Tried this on the evo 7 settings and it came out with 303whp and 296wtq. (20psi of boost, 99ron fuel (uk ron)
....still dont understand why I'm getting such high a figure? (temp and air pressure settings are accurate for when I did the log.)

There might be an error with the metric conversions perhaps, though I was pretty sure it was tested out ages ago and had no issues. Are you fairly CERTAIN your car isn't lighter than you are entering into the simulator? Are the gear ratios listed in the simulator the same as your car (I could have done them wrong for your model perhaps)? Also make sure the tire size entered is correct.
My evo8 put down 315whp/303wtq on a dynojet on 93 octane (U.S. Ron+Mon/2 method) with 23psi peak,20psi at redline with just a MBC, 3" TBE and open air filter.....for comparison. I know our vehicles are different.

Much appreciated guys! I couldn't be more happy with my combo i have put together for my car so far. It has a nice broad power range and spools nicely as well. Now i just need some more fuel supply and 800+WHP i don't think will be a problem AT ALL!

You still willl never take it to the track and get a number that matters.

Until then ill just keep driving it daily and busting **** out on the street on the weekends. That's what it was built to do anyways. And hell if i take it to the track everyone will know what it traps and then that throws my street game all off.

At least YOU have traction on the street lol. I roast 3rd gear when the 60-1 kicks in with the Mirage haha. Once I get another daily driver, I might get some street legal drag radials so I can have fun on occasion on the highway when I take it out for a drive 400+whp in a 2250lb FWD car is not a good combo for grip.

Trust me Jack i feel ur pain lol. Ive had a couple colt/mirages thats where i got my screen name I had a Original 89 Turbo Colt that had around 500WHP that wouldn't hook for shat. I also had an original Turbo Mirage that i had the engine and setup that i now have down in my 91 AWD Talon.... it wouldnt move in 4th gear just hit rev limiter on street tires lol. Also had a SRT-4 that was right at 500WHP... also a tire frying machine.. as well as a few FWD Talons over 500whp.

The evo 6 isnt in the list but I have added it using the following settings -
1360kg (from mitsy manual) converted to 2998 lbs (probably heavier with junk in the car)
gear ratios - 3rd=1.407 4th=1.031 Final Drive=4.529 (from mitsy manual)
Front area= 22.82 Drag Coeff= 0.37 (from MLR)
235/45/17 tyres = 25.3in
log temp = 52f
log baro = 29.751
......is this just to do with the fact that US dyno's supposedly read higher than UK dyno's?

Did you enter all of those settings with the 'Unit of Measure' setting set to METRIC, and then try it with the 'Unit of Measure' set to IMPERIAL and see if there was any change?? That way i know the conversions are correct and that it isn't causing the issue.

I don't know really. I would assume Dynojets would be the same regardless of where they are. They seem to be the most consistent from one dyno shop to the next.

Ok thanks for checking that for me...one thing I didn't mess up I guess haha. If everything is proven to be accurate (the vehicle weight is the best thing to get confirmed by getting the car weighed) then the results in the simulator aren't too far off from actual dyno results. What are your power #'s with weather correction disabled?

oops!!!
the power is 303whp and 295wtq WITH weather correction disabled (missed that one)
comes out as 288whp and 281wtq with it enabled (which it should be)
....so its getting closer but still too high. Will have to get the car weighed sometime and enter an accurate weight.
on MLR we use a 'fudge' factor to calculate power at the fly which is 24%
so this now puts me at 379 bhp (flywheel)
and 370 lb/ft (flywheel)
We need more guys in the uk using this software and comparing to dynos here.
