Geez, time flies when you're busier than a 1 legged tap dancer... 634 day since last post.. phew.
Anyway, Steve brought back his really nice twin throttle 355 running a LS1 ecu on it, which btw, isn't a real good suitable setup, in the present manner, how it is setup to run off a VT distributor with just 1 coil...
Anyway he has been having heaps of trouble and has been running a Bosch 044, another part I don't rate or like... he thought it might be the lift fuel pump, so replaced it with a Walbro 255L intake pump, and this didn't fix the problems either.
So after various eliminating test today, we bypassed the 044 and hey presto, it fixed it...
As you can see, we have now eliminated the whole swirl pot crap dinosaur setup.
I'm always advising guys against this method of 2 pumps and swirlpot, and here is yet another example, and for the unwary of how you can blow your engine or minimum of head gaskets when one pump sh*ts itself...

Adam brought his stock manual LS1 Cobra in that I did the harness and start tune for, and it wasn't running too happy ... I soon spotted that the o2 sensor plugs were arse about... which really upsets things..
Anyway it smashed out 348rwhp which is a bit of a record for a stocky... and with that power to weight ratio, its like driving a 500hp Commodore...

Next up is Jacksons LS1 turbo ute, which I tuned a while back but developed a misfire.... ummm the turbo melted the left bank leads.... anyway all fixed and better insulated, with 525rwhp on 8.5lb boost...
