Bloody hell that is awsome , had the stereo up loud for that

Those 35's make a shit load of noise though! The flat spots gone. Still needs an on road tune with the laptop, but it's going better than it has been. Only around 200kW at the wheels. So it's far from tuned how I would like it.
It'll do for the fun day tomorrow. :bounce:

Sounds awesome Looking forward to seeing it in action tomorrow

Yes it doen't, but all in and all, I thought we all had a great day today!

The FJ40 is booked in for another dyno run next week. I'll be using 33's this time. An a mobile laptop tune the week after. Just have to sort some fuel pump issues first. Will post some video of it. Should sound sweeter than the last run. Should get some more horse power to. YEAH!!

you will get a much better dyno result using smaller wheels do a power run with the smaller wheels before you do the tuning or you wont have a start point to compare to

I agree. I'm interested to see the results. The fuel issues will be sorted with a bigger breather vent to the petrol tank. As well as a another smaller fuel cell off the main fuel tank keeping the fuel pressure consistent. I've had problems with the fuel pressure dropping when I'm at maximum g forces.

have you had another dyno run yet pete!!interested to see how much more power they can get out of a ls1 by tuning ,what computer do you run

I did have the 40 booked in for a dyno run. But then thought I'd get the mods done on it first. So the Holden had a dyno run instead. After getting the stainless 3 inch twin exhaust system installed, it needed another tune up anyway. That went really well!! Only roller rockers to go on the Holden's LS1 to get it where I want it. I've only got 255kW's at the rear wheels at the moment. That's not to shappy though.
What computer do I use on the 40's LS1? The stock GM computer. (it's bolted down in the glove box) Any other wouldn't perform as well. That's what "Kevin Geary" tells me. And he's been working on those motors for years. He's been helping me get the most out of my V8's from the time I first brought them. Before going out on his own, he was the HSV specialist for Blackwells for 12 years. He knows his stuff.
