In the continuing effort to maintain parity in the NHRA Pro Mod Drag Racing Series presented by ProCare Rx, the NHRA Technical Department is increasing the minimum weight for turbocharged entries from 2,650 pounds to 2,700 pounds. The minimum weight for nitrous assisted entries will remain at 2,425 pounds while the minimum weight for supercharged entries will remain at 2,650 pounds. Turbocharged entries will also have a reduction in maximum allowable engine size from 540 cubic inches to 526 cubic inches. Additionally, in an effort to maintain parity and reduce development costs of turbocharged entries, a spec 88 mm turbocharger will be mandated. This turbocharger will be manufactured only by Precision Turbo & Engine. The turbine housing part number will be 10301-XXX and the compressor wheel will be A24288C. Only this approved turbocharger and it components will be permitted. Any modification to the spec turbocharger is prohibited. These rule changes will go into effect January 1, 2012. Additional parity adjustments will be made as necessary.

Graham,

I think he uses any excuse to mention the fact he watched the racing in America. That makes us unknowledgeable to him.

He even questioned people's ability to tune a car over here...

cause no turbo cars contested the championship in europe is a good start.....
and the only two turbo pro mod cars so far in europe that have started to show promise were both in their First year of development one ended up holding the european pro mod speed record and one the fastest ever british pro mod...
WIth a lot more turbo pro mods in europe next year im sure we will see them start to threated within the next two years

and in the US if they had started the season as strongly as they finished they probably would have, the turbo cars have so much more horsepower and torque that its not so easy to control but when its figured out as it is starting to be....wait and see

any more experts wanna have a dig???

I am no expert, and I have never been to America (I realise now those two are connected...).

I suggest the only reason a turbo car didn't win the GSA series in the states was musical chairs at R2B2...

exactly.....right on both counts
r2b2 lost the championship that was theirs to win

and if you havent watched racing in the states you may as well hide under a stone with the rest of the pond life..... or so it would seem hahaha
vomit

I agree, the Performance is impressive but cars that sound like Vaccuum Cleaners don't get my Rocks off!

There was nothing appropriate about your comments,
it was a thread about rule changes not your presonal likes and dislikes,
Just as there was nothing appropriate about your 1000 ft comment in the bernstine sale,

I can understand the weight and the engine size adjustments, but to define a single turbo unit spec and then commit you to using just one manufacture to supply it seems like a step too far to me.

yes
the spec i can sort of understand, cause there is severe rules regarding superchargers and none exept an opening size for turbos,
but 1 manufacturer isnt good for the sport,
I think Indy car racing has a spec turbo ?? is that one manufacturer? specing a compressor wheel and housing size isnt much different to specing rotor twist and upening size on a roots supercharger,
but much harder to police i expect thats why its been done.

Yeah I can imagine that point will be made by the NHRA to defend there decision, but I would argue that they still have to police the "and you're not allowed to modify it" portion of the rules. And this then brings you back to having to dismantle the units and would be just as hard as it would be to police the legality of a Garrett, Borg-Warner, Hitachi built to spec unit.

As a petrol head child I fell in love with drag racing, but as an adult engineer I find myself entirely disinterested in it because the NHRA seem to be held bent on keeping the sport dumbed down.
