Re: 91 Galant VR4
 

I thought you put the engine on a dyno before putting it in the car?
Good luck this weekend at the track!

Re: 91 Galant VR4
 

When are you going to dyno?

Should be a beast!

Re: 91 Galant VR4
 

Tonight, was the big night on the dyno. And I wanted to engine dyno the thing but as it turns out the turbo setup would not fit without making a custom bell housing for the engine dyno. So good old AWD dynodynamincs is in order.

First off a big thanks to Shane and DB Performance for making this possible. The car did make Great power, then we found our wall, and it was 2 fold.

So I wanted to get the car back to the 650 or so it was last year so I could hammer out the 60'. Then if things were going well we could turn it up a little and see where the wall was, or the limiting factor.

So we tried a few runs at base WG pressure, or what we thought was going to be WG pressure. It ended up running 40psi with a line from the compressor housing to both WG's. I do not know why that is but the WG springs are 24psi springs, so last year it would run 26psi, so I figured it would be about 26-28psi. Not the case, here it is at 39psi and reving to almost 10k, it just keeps going and going.

So we proceeded to up the boost cut, based on the psi graph I figured it was going to run 35-38psi on WG springs. We checked with an air gun and the WG valves did move just fine. And in the end it was almost 40psi for spool up then settled at 38-39psi. This made 720 awhp, so upping the boost about 1psi from last year made 70 more ahwp.

So after all this we put in the boost controller and upped it to 45psi, the ignition cut out like a rev limiter and the car made 789 or something, then after some poking we made the 816.6 AWHP and 538 ft/lb at 45psi tappering down to 43psi at the 816hp mark and 42psi at red line. But we had to run more ignition timing to get a clean pull then we wanted to, so it lifted the head on the end of this run. But we turned it back down to 36psi and it made 689ahwp, so that will be my new base PSI, and up it a little from there to around the 720awhp as traction permits.

Then if I want more power I need a better ignition system, and a head with more deck thickness then the one I have now. The head I have on there now is decked a lot, the oil passage up into the head from the head stud hole is not very thick, and I might need to drill and weld in some supports in the deck surface of the head in between the head studs to get this thing to hold enough cylinder pressure to make the power its capable of.

I would need to up the base fuel pressure from 38psi to about 45-50psi, not a big deal with the fuel pump I have. Then up the boost to 50 some PSI and I think the car could make just over 900AWHp. But the setup has a long way to go before I could use that power, but on a dyno day it would be fun.

I will update with a Shootout mode graph at some point, this number was at 976 awhp.

Re: 91 Galant VR4
 

Awsome power! Good luck at the track. Where are you going for shake down passes?

Re: 91 Galant VR4
 

Those are NOT shootout numbers, right?

Re: 91 Galant VR4
 

Great job and numbers! For my knowledge, what indicators told you the head lifted? So what kind of plug gap are you running? On E98 mine are .015, no misfire using 300m coils with an AEM twinfire.

Re: 91 Galant VR4
 

Damn, its not easy making those numbers especially on that dyno. Nice job.

Re: 91 Galant VR4
 

Got damn John, that has got to be one hell of a ride on the highway!!!!!

Re: 91 Galant VR4
 

It pushed coolant out the overflow at the 45psi. Turned the boost back down and it wasn't pushing anymore. I think his plug gap was .013", it would cut out so bad in the upper RPMs at the higher boost that it was like hitting a revlimiter.

Re: 91 Galant VR4
 

Congrats on the number! That thing is a beast.

Damn I was up in Maple Grove last night too, would have loved to come up and check it out

Re: 91 Galant VR4
 

Sweet geebus.

Re: 91 Galant VR4
 

WOOHOO! Congrats man! Can't wait to see this thing make some passes this year!

Re: 91 Galant VR4
 

holy craaaaap. awesome!

Re: 91 Galant VR4
 

That truely is awesome. Next thing on the menu, Solid block?

Re: 91 Galant VR4
 

Way to go John

Re: 91 Galant VR4
 

Very awesome, John! I smiled when I saw the pictures appear on Facebook last night.
It's already partially hardened.

Re: 91 Galant VR4
 

Amazing numbers John. Keep it up!

Re: 91 Galant VR4
 

WOW!

Re: 91 Galant VR4
 

pure awesomeness!

Re: 91 Galant VR4
 

Hell yeah John that shit looks good, are you using a manual boost controler or using the AEM to control boost?

Re: 91 Galant VR4
 

I was going to use a nice turbo XS MBC, but the cheap DB one came threw again for me. Some day I want to put in a BCS for the AEM to control stuff.

Re: 91 Galant VR4
 

Sweetness.

Re: 91 Galant VR4
 

Are the shakedown passes happenening tomorrow at grove creek? If so what time, I really wanna be there.

Re: 91 Galant VR4
 

Jesus man, I was there right after it made t he 806 and I was blown away. I knew this car was gonna pwn but I that's damn good power. I would love a ride in it sometime :D

Re: 91 Galant VR4
 

No 60' testing is pushed off to next weekend on the 28th at Grove creek due to weather, then I hope to get back to Rock falls on June 4th to back up the 60' testing then try for some full pass testing.

If you go by the tried and true domestic fail ET and MPH snake math calculations the car could and I mean COULD run in the 8's at 157mph, but I think it has a 9.2-9.4@ 155mph in it at this power level.

Then if the 60' holds out to the head lifting power or 800+ and I have 26.5" tall slicks the car could run in the mid 8's at 165-170mph.

~John

Re: 91 Galant VR4
 

Snake math is most impressive. I predict 7's.

Re: 91 Galant VR4
 

Damn your making me want to change my weekend plans. and test my car that weekend too. I really want to see you car make some passes.

Re: 91 Galant VR4
 

Good luck this weekend at the track!

Re: 91 Galant VR4
 

I took the car out for a drive tonight. Its making the 39psi just fine, intake air temps were around 75-80deg, and it only took just under 6 seconds to go from 6600rpm in 3rd to 9000rpm in 4th.

~John

Re: 91 Galant VR4
 

I wanna ride in that bish.

I just added 2 -8 lines from the valve cover to my catch can thing. Then I added a 1.5" inlet breather filter with chrome cover.

This should help with some of the crank pressure I was seeing on the dyno and my test drive.

I still plan to head to Grove Creek this saturday for 60' testing if its not raining, we will see.

~John

Re: 91 Galant VR4
 

How did you know you were seeing excess crank pressure? Just dipstick coming out, or do you have a way to actually log/measure it?

Re: 91 Galant VR4
 

I do have another map sensor I was going to put in the crank case and see what the pressure is, but oil was blowing out the dip stick tube.

~John

Re: 91 Galant VR4
 

What time do races start at grove creek tomorrow? the evo is down for a new clutch , but i plan on being there anyhow.

Re: 91 Galant VR4
 

There test time is from 9am to 4pm. I am going to check out the weather yet again. If its not raining in the AM I am going.

~John

Re: 91 Galant VR4
 

Nice looking forward to seeing this thing in action

Re: 91 Galant VR4
 

Where are you? Its beautiful here! I'm hope I'm blind and just havnt seen you yet.

I showed up around 10:10am or something. I did get 1 run in before the car decided to break something. So it has gone 3 for 3, goes to the track and breaks something.

edit: I forgot to say it was the water pump gasket that pushed out the bottom of the water pump, wtf.

But I did run the 2nd best 60' with the car.

RT .641
60' 1.785
330 5.174
ET 9.017
MPH 59.14

This was at Grove Creek 1/8 mile. And until I have full slicks and better suspension I do not think I would go back.

I launched somewhere around 6k and hit 2nd gear and it went straight to revlimiter sping so I shut down and coasted.

I would guess it hit revlimiter spining in 1st about 3 times, when I get the laptop to work again I will down load the log.

So my next plan is to play with the 2 step settings and try to leave the line at 5500rpm or so with 10-13psi of boost.

~John

Re: 91 Galant VR4
 

Dam let us know when you figure out what broke.

Re: 91 Galant VR4
 

Its was the waterpump gasket that let go.
