Alright folks

just thought I would post up how i got on the other day through at Andy's

best figure was 432bhp 407 lbs-ft torque from the T+ running 30% E85 and 3ml per L of fuel and the car pulls like a train. 1 bar of boost by 3100 rpm and 1.6 - 1.65 bar by 3300 rpm which is pretty dam good for a MD321T+ but Andy did say that my car can do strange things with turbos and makes them perform better than they should B)

We had an air leak somewhere and couldnt find it so Andy had to be a bit more creative to get the fueling right, got home and checked the intercooler (easiest place to start) by giving it a clean out as there was some oil in it anyway and to my amazement the petrol started leaking out the seams...lol. Andy told me not to fix it if i found it as I would end up running lean and probably melt something...oh well. At least the intercooler is an easy fix as its just needing the crimps cripmed back down and all should be fine.

Andy was saying the main limiting factors now are my ECU, and lack of boost controler as he cant give me any more boost on the stock ECU as it only reads up to 1.75 bar and he needs to leave a wee bit in reserve so the ECU can detect any boost spikes. He was saying that if he mapped the car right up to the 1.75 bar and if I were to get a boost surge the ECU would not see it and I would blow myself up so on that note im glad he only mapped it to 1.6 - 1.65 bar. If I had a boost controller and 3 port boost solenoid he could have given me a bit more boost.

During the mapping session Andy was finding it hard to control the boost and at one point i even saw my boost gauge do a full 360!!!! lol. on a posative note, when the car did over boost a tad to somewhere well over 2 bar Andy didnt hear any det what so ever. We ended up going back to his place to change the restrictor as he thought the one that was fitted was too restrictive which proved to be correct and all was well.

On the way home during some spirited gear changine 3rd-4th up to 6500 rpm and reasonably into 5th the check engine light came on but after a while of normal driving went back out.

Later that night I wanted to try my launch control with the new turbo (Settings wernt changed and still pings off about 5300 rpm) brought the car onto the launch control, built up the revs, poped the clutch and nothin, the car almost died and i think ive knackered something.as the check engine light came on so I went home and parked it up.

Yesterday i went back out to the car as i had to deliver some crimbo pressies to my wee god daughter and all seemed well with the car, all the hoses looked fine under the bonnet and the CEL was off again so naturally I drove slow at the start till the car was nice and warm then gradually started giving it some beans, the car felt great again. On the way home I decided to use the full rev range in a couple of gears and when I booted it in 3rd and 4th the boost tails off to about 1.2 bar over about 4500 - 5000 rpm which I didnt remember it doing before.

Will send Andy an e-mail but im just going to bide my time and save up for Solaris as it does not require the AVCR and has the full knock control and full wideband functionality along with being a dam good ECU package and a good front mount and Andy told me I should be good for the high 400's or possibly more if im lucky.

I did rush into these mods a bit as I was planning on waiting untill mext year untill I could afford the ECU, front mount and another couple of bits and bobs but once the Turbo and Injectors arrived a sort of red mist decended and i just had to have them fitted RIGHT AWAY :) Im glad I did as it has highlighted a few issues but the car is still running strong and safe

next round should be the middle of next year :D :D :D in time for the August Knockhill

A still happy

Graeme

Oh yea forgot about the fuel pump, its still working fine, I thought Greers had fitted a 255 lph Bosch pump a few years ago but Andy was saying that it was still flowing fine and he didnt need to dial in any extra injector duty cycle at the top end, injectors running at 73% on the 800's but did recomend doubling up the pump for next time for added safety

I also forgot to say a big thankyou to Jimzer for giving me a hand fitting my fuel pressure regulator, cheers jim B)

Sounds like some fun you've had there G.

Your car will be impressive when it gets the new ecu etc. Have you upgraded any of the internals? How much can the newage internals handle anyway?

Nope, not touched the internals.

I think the newages should be good for around the 500bhp mark as long as fueling and other supporting mods are spot on like oil cooler etc

if money allows the next round should see

Solaris

oil cooler

2nd fuel pump, and probably a swirl pot as i used to get fuel surge at half a tank round the hairpin at knockhill.

front mount, possibly with rotated manifold depending on which kit i go for and again depending on how much cash I have spare

And toying with Aquamist as Jim has had some nice results with his, also for a bit of added safety

We shall see, not going to think about it too much untill after the car is payed off in Feb

Nice one mate, I even understood a lot of it, ha! Amazing thing is, the more money you spend the more money you have to spend :) I have already out-modded stuff. So, if I add a bigger turbo, I'm looking at a gearbox and clutch on top of the price of the turbo, plus an oil cooler and most likely injectors, pffff puts me out of the running for a while!

Hope you get all your niggles sorted and have your car in tip-top running order B) The only thing you never mentioned was a 2.5 upgrade... tempted?

Graeme,

1.6 bar by 3300 is well good, how could you tell without an avcr?

my 20g hits 1.55 by 3400 in 5th gear

when are you getting the shove into the seat?

iam considering the 321T next year so really keen to see your results

All this... i get a bar of boost @ and full boost @ is a crock of $hit, it's when you

get the shove in the back, that's a more realistic full boost. Sorry, rant over. :D

It's good to hear you are happy with your car Graham, onwards and upwards old boy.

He got left eye on Defi boost gauge and right eye on rev counter and his middle eye on the road!

Thats how

Decent results... and a fair bit of scope for improvement once the next round of mods are served up. :D

What clutch are you running and how old is it??

Cheers,

Grant

graeme's using a twin plate now grant so no worries there.

dont think the car is running as much power as it should be for that turbo/fuel but will still give some of the bigger power cars a run for their money on the road :D

Hello there Grant

Im running an exedy twin plate Hyper compe D clutch so should be strong enough for what im going to throw at it, been in the car for a month

Neil - The intercooler is leaking as when I went to clean the oil residue out it petrol came piddling out of the top right hand corner. Andy told me it is possible to re crimp the edges back down so I will give that a try when I get home and go for a map tweek so i wont be running lean.

All other mods ar on hold at the moment as I have to pay the final payment for the car in Feb £7300 !! :thumbup: (would be lucky to get much more than that if I were to sell the car in the current climate ffs)

All in the fullness of time ;)

Graeme, decent bit of kit that.... I'm sure it'll put the power down without any hassle. Be interesting to see what sort of improvement you can put in up the 1/4 mile with your new found oomph. :thumbup:

LOL Pedro

You dont need to be a man to do the 1/4 mile, the real test of manhood is going round corners way too fast enough :thumbup:

not planning on doing much of the 1/4 mile as i have already broken 2 clutches and I far prefer going round corners on the limit of traction ;)
