We have used parts here from time to time that get damaged by UPS, taken off a car or whatever.

A good friend of ours just bought a used 2003 EVO8. Trent is his name. The car had misc. parts on it from other companies and some of ours. He wanted to change everything on the car that wasn't ours over to our parts as money and such allowed.

I dug around and came up with a used UPS damaged downpipe (small dent) a used offroad pipe (no idea why it was here used), a slightly dented (UPS) catback pipe and my used BR lightweight muffler off my RS. I also had a used BR MAF pipe and BR air filter kit from Jarrod's car.

There was also the used BR manual boost controller I just took off my RS.

Just so happened all these parts were what he needed to switch over the parts that were not ours on Trent's car.

The car had already been flashed by Al on a Dynojet. The car had a manual boost controller on it when it was flashed but when Trent bought the car it had no boost controller and was running the factory selonoid.

We pulled the car in and loaded it on the dyno. We then made two pulls with it an monitored AFR and boost levels.

We then took the car off the dyno and put it on the lift where we changed all the other companies parts off the car and put ours on.

Back to onto the dyno. The first pull we had the boost controller backed off all the way to get started. The car made more power/torque than it had on the base pulls even with less boost. Minimal though, 5-10 whp.

First shot at turning up the boost I went to high and it hit 25 psi. I waved Trent to stop and turned it down.

The next run I got the boost to hit 21-22 psi peak and it fell down to 19 psi at 7,000 rpm.

Below is the dyno sheet of before and after. The was a 42 whp gain and a 38 whp gain. This was with no addtional tuning. The car will benefit from a custom tune when Al comes in a few weeks.

Trent is a hell of a driver so expect to see some fast things come of this car. We may even squeeze a 20G, injectors and some ported parts on it before the next tuning session

BTW, we had a witness here for this complete testing. I am sure he will chime in on this. There were NO BS games played.

If the "right" questions come through from this I will answer them

Nice numbers dave. I am really happy to see these tests performed. I am always happy to see differences in parts, especially when i run the same tool for a living.BTW Dave if you get a second can you shoot me a call. Want to ask you a quick question. Thanks

Dave your an animal,

I kinda wish you weren't so far, i would love for you guys tune my car once i get that gt35r or "other" turbo form you.

have you had a chance to do any moretesting on the "other" turbo you mentioned a few weeks ago?

 

Which other comany's parts were these?

 

Absolutely amazing,

I'm not really too concerned with the make of the other parts, more so the the turbo that was being tested in another one of his threads.

Any new news?

 

I'm the witness david was talking about. I was amazed at the power difference. I know some poeple my make BS comments about this post or say that david is leaving something out but its simple not true. i was there from start to finish and nothing else was done but what he says. the funny thing is david accually didnt think it would make as much power as it did, they placed bets on who could get closes to the new number and david's number was lower!! Jarrod hit it right on the money. So if you want to know what your mods are going to give you in HP, jarrod knows his ****!!!! He got it right on the number!!! In one way i wish i wasnt there because after seeing that, i'm going to be spending more money to get the exhaust. it was feather light!!!!

 

Thanks for more great testing and info Dave, and you don't have to say no bs cause we trust you thanks

 

I don't know the maker of the exhaust but I am going to post a picture of it.

The downpipe on it was actually very nice. High flow 3" cat, two resonators, pretty quite, JDM style. Wasn't bad quality. It is for sale BTW.

Also off this car for sale is the HKS MAF pipe and HKS filter kit.

I have done more turbo testing but no new break throughs. The RS with the 20G on it makde 389 whp and 394 ft lbs of torque.

Any chance we might get a glimpse of the turbo your working on.

 

The turbo is just the 20G-9, same thing I have been working on for quite some time. Just tried something new with it that didn't make any difference in power.

Very very cool stuff. This is my favorite kind of post. Dyno's don't lie. I look fwd to your new turbo when the time comes. Keep up the great work and great posts!

 

Dave,
Why does the car weigh in at 3625?

 

Good Question.

PD,

There is a file that is included with your MD, it's in yours too. Go to the look up chart and see what the input weight and input HP@50mph is. These are the recommended settings for an Evolution from Mustang Dyno.

If you think about it this number is very close to being correct.

A stock EVO weighs about 3300 pounds, this is a GSR or MR, full of fuel etc. Add to that a driver and passenger and you will be over the recommended weight from MD.

Thanks Dave,
Our MD came with an old look up table.
Up to 2002
we normally use 3400
