am i wrong but does the latest trend of guys buying up us built and tuned in some cases record holding N20 motors make no sense at all,
do these guys realize over here they must use unleaded fuel for which those motors were not built, ,Roger Johannsson has spent years refining a system that will work well with the fia race fuel, i wondered why he bothered if it was as easy as buying one, i know nothing about pro mod N20 tuning and this is an observation based on what i see
any informed comments ?

I agree, to do something like this you would need the world's leading nitrous tuner to help you that's for sure.do these guys realize over here they must use unleaded fuel for which those motors were not built, ,Roger Johannsson has spent years refining a system that will work well with the fia race fuel, i wondered why he bothered if it was as easy as buying one, i know nothing about pro mod N20 tuning and this is an observation based on what i see

simply; if you can handle it you will running
fast and at the front.
Look at some usa teams, they run really good, so
yes this combo can work really good. ( even on unleaded fuel )
Blower combo is easier to get a decent tune for (much more knowledge availble )
Turbo combo starts to get more and more supporters, and so more knowledge availble
NOS combo, still have a very expensive engine and only a few can handle it. and those few
are not into the sharing so much
I like the high pitch sound blower cars and the NOS cars with flames are very cool to see also.
Sorry for me no banging turbo's wich have way to much advantage in the HP section compare to the other 2.

Don't be fooled by the turbo cars...more horsepower brings it's own problems. Yes, if your surname is Petty or Dillard you can make it look easy, but it's far from it. Look at racers like Chip King & Dennis Radford, clever guys that successfully ran nitrous & blower combos for years but never really got to grips with the turbo setup. Advances in engine & boost management are helping, but it doesn't make it easier than a nitrous or blown motor to get to grips with. Would you know where to start trying to map an ignition timing and boost curve ramp from scratch?fast and at the front.

Knowledge is great, but what you tend to find in pro modified is that each car has it's own requirements and "window" to make it work; engine tune, suspension settings, launch RPM, shift points, clutch or converter etc. etc. can all differ quite a lot between cars. Transferring somebody else's settings or tune-up can sometimes do nothing more than guide you down a blind alley. That's the same whether it's turbo, nitrous or blower. Having some numbers on a sheet of paper or software with a map on telling you how to make maximum power is only a small piece of the puzzle unfortunately - as the saying goes; if it was easy, everyone would be doing it. And turbo combinations in pro modified haven't exactly dominated, in fact Troy Coughlin's title was as much down to consistency as it was outright performance.
I think where nitrous cars are concerned in the UK, it's purely about personal preference. Some people are just used to nitrous and enjoy the challenge. There's no denying it can be quick if done properly, as Roger Johansson has proven, but it's definitely a tricky combination to get right...and throwing the unleaded fuel in to the mix is a pain everyone would happily live without I'm sure.
Has anyone used modern fuel injection and n20 ? I would have thought that something like a Motec would give you much finer control in comparison with a carb.
Then,surely,all fuel and gas being injected into the motor would under one control unit?
Sorry if this seems illogical ,I'm not up on modern n20 .

Pat Musi has been using this system for a long time on his engines; one of his motors currently powers the 1/8th mile world record holder using EFI. Then,surely,all fuel and gas being injected into the motor would under one control unit?

Roger Moore's new engine will have EFI in the Viper too.

Which kind of makes the argument that the turbo cars have "too much hp advantage to be compared to the other two" largely irrelevant.
I cannot see the connection between my post and your largely irrelevant ?Fact is that the turbos have a hp advantage. About 500hp. (Fia rules )The fact that only one turbo car seems to have it going does not change the facts. Or do you want to say that if someone cannot find a good setup for his car, he may have a rule that is easier on him ?
