get that sorted? And will you be making an apperance with this at the malta on sunday??

carmadbaker · 20-03-12, 07:16 AM

yeah JUST sorted all that mate

and the smoking! woop woop! had to pop some 10mm spacers behind the disks to bring it away from the lower arm, worked out good though

Im attempting to sort MOT and tax this week, if i manage then yes... if not... i'll bring the Lotus lol

Good good! i should hopefully be there, i have work at 1:00, but its only round the corner so should be able to stop for a quick chat

awesome spec but imo you deffo need to ditch the 2.5 inch system for a 3 inch.

carmadbaker · 20-03-12, 04:08 PM

Did contemplate it, the cost was alot more which sort of put me off. The guy who built it was all setup and ready to build me a 3" system but told me unless i was aiming for more than 500bhp it wouldn't be that advantagous (it genuinally is totally straight through lol)

well i cant comment on the t series as ive never had any experience of it , but i know for vauxhall and vag that anything approaching 300 bhp and you start to gain from a full 3 inch, on a astra vxr pushing 290 on a 2.5 system it will make 300 on a 3 inch system.
When i had my zs with audi engine it was making more power than any of the seat cupra guys with the same mods, only difference was full 3 inch turbo back zorst. Ive just had a full turbo back 3 inch on mine to replace full 2.5 system , its on rollers sat morning, ill let you know the difference but i can tell you now just from the butt dyno that its got more top end power.
At 400 or 450 bhp a 2.5 inch system will deffinitely be holding your power back imo.

This sounds interesting......
On my T16 maestro I do not have PAS (prefer it that way, you only need it in car parks and it ain't a going to the shops car

) and have managed to kill 2 water pumps as I'm not running PAS fluid through the combined pumps.

I have been considering a Craig Davis set up, what are you using?

How have you dealt with removing the water pump?

My other problem is I had a high capacity rad built and TBH if anything it is too large but because of the capacity I don't have problems having the turbo cooled through the standard arrangment, besides I'm currently running standard power so it never gets that hot.

proof will be in the pudding

lol supporting mods and turbo type play a huge roll in exhaust selection. hopefully i got it right

I do indeed use the davis craig water pump and controller, its a very nice bit of kit i must admit! the water pump impeller i removed and built a small diverter dam inside to help direct water flow, the pump seals still do get a constant flow of water to keep them "lubricated" so to speak! seems to work very well, keeps my engine at 95degrees easily

update as promised.
my car made well under the expected power at just 246 bhp and similar torque, but the boost gauge showed boost was very low, nowhere near what it should have been.
Today i took it have it checked out, then have it custom remapped and re rollered.
It made 306 bhp and 330ftlb.
285-290 is the expected number with a 2.5 inch turbo back exhaust, the tech guy said it wouldnt have made the power without the 3 inch downpipe.
