EVO X dyno comparisons

[David Buschur]

We are starting to get a decent database of EVO X runs now. I'd like to show the baseline dyno runs of three EVO X's, bone stock.

The lowest numbers were from our personal car that had no miles on it. It also had the fuel that the car was shipped with from Japan in it only. I blame the 0 miles and piss fuel for the lowest numbers of the three cars. The other two cars in the dyno graph had about 1700 miles each on them with 93 and 94 octane in them.

Here is the dyno graph from three stock EVO X's.



Next up is our stock baseline run compared to our EVOX now with our "offroad" Stage 3 kit on the car.



Now for a bad ass EVO X set up for road racing. This is the sweetest looking EVO X I have seen. Jarrod started another thread about it. Grey with the aero package, full Robi Spec suspension and Enkei wheels. This car made great power and has our Stage 3 kit on the car.

Stage 1, Catback, air filter kit and reflash (using optional manual boost controller)
Stage 2, Upper and lower i/c pipes and MAF pipe (this car does not have the MAF pipe yet)
Stage 3, Race FMIC

**Note this car is also still on the STOCK cat and downpipe. Check out the improvements!



Last is the comparison of the stock EVO X with just a reflash, NO aftermarket parts what-so-ever. This is just timing, MIVEC, AFR and boost being adjusted in the reflash. Great bang for the buck.



The cars are really coming alive now with the tuning. Mine feels superb. If the clutch will hold up to the new found torque gains I expect to see some new times from the car this weekend.

Enjoy.

Well I wanted to see how our EVO X would do on a Dynojet so you as customers could compare our numbers to most others that have been put up on Dynojets.

I gave Tym Switzer at Switzer Perforance a call and asked if he could get me in today for a few quick runs. Want to say thanks to Tym and the fellas over there for getting me in and allowing us the time to see what we could make.

First some details. The dyno runs that we made here produced 407 whp and 341 ft lbs, that was on our Mustang Dyno AWD500SE dyno. The dyno run was done in 3rd gear, I do not use any correction factors on our dyno, ever. So the runs on our dyno would be "uncorrected". I also did the runs from 2500 rpm to 7500 rpm here on our dyno. Boost was set at a peak of 24.7 psi.

Now to the Dynojet. Same things were done. 2500-7500 rpm, 3rd gear and we ran the car uncorrected.

The first few pulls the power was not as high as I had expected. Tym suggested the boost may be off between the two dynos because our Mustang Dyno loads the car differently. Sure enough a quick check of the boost and we were only making barely 22 psi. A quick boost adjustment on the BR inline controller and the boost hit right at 25 psi. The power jumped right up to what I had hoped for.

443.23 horsepower and 383.75 ft lbs of torque. Very impressive. This is on STRAIGHT 93 octane at factory peak boost levels.

Here is the dyno sheet:



Here's the video:

WOW, I am really giving serious thought to picking up a 10 when I get out of school. Well by then they will have the XI out hahaha.

[hechtrod]

Wow, basically 40whp (50flyhp) difference between dynos. Hello!!! That basically sums up the variation from dyno to dyno perfectly. So, how does one try and estimate power at the crank/flywheel? You can't just take the typical powertrain loss (typically what? 20-25% for an awd car?), it will be the same percent different/off as when comparing dynos.
For example, if you take 25% loss at the BR dyno: 407whp/.75 = 542fly HP and on the Dynojet: 443whp/.75 = 590 fly HP.

Does each dyno have a manual or guideline to help understand crank hp?

In the end, I guess it doesn't matter. If you stick to the same dyno, you're main goal is to compare changes relative to previous runs on the same dyno.

Thanks,
Chris

David...with these new horsepower levels reached on the X, ever think about retesting the unnamed downpipe to see if there are any gains at these elevated HP levels????

[David Buschur]

I don't plan on retesting the 02 housing downpipe we tested last time, I don't have it, it's on the customers car. We are going to test a downpipe again on it when we get some time.

[Bionic Dead]

I'm thinking that there will be a difference this time. We will see

[David Buschur]

There is no calculation for flywheel horsepower on our dyno.

The EVO 8-9's were rated at let's say 275 hp. They made 215's on average on our dyno.

Hey Dave, if you come up with some upgraded clutch packs for the MR's you can try out the Dominator 2.0 and cams on my car for the comparison But I will not be raising my power levels until we can make sure it will not destroy my clutches

Well Keith.........................we don't do transmissions upgrades on auto's. We'll be waiting for someone else to do that.

Below is a dyno comparison of our EVOX.

The red line solid line is stock boost, horsepower and torque. I know it gets hard to read.

The green smaller dashed line is BR Stages 1-3, stock turbo, boost, HP and TQ.

The blue larger dashed line is BR Stages 1-3, Blouch D2 turbo, Cosworth cams, boost, HP, TQ.



We have gained 196 peak whp over stock at this point.
We have gained 105 peak ft lbs over stock at this point.

We have gained 208 whp at 6900 rpm over stock at this point.
We have gained 156 ft lbs at 6900 rpm over stock at this point.

Peak boost stock was 22.5 psi.
Peak boost with Stg 3 stock turbo was 25.8 psi
Peak boost on Blouch turbo is 24.7 psi.

The car bone stock made peak boost of 22.5 psi at 3700 rpm
The car modified with the stock turbo made peak boost of 25.8 psi at 3700 rpm
The car with the Blouch turbo and Cosworth cams makes peak boost of 24.7 psi at 4100 rpm. Compared to stock it makes 23.2 psi at 3700 rpm.

At 6900 rpm the stock car/stock turbo had 13.4 psi, loss of 9.1 psi
At 6900 rpm the Stg 3 w/stock turbo had 17.4 psi, loss of 8.4 psi
At 6900 rpm the Stg 3, Dom/Cos had 22.1 psi, loss of 2.6 psi

Gawd damn David!!

[David Buschur]

Nice power from a build today.

The car belongs to Matt, EVOX. Mod list:

BR offroad pipe
BR True Dual catback
BR manual boost controller
RC 780 cc injectors
BR upper and lower i/c pipe kit
BR Race FMIC
BR custom tune
BR air filter kit
Blouch Dominator 2.0 turbo
Cosworth MX1 cams

385 whp and 331 ft lbs of torque. Car feels nasty fast.

Thanks alot David for all the time you have invested in this car for me. The dyno graph looks sick. It has come along way in almost a year since I bought it.

You have an awsome team over there and have yet to let me down. Thanks again for the quality power producing parts. I will be back as soon as you come out with some more goodies and a clutch upgrade.

Cant wait to pick it up tomoro.

-Matt

[Bionic Dead]

Congrats on the power! What psi is the car tuned at?

[JSAV08EVOX]

Great work!!! I can't wait to get my car up to the shop for some upgrades.

[David Buschur]

Peak boost is 24.xx.

You are very welcome Matt and we do have a clutch upgrade. I've got the Exedy Twin in our car now and the new HD cerametalic is on it's way to us too.

You want us to get a clutch coming and just leave the car there?

I dont know how soon it will be but it wont be long before I am going to get one in. I will def be back to you for one sometime soon so if you want to have one there for me that would be great. I work so much its hard for me to make arrangements.

Can you think of anything else my car needs or could use to make some more power while you have it there?

You should just do a full out build , We need a Buschur Racing fully built beast Evo X around the burgh. That will make 3 BR builds to hit the streets summer 09

Oh ya by the way I have a few nice runs for you . I think you will be right in the mix of things

[David Buschur]

Nothing else out right now for the car, we are working on a few things but our car has been down with the ECU in the UK for the last month or so. Trying to help get a datalogger going for the EVOX.
