Single or Twins in the Extreme Modified class?

Looking to set up a car for the class. Are they pretty well evened out at this point, or does one have a distinct advantage over the other?

That would be a good question for Kenny Dutwieler or someone at his level. I think MOST people are biased to what they have with no actual comparison between the two.

With that said, go with twins, It will look faster!

Dont set your plans in stone yet...... some of the rules might be changing

yes rules havent been set and if there is going to be a series is still in debate.

but as of last year the twins could slightly outpower the single

In current configuration, 60's will outpower the single setups. Also since the rules are generic alot of tricks can be done

Jose would be called for those tricks That I was sure of.

The question was just kind of generic. I know what path I want to take. It sucks if the rules are changing. I think if you kept the rules the same for a second year, it's more inviting. Although i would like to see carbs allowed cause i want to do a blow through... just cause... haha.

not sure if the rules will change or not yet, still in debate.
most likely some rules may change but more likely in outlaw.

im hoping to see them allow the large frame turbos in the EM class possibly with a weight penalty

Problem with allowing T6 flange stuff is that it can make 200 more hp over the T4 stuff with single setups... it gets tricky.

So what are the quickest cars running on a T4 turbo? Probably going 88 mm right?

fash00

iTrader: (10)

still limit it to 80 mm wheels

smokinHawk

iTrader: (48)

82mm was the old limit

JZ 97 SS 1500

An 80 with T6 flange would be competitive. An 82mm T4 unit is not.

Jose, you feel that an 80mm/T6 is equivalent to the twin 60mm/T4 setup? How are you comparing the two, just curious.

Honestly, we are targetting a 9.0 ET for that class, to keep entries competitive. You should be able to reach that goal with either setup as the rules are currently written. If cars start going quicker, they will need to carry more weight to slow them down. Yes, that is brutal, but that is class racing for you.

Yeah, looking at the GT47-80 and new S80, it will make around 1300-1375hp depending on the unit chosen. A pair of standard 60's with p-trims on T4's will support 1200-1250 easy, and trick units will support even more (~1300+hp easily).

As for 9.0 target, that can be done with alot less unit when the car is purposely built.

Just using simple geometry, it would take a single 85 mm to compete with twin 60's.

A T4 flanged 88mm could make 1200hp. NMRA Drag radial allows a 85mm T6 flanged turbo and the class record is like a 8.3@161mph for that kind of setup. I think that is at like 3300 raceweight too.

Go single because twins aren't allowed in many other classes besides ls1tech.

Please allow up to 80 T6's i know theres a few of use out there

Wether or not they do im still going to keep my T6 flanged unit..... they should allow it but do like a 100lb weight penelty or something like that..... my car was built fr me and not a class... if it fits... its does i gues and ill race in it next yr. If not ill still be racing.....
