I dont think any of the bosch pumps are a straight fit, you have to modify the brackets that it sits on to get it to "bolt" into place. I have a bosch 910 in mine, went into the tank and there was a thread for a "DIY" bosch 040 or 044 into the tank of a gtst, again you have to modify the brackets but I believe it did fit in.

I think I'll be going. Was supposed to be playing cricket, but seems its my turn to sit out.

I'll be running mine soon.

The reason I get shit fuel consumption at the moment, is that I'm running a big turbo and I just got it back from being tuned, so I'm driving it rather hard

Doesnt appear so, I also have the bosch 910 pump. The DD dyno at SST reads low, we could go to another dyno if you want and it'd probably show 450hp or slightly more. There are a few large hearted dyno's here in Perth.

Slightly. At the moment I'm lucky to get 300km's to a tank... damn heavy right foot Its funny, I put my foot down and I can watch the fuel tank gauge going down

I'm making 339hp @ wheels (on 1bar) currently, but at the flow limits of the stock exhaust manifold, as we had to pull a reasonable amount of timing out of the top end to stop it from pinging. I also think its getting fairly hot in there now too, so I need to wrap my dump pipe and get a ceramic coated exhaust manifold to help keep it a bit cooler. I know I am definately running stock injectors I had them ripped out, cleaned and tested for flow. All were flowing well and had excellent spray patterns and I'm also at only just touching 70% duty cycle on them. It will be good when I finally replaced the stock manifold and find out what the turbo is capable of with perhaps 1.2bar on the dial, just to try it out and then do the pistons to make sure its going to hold together Nice figure paul... *sigh* I dont think I'll ever catch you.

It'll be a long time before I beat you, if at all ever Spent too much cash already Still happy with the car, it'll lay down a low 12 I'm hoping.

Heh, your a bit keen hicks... the car isnt finished yet and you've updated your sig whats left to do?

Hello. Yeah the peak power reading was a bit disappointing, but the midrange of the car is huge. Comes on boost quicker and has plenty of torque to wack you back into the seat. Going to need a new manifold sometime as the stock one is shite and falling apart on me, plus with the better flow I think the car will make a bit more power, probably closer to 350-360hp peak with more timing in the top end.

*yawn*

mmmm... pistons

Evening

I love my td06-20g now I have a fully tuned ecu... its the ducks nuts silky smooth power delivery with full boost coming on at 4300rpm on the stock shity exhaust manifold Just need a tubular or tuned length manifold and maybe an exhaust cam gear

I agree and disagree with some of this sydneykid. I'm making 253kw @ rear wheels. I had my stock injectors taken out, cleaned and then tested for flow to make sure they were up to the task and then put back in. With a bosch 910 fuel pump upping the pressure the stock injectors are only at 70% of their flow (another car is making 274kw @ wheels with the same injectors, pump and a fuel reg and it seems it still has a bit of headroom left). I cant make anymore power until I change the exhaust manifold as that is holding up my flow badly now so I agree with that point.

I'm making about 250kw @ wheels on a td06-20g with a 16cm exhaust housing. With a good exhaust manifold and ecu it should spool up by 4000rpm (currently spooled by 4300rpm on the stock exhaust manifold) and people say that with an adjustable exhaust cam gear it should spool up by 3500rpm. Power delivery is silky smooth, do a search for "trust td06 stage" and you'll find a copy of my before and after dyno curves (before ecu and after), the difference a good fully tunable computer makes is huge. However to get closer to 300kw @ wheels, I'm gonna need a new exhaust manifold (will be done eventually now cos the stock one is going to break one day) and some good pistons so I can crank the boost up to 17-18psi, even then I think I'll max out around 280-290kw dont think I'll quite hit 300kw.

Bad cops bad cops... whatya gonna do

afternoon whores

Look at the boost graph and see where the power dips and then spikes unbelievably at the top end (that is the run just after the turbo got put on), we think the stock ecu was pulling a heap of timing out in the midrange where it dipped badly and then stuffing a shitload in to make it spike like that, I was also running the stock fuel pump (got changed a few days after) and it was very lean at that point I cant remember exactly but it was somewhere in the high 12's to 13 afr... very dangerous After putting in the bosch 910 pump the afr's got rich again and power dropped to 322hp on 12psi, now its tuned with 15psi making 339hp. As i said it would seem the exhaust manifold is holding up my flow and it will be replaced when the starts to leak, with the better flow maybe we can make another 15-20hp

nope, map sensor.

Boost graph

About 8 weeks ago I posted up some dyno sheets of my car with a td06h-20g (16cm^2 exhaust housing). It made 344hp @ wheels with a very ugly power curve due to still running the stock computer. Well its been in again and come out with a wolf3d ecu. Peak power is down, infact we had to run slightly more boost to achieve the same power level (albiet 4.5hp down). What you can see from the before and after graphs is a huge increase in midrange torque and hp (80hp at one point on the curve). The turbo comes on quicker and the power delivery is silky smooth. I am a bit disappointed that the car didnt make 370hp, I thought it would do it easily, but the car is so much better and faster to drive now. It looks like I'll be changing the exhaust manifold definately now, not sure when just a matter of time, as two bolts have been spat out already and it will sag and start to leak at some stage. Hopefully with the better flow of a tubular or tuned length manifold we can sneak more ignition timing into the top end (we had to pull a fair bit out to stop it pinging) to make up some lost HP. I'm also thinking about a cam gear at some stage too. About the only thing left to do would be upgrade the internals, but thats a long long time off if ever, I've already spent bigtime (may not be bigtime to some people ) on the bolt on engine bits.

Steve's started doing the basics on the ecu now. I'll be down there later on this arvo... see you then... off to look at baby furniture
