Hehe, nice work Pete. You can imagine how my missus feels when she's behind the wheel of my ute,  .
I dont think the 70mm T/B would have made that much difference but it certainly would have helped. Yep definately get it on the dyno. Im guessing 230-240rwhp at around 5300rpm.

Everyone is guessing 30 or 40 more HP than me. I'm not expecting much as I don't want to be disappointed.
Only time I put a car on the dyno was my bog stock EL Fairmont Ghia V8 and it pulled a massive 128rwhp. So I'm scared of the figures so I guess low. If I got 230rwhp I would be jumping for joy. |

I think you'll find that must have been 128rwkw not hp, 128rwhp is rediculous lol. Well i hope it was rwkw anyway

The only thing I beat was a worn out EA 6 cylinder auto. Nah Scaffy I haven't booked it in yet. I'll try and get it done after work this week if we get a slightly warmer day. I'm hoping for above 20 degrees so the air temp correction won't throw out the reading too much <----See I learn a lot from you guys.

Well, just for the record, my guesstimation is 220-230rwhp. Timmeh already knew that though

I hope MCE are open Saturday mornings cause the Great (s**t) Northern Highway is under renovations again and I have to use it to get to work and my car will get stone chipped to the max so it'll have to be a weekend dyno run.
I'll be running the XR6 during the week. |

Yeah, I think they've just started opening on Saturday mornings quite recently.

Righto folks this is it.
The car is running lean as anything. Good thing I never thrash the car or rev it past 3 grand. 204 rwhp which is what I was guessing. Because it was so lean the MCE didn't want to run it again for fear of blowing my car up. He fidled with it and the MAF is working fine cause he was blocking it off with his hand and the AF went down. Then he got some tape and blocked off about 80% of my K&N filter with it to reduce the amount of air getting in. Then with a cringe he ran her again on the dyno. We got 240rwhp but still lean. It wasn't printed out as he said it would be an inconsistent result so the 204 is what was printed. Basically we all know it can't run like that so I'm getting a tune done next Friday to sort it out. I'll be getting the GT MAF on and the 24Lb injectors fitted and then switch chip eliminator tuned. Rather pay the $1500 tuning now than the $6 grand new engine later. Can't afford it but it has to be done.

Wow that is a bit lean isn't it...
Look forward to seeing the results after a new MAF, injectors and tune. I'm guessing the current fuel consumption isn't too bad

About 550ks - 600ks occasionally 650ks per tank.
Good thing I only run Ultimate 98 cause if I ran regular 91 I don't think my engine would be alive right now. |

Jeez Pete, thats pretty bad!!
A fuel pressure guage and an adjustable reg would have been pretty handy in that situation just as something else that could have been checked/modified. Haha, no wonder the fuel economy has been great. I think there is an issue elsewhere that wasnt allowing the ELGT ECU to work properly. You'll be better off with the new tune anyway. Look forward to seeing how it all turns out. Jeff

Its going to cost me $1500 all up to get the custom tune and injectors sorted.
The guy at MCE reckons I should get about 260rwhp with the tune on board. For now I have to run it with 80% of the air filter blocked to reduce the air getting in. The other option is putting the stock TB on to also reduce it. But I'll drive with a light foot instead. So for the next week I'll have 150rwkw that I can't use. Next Friday night if not Saturday I'll post up the new dyno sheet with hopefully the figures we want. Also for the hell of it I'll get my car weighed with a full tank and no driver. |
