Oh I know. But I know several dynos and tuners here where I am will use correction factors between 1.1 and 1.3 because of altitude to get what the numbers would be on the perfect day with no humidity and at sea level and claim those as real numbers.

Almost 125 whp difference between what they actually make and what their sheet tells them.

 

Wow that's pretty crooked...

 

How much do you believe Dynojet is off from true crank HP? I was under the impression that adding the 12 or so % to my mustang dyno results was indicative of what to expect for that as dynojet is to be more accurate.

I guess what asking is how do I calculate HP at crank from mustang reading then

 

And thanks to everyone who has been chiming in I appreciate all the help!

 

Op your numbers on 93 are awesome.i made 365 on E85 same dyno

 

Devin remarked that my car surprised him and said I was probably in his top 10% of power yield to mod cars and that it was going to build really well so I'm really excited for the future. I intend to keep using that dyno though to monitor results accurately as I continue the build

 

Thats the best thing you could do by sticking with the same dyno since you have a baseline on their dyno for your mods, now as you add you know how much more you have added. Also someone correct me if I'm wrong but I know with rear wheel drive cars I have owned before there's about 15-18% loss to thru the drivetrain to wheels on a dyno jet and I thought awd cars were more in the 20% or little more. My evo when stock put down about 240 awhp and I have heard that mitsubishi underrates the hp # and it's actually closer to 300 crank hp. Bottom line is all that matters is stick with the same dyno and see the increase in hp/trq with your added mods

 

I was under a similar impression but all the articles I've read today are scrambling my brain with conversions between dyno types and vs bhp but in nonsensical fashion.

I found a sight that estimates numbers and works similar to the 15% ish thought

I just used that link you posted and pluged in the following 375 wheel hp, manual trans, and awd and it calculated about 448 crank hp so I was pretty close, those seem similar to dyno jet #'s. Just for reference at one point with some mods I had done to my car I put down 397 awhp dyno jet and same mods on mustang dyno put down 350 awhp.

 

Don't waste your time on this man. Back in 2005 there were members in a local evo club that claimed some bogus numbers from 360-400 whp with a HKS RS intake, tbe and hks 272/264 cams. These cars would go to the local strip and run high 12 sec passes with 107-110 Mph Traps. My first tune on my 8 that I still own today and my Fiancés evo 8 were both tuned by Al back in 2005. Cars ran good at the 330-350 range they dynoed, but once we had our cars tuned by Sean Ivey in 2006 it was night and day.

What's sad their are still local tuners in my area making suckers out of these new kids or inexperienced Evo owners selling pure hype from social media feeds and videos just to sell them a basic tune to then bait them for a motor build once their engines grande. It's a cruel cycle of guy/gal buys evo. Guy/gal sees YouTube video or hears from friends about tuner-Guy/gal seeks Tuner then blows motor- Goes back to tuner and convinced for a build- can or Can't afford the build then sells car to local used car dealership that recommends this hack tuner and another sucker will start the cycle all over again.


Best thing you did was find a place your content with and just be happy with what you have

 

As others have said, chasing Al is going to be a waste of time. If you really want to disprove the number just look at the mods the car came with and look around the dyno tuning section for similar cars with similar mods. From that you can get an idea of roughly what the car should have put down. Honestly, as other's have said that's a waste of time as well since it would cost money to be able to get money back from whomever sold it to you. Sounds like you landed with a good shop, keep fixing it up and hit whatever new goal you are looking for.

 

You're trying to get money back because your car didn't make 450hp Lol ???

 

No I'm not trying to get money back. I want to know if my anger should be directed at a tuner or a fraudulent seller.

I am happy with my car, it pulls hard and feels amazing to me to the point that I had believed it may have had those numbers prior to finding out it didn't but you must understand that it is upsetting to buy a car marketed at 450 HP using a Evo IX turbo with a 10.5 Buschur Hotside to find out neither of those were true and that the tune was terrible to the point of dangerous.

I recognize that I may not be able to find out the answer to my question and that's fine because now that the car is in my hands it's getting taken care of and running great with a long and delightfully modified life ahead of it. I just think it's worth trying to see if I can get the old tune sheet.

 

Hell it'd probably cost me.more money to try and sue anyone over it then I'd make hahaha

 

I'd suggest taking personally responsibility and simply be angry with yourself. Ten minutes of research would have yielded that a stock turbo Evo on 93oct can't possibly be anywhere near 450whp. Chalk it up to a lesson learned and move on. No one put a gun to your head and forced you to buy the car. With that said, good luck with whatever you plan on doing with the car in the future.
