Yep.. I can imagine my local guy's face when i tell him to keep loosening the straps until I see the 'Tension Release boost mod' :-D

I was looking through the ls1.com.au forums the other day (from a link on here) - They were talking about Dyno'ing, and the fact that they got different results from how tightly the car was strapped down. Is there a specific tightness etc? - I'd guess you need to strap her down to get traction, but can you tighten too much? IIRC, they lost power from stapping down a car too much!!!!? (I could see if they didn't strap it down enough, but....) I'd link to the post, but the forums on ls1 doesn't have a search function I can find... It was a post talking about test results from supercharging/turbocharging a V8 engine. Thoughts? To Quote from the LS1's Forums : We have done back-to-back testing between our dyno and 3 others (CSV, Autotechnique, G & D) and found there to be excellent consistancy between all 4 dyno's +/- 5rwkw @ ~300rwkw. All done on the same day, same tune. We run ours in DIN certification, which just happens to reduce the observed numbers by about the same as the traction-slip encountered. We participated in some testing by the author of the DynoLogic software (Andrew E) to try and establish what is "lost" through tyres and roller inertia and it was VERY interesting. As a "rule of thumb" we found that 10 to 25rwkw could be sacrificed by varying tyre pressures and vehicle retention (strapping down). This was again verified recently at the F1 Performance dyno day when our Monaro was run ... the 1st run was 317rwkw and showing a bit of wheelspin, so I asked it to be pulled down tighter ... the next 2 runs were about 300rwkw. My fault, but it indicates the method of strapping can have a significant effect. http://www.ls1.com.au/forum/showthread.php...89&page=2&pp=15

Well, since I had the 100K done, it seems that this problem has started... I'm not sure if it's related to that tbh.

race, BP's been doing it here (Bathurst) for at least the last 4 months then..... :-/ or 98 isn't 98 here.... Had the same effect on the syd coast when was forced to use '96' - damn close

Ok, I'm running a SII R33 GTST, with the following : Mines ECU (afaik jap tuned) FMIC, T3/4 Hibrid, Steel, BB, Rising Rate Reg, Dump Pipes, 3" cat back, Pod (no heat sheild, as changing to box) Last Dyno, 197rwkw. For a good while, i have been thinking that the fuel pump was on its way out, as it couldn't cope (aka keep fuel flowing) on a 2nd/3rd gear hard boost (10psi) - before the last cruise, on BP fuel, added some octane booster as well - still pinged, hard. It was pinging like it was going out of fashion - usually at about 5-6k, 10 pis, 80-90% throttle) (If kept at 3/4 throttle most of the way, and then pushed, no pinging - seemed like pressure/fuel delivery) Yesterday, I filled up at shell, instead of BP, and no pinging... Is there any difference between BP & Shell 98? help... Time to get a new pump, stick with shell? - any other ideas?

Drop into the computer shop i'm working in....... The boss decided to create Bathurst via skaletrix.... if you need directions (if in bathurst) - 6332 6829

Is anyone visiting bathurst for the race? If so, it'd be nice to get together etc, sometime over the weekend.... post if you are, and i'll try and sort something out, even if it's beer etc....
