BRD st185 hoping for 400bhp now mapped at 397bhp 370ft/lbs

mixer72 · Apr 28, 2010

right after a lot of delays and a very long drive down to Surry to get the car mapped we now have some good news and some bad news, the good news is that the car is running great and my god is it quick, the bad news is that we only managed to get 377.4bhp

bhp at the fly wheel

bhp at wheels

A/F + boost

Greg did say they there is plenty left in the engine juts the turbo was starting to blow hot air so not worth pushing it anymore, and he also said that he felt that set up on the rollers were not the most accurate may not the right thing to say more that the set up is different to what my car is use to being maped on and it would be worth me going to Weston and doing a power run as this is where the car has bin mapped before. but I do have to say it pulls much harder and feels a so much quick that what it did before, all in all im happy with how it drives

quick update, gave the car a dam good the thrashing at the funweekend

and i managed to get 12.44 1/4mile well happy with that as my launch were pants lol

Good shit.

Love your car man.

Ever gonna clock that turbo?

mixer72 · May 2, 2010

might clock the turbo will see how things go but i and i have just noticed that im not runing 1.6bar if you look at my power graph im just hiting 1.5 then it tailes off to 1.4bar witch i now no it down to my boost contorle as it can only handle upto 1.2bar max so need would explane the 23is bhp down from the 400bhp i was hoping for, time for a new controler i think

new 52mm 2core ally rad fitted

that sould help keep things cool

mixer72 · Jul 27, 2010

bit of an update as some of my know i have bin getting over heating problem and it looks like it is the head lifting under boost, and the other thing i have now got is oil vapour smoke out the air filter

and to add to that my oil pressure seem to be very low :?

But now we have some good new I have just checked the oil pressure with a Snap-on oil pressure gauge and all is well, at idle I’m getting 20psi and as soon as I rev the engine it goes up to 50psi so it is just my gauge or sender to the gauge
just been out for a spin with both the cam breather and idle valve pipe disconnected and I’m still getting oil vapour smoke out the air filter so I’m guessing it can only be the turbo seal on the cold side

so its turbo off and send it back to TT and see if that will fix it under warranty as I have only had it 6months and done 600miles on it. retorqued the head so fingers crossed that will sort the head lift and my over heating.

mixer72 · Jul 27, 2010

update on the turbo smoking, i took the turbo off to day and you can see all the oil that the seal is letting out

mixer72 · Jul 27, 2010

good new

the new turbo is now fitted and runing

it looks to me as if that have sent me a new turbo with my 1.4bar actuator fitted to it, not bin of a blast yet only a steady drive to make shore every thing is ok

i did have to pay half to the repair bill so not to bad i gess

a bit of an update on the engine, as i was still getting over heating problems we did a hydrocarbon test and it showed that the head was leaking

so we got the head off and First indications show no obvious gasket problems but it appears it may of leaked some oil towards the no.3 cylinder area and gravitating on the passenger side. This verifies the oil puddle in the workshop being on that side.

Also, there appears some bluish tinting near some of the waterways, indicating super heating.
Plus...the cylinders show wear on the thrust sides, are smooth and blacked, due to very rich mixtures.
The cross-hatching has faded and you will burn more oil. Honing is the answer, but requires piston removal etc.
We then had a look at the head and it has warped near no.2 and no.3 cylinder so the head is now off the be skimmed,

here are a few photos of the block

Pistons and bearings out today.

Have collected the head also and I'll do a leak test tomorrow.

The pistons are fine but the rod bearings have worn and are rather scored

ok little update on the car, i have now fitted some nice new 12" fans

mixer72 · Dec 22, 2011

been a long time so here is a bit of an update

got some more bits today to go in the car and nice Fire Eater

I have now bolted it all in and then started to add some more roll bars to it
first get some roll cage tube

then weld the bolt in eyes

then weld the eye hook to the cage

I all so fitted a cross brace to the roll bar

need to make shore everything lines up

did the same to the rear

and you end up with this

I them painted it all up

I then made some triangulated braces to brace the roll over bar to the body of the car and fitted it to the old seat belts mounting points

after making shore it all lines up ok I them welded it all in palace

mixer72 · Dec 22, 2011

adding these rely stiffened everything up

after all of this you end up with a nice strong roll cage

relocated the batter to the middle of the car and started to fit the fire extinguisher today

here you can see the nozzle in the drivers foot well

and here you can see the 1 on the passenger foot well plus the hand held

will finish the rest of the install when i have dont then engine strip down and rings replace

mixer72 · Dec 22, 2011

few more bits done today finished the turbo clocking bracket

this is my 1.4bar actuator

all fitted ready to go

finished the new cold side of the intercooler pipe work

hade to make some new pipes up using my little tool

so now i have her to this stage

all i have goto do now if sort out the hot side witch is now going to be easy as there isent much room witcha 52mm rad in the weay

on a good not i managed to fix the plug
solderd in and fix 2 new wiers to the pulg

then sealed it all up job done

should have new crank pully mid week so hopeing to fire it all up the weekend

mixer72 · Dec 22, 2011

just go to paint inside the air box, but after Rich left we got it all fired up first time and all sounds good

so very happy, just need to get it booked in for mapping now and running in.
a few more finishing of bits

I have made a new and improved rear strut brace

I had some 5mm thick plates made up

but found that the holes were in the wrong place

so after a bit or re drilling got the plates to fit

got some of the roll cage tube I have and made the brace up

then did a bit of welding

and you end up with this

as you can see much thicker and stronger then the stock 1 you can get

just got fill the old holes up and paint it up

mixer72 · Dec 22, 2011

just fitted the new rear strut brace

old and new

ok just got back in from having the car mapped and im very happy

at the flywheel

a go faster mod lol

mixer72 · Dec 22, 2011

here is a pic of the car all straped in th trailer ready to go for a track day

mixer72 · Dec 22, 2011

here is what the old mirror looks like on the car

and my god do they way a tone

and here is the new light weight set on the car, only trial fitted for now to see how they look,

they need a little bit of moding but happy with how they look so far and so much lighter

and the best bit is they only cost me £9

mixer72 · Dec 22, 2011

got some bad new

after the track day i was out testing the car and the crank thrust bearings failed

so I striped the sump of to have a look and what I found was not good

all of this was in the sump

I then took of the crank bearing to see what the thrust bearings look like and found this

as you can see it has worn away the edge of the bearing cap and killed the bearing and thrust bearings.

I then had a look at the big end bearings things are not good

number 2 and 4 big end bearing have gone and the crank is nakerd,

and I can all so see where bits of metal have gone up and hit number 3 piston

so it looks like it going to have to be a full strip down to see if the boars rare ok or if they need honing or even a reboar
