No not blue alloys if i recall correctly they were just silver ones :)

Driving on king richards road with a shopping list on the door. Anyone from here?

For comparison: I have tried NOS intercooler sprays and using 100HP jets spraying on the IC you get around 30HP increase. Personally I'd rather inject that NOS into the engine and make better use of it. Water is of course very cheap so anything that helps the intercooler heat transfer efficiency must be good. So long as the thing driving it doesn't consume more power than you gain. Regards Pete

Guys I can get you genuine Philips Ballast HID conversion kits Full UK support, spares and repairs. Converts back to ordinary bulbs in seconds. (easily transportable to your next car) 6000K HID's for £370 + VAT 4200K HID's for £308 + VAT If you buy 5 or more I can drop this to £350+VAT (6000K) and £290+VAT (4200K) Take a look at my home page for a view of the 6000K kit I installed about 3 years ago now. (and not ONE problem with the kit since fitting) My Supra HID Kit I can also offer main beams in Philips Blue Vision (matches the 4200K HID kit perfectly) at £10 each plus £2 for each side lamp. So package deal.... 4200K HID kit plus Blue Vision Main beam plus side lamps all for £320+VAT 6000K HID kit plus Blue Vision Main beam plus side lamps all for £380+VAT email me on peter@thor-racing.co.uk or telephone 01676 535888 You can have them in 2 days! To save postage you can collect at any dyno day or at the many events throughout the summer. Or get them fitted by us for £45 all in. Regards Pete ps. Tell me where to send the cheque for the TRADER subscription :)

Yep. That was muy Dad :) Helped out for the day doing admin. I've seen the booking. Yes pretty much. The car is settled down at 2000rpm before the runs starts and at part throttle. Once the power run begins I increase the throttle quickly. The rate of increase in the boost pressure graph shows the rate of spool up. Now the run was set for 12s, from 2000rpm to 6500rpm (No point going into the redline as you're past peak power and torque) So you can estimate the time of spool up from that. It's a little tricky as you try to set up each make of car to perform a power run over as short a space of time as possible (to reduce excessive stress) but it cannot be too quick as the engine must be allowed to generate it's maximum torque at each RPM. Between 12-15s is normally O.K. I'd say put a 700ft/lb torque drag car on for 8s. I would also recommend you all fit an exhaust downpipe boss. So that the wideband O2 sensor can be mounted about 1m from the exhaust manifold in the downpipe. It means we get a faster response to the O2 changes and hence more time to get off the throttle before things go pop. There is a bolt that fits into it to act as a bung. These are £15+VAT, machined stainless steel. Regards Pete

Yes, the weight of the wheels and thus the torque required to spin them will reduce the actual at the "road interface" figure. I do not have a formula for this. Maybe a budding scientist will work this out. BUT the "road interface" figure is very dependant on tyre pressures, the amount of strapping down the car gets i.e. the force on the tire pushing down) and thus the grip on the rollers. So although the figures are slightly higher I believe them to be more REPEATABLE, time and time again! (although I will also say more accurate due to the 0% loss of traction, as there is nothing to slip. However I'm not stupid enough to argue this point with the hundreds of traditional rollers around.) The differences on the graphs are always due to something, like temperature, fuel or ignition. Never wheel slip. Anyway I hope when some of you come back I can demonstrate a real increase in power, before and after plots. Regards Pete

I'll sort something out with AJay about discounts and trader status etc. I'm sure we can sort something out. Cheers Pete

Many thanks to all who attended. Don't think the farmer was too impressed with the numbers of cars (I was :) ) Appologies to the members I was a little short with about directions :x: I will address this next time with some grass verge signs. I was just so busy getting wheels off to correctly explain where you needed to go on the telephone. Plus I'm not too sure of the area myself (having just moved in) If you need any advice on what your Dyno printout means and what can be done to fix it then please ask. I was getting worried for the Z's at first as a lot were detting but this was an isolated few. But goes to show that you could be damaging your engines over time if you don't address the worryingly lean fueling on some of them. I hope some of you might be interested in future tuning work and would look to THOR for some assistance. I'm going to become a trader on this forum a.s.a.p. Best regards Pete
