Highbredcloud, I think we are over it.

Honestly, it would be cool to just see a TON of different IX dynocharts covering a huge range from mild bolt-ons to fully maxed out, high compression 500HP setups. Drag strip results, careful VDR, or actualy dyno.

Just good hard data with no more BS.

 

The -4,0 was not a shot in the dark. It was the results of probably 50 different pulls trying timing changes indepentently on the intake and exhaust (0/0, 2/0, -2/0, -4/0, 0/2, -2/2, -2/4, etc...) and it was the best HP curve without KILLING midrange. Messing with the exhaust got a little more top end but it detroyed midrange (-20 ft/lbs or more).

Sorry, I am confused all to hell! haha I bet my posts I make are the same way for other people to figure out.

This curve you posted, I'd say the red curve is the winner, do you agree? The red curve is with the cams at 0/0, right?

For your VDR charts in post #52, there is an unrealistic spike at 7000 RPM. To correct that simply lower the max RPM trim number until the spike goes away:

"MAX RPM Trim"
This feature helps to smooth out any irregularities you may have at the end of your
pull when displayed on the graph. This feature will save the last value that was
selected so its best to always selected the highest value on the drop-down list
once you've imported a new datalog file.

If you do experience irregularities with your graph (usually the last 500 RPM may
ramp up drastically or fall off suddenly), select the next lower RPM value from the
drop-down list until the irregularity goes away. These irregularities occur from
inconsistent data at the very end of your dyno pull. Usually because the last few
rows of data may have actually been AFTER you had already removed your foot
from the accelerator pedal.

 

Yeah, we are over it, the post wasn't called for and the moderators just said to stop with that type of crap.............

I believe in my very first post here I asked for other guys with small turbos to post up their sheets/builds and details. That's what I wanted to see too.

I do not believe that with as low as our dyno reads that 403/403 can be that impressive.

 

Noize...since you are capable of cleaning up and reopening the threads...can you re-open the one that started the whole madness as it had valuable info for the whole community...Myself with others have been interested between the HKS turbo...BBK...and the Green...R/Ternie was the only one that had the trubos and he provided unbiased opinion that helped with the decisions...this thread serves no purpose but to continue to bash and discredit a product tha that has not been tested...

Also if you can PM me the details of how to become a vendor on here I would appreciate it...thanks in advance...

 

drb, that isn't a spike at 7500. That's a dip at 7000 because the actual problem is I nailed the rev limiter and it jacked up the entire end of the pull. It happened the last few pulls of that day and I didn't notice until I got home to review the data. I haven't done any more testing since, for other reasons that would definitely cause a **** storm that I want nothing to do with. That's just the chart I have available. The car holds HP all the way to 8000, trust me, it is not a spike and it is a realistic number, the dip does make it look like **** though.

David, yeah, the 0,0 is the red and is what I run the car at for the improved powerband. It was 10 HP on the old setup at the 240 HP level. I never got around to testing at higher boost. The 15 I was thinking was from another local guy has the same cams and picked up 15-20 WHP with the same -4,0 timing on E85 and the 380 WHP level. I haven't tested it on my own car at this current time to verify similar gains, so it was a bad choice of words to say it would make that extra 15.

 

The other thread is open.

As far as becoming a vendor, please scroll down to the bottom and there is an "advertising" link in the center. Thanks.

 

David, 400+ from what seems to come from your dyno and the traps it ran is damn impressive on the stock turbo, much less on 93 octane.

That is the point really. What ever the reason, be it setup or jsut flat out tuning, the 400HP and 124 mph traps you have posted are impressive. Impressive to the point of people needing to realize that what you have obtained is not a normal out come but a damn good goal to strive for.

Maybe I'm wrong. How many other people have pulled 124mph traps in a full weight (non-RS) EVO on 93 octane and the stock IX turbo?

 

I'll have a dyno up shortly of my stock turbo set up. I just bought and EMS so I'm hoping for good things on 93!

 

I hope I don't get anyone bunched up by my comment, but I wonder how much of it has to do with the use of the AEM EMS. Knock control is completely different than the stock ECU (my guess is less sensitive), and that combined with forged pistons and rods could allow timing and AFR numbers that give some solid gains over the stock ECU where we are slaves to knocksum. Guess it would be interesting to see the timing curve for that Evo.

 

That was discussed in here already mrfred and I'd say is part of the equation for sure. Remember though, 40,000 miles like this, so it's not like it's a one hit wonder that exploded after the tune. I tune a car and how it makes it's final pull is how it leaves and is meant to be driven.

Timing at peak torque was only about 2 degrees with only about 7 on the same load line at redline.

 

Dave, the dyno posted on page 1 of the evo 8 is running only 2 degrees at peak torque, and 7 at redline?

I was about to start experimenting with the psi/timing combos, to see if higher boost and lower timing will give me better power then higher timing and lower boost. My mods are similar to the one you posted.

 

Yes that is correct on the amount of timing.

 

I tried to link some other some other threads I found with other good stock turbo graphs on pump gas, for some reason I can't get the links to work through this ipad I am using. So I bumped the threads. Jestr made 400 on a MD in Florida on the stock turbo and pump gas too. There were some other 380+ charts I bumped too. Anyway.

 

By a request, I posted a bunch of stock turbo charts here:
