Re: 91 Galant VR4
 

Yeah, that thing needs tires in the worst way. Nice runs!

Re: 91 Galant VR4
 

Hell yeah john get some better 60s but if it's going to destroy 3 gear like grove creek then just keep doing what your doing!

Are you going to forum wars?

Re: 91 Galant VR4
 

Sounds like a great plan, just need to get the perfect track day to drive down that record!

Re: 91 Galant VR4
 

Well I am out for the track this weekend. I still have a mountain of safety items to take care of, and the tranny is not happy shifting into 3rd or 4th gear at high rpm at the moment.

The issue is with the solid hub twin disk clutch and shifting at 9800rpm have taken its toll on the tranny.

Lucky for me its an easy fix, but I need to drop and tear down the tranny. Here is a link to the issue, last time I was in the tranny it had broken springs in the 3/4 hub and was showing the mushroom problem a little.

So I need to tear it down and see if the springs, which were new, are now broken and then tapper the synchro ring around the dogs to prevent the mushroom affecting shifting.

On a plus I drove the car to my parents house tuesday and saturday, I gave my dad and Ryan a ride. And drove my boat on the water for the first time in 10 years.

Re: 91 Galant VR4
 

I did make it to the MAP dyno day, but just. I pulled the head off my car to replace some bent exhaust valves and drove it down there to see how the car did on an AWD DynoJet.

I replaced the 2mm oversized exhaust valves with 1mm over valves. I ended up lapping them in, which worked great and they sealed just fine.

We turned the boost down to 36psi and did some street runs on the way down there, everything looked good, if felt good on power for that boost level. We looked at the logs and made some changes, upped the boost to 40psi and the first run it miss fired a little and made just under 800AWHP at 40psi. So we added some timing where it was missing and the 2nd run was clean, 829AWHP and 554ft/lb at 40psi with a little less overall timing then it had when it was on the dyno early this year at DB Performance.

So we cooled the intercooler down and tried to up the boost again, shooting for 44psi, forgot to up the boost cut, fixed that and tried again, it missed a lot, and put down 860something.

At DB early this year at 40psi on the dyno dynamics it made 720 un corrected AWHP, and at the same boost level on the AWD Dyno Jet it made 829ahwp at the same boost, dang.

I figure a clean cooled down pull at 44psi the car would make low to mid 900's, which is right were it should be.

I should have pics and videos later this week, thanks Josh for helping tune and use your camera.

A big thanks to all the people that made this car possible: Ryan, Kyle, Josh, CP Pistons, Carrillo rods, Karl Ramm, KRAMM-LOX, Paul, Chuck at HTM, Shane at DB Performance, Jacks Trans.

Re: 91 Galant VR4
 

Holy cow john......

I thought all dynos read the same you that's what I was told.

You must have changed alot of things..;)

Looking forward to seeing you at CFR on the 9th.

Re: 91 Galant VR4
 

That's a crazy powerband for a 4202. I would think you'd have no problems digging into the 8s on slicks and the trans holding together.

Re: 91 Galant VR4
 

The car was running great. Then on the way home the keepers on the #4 cylinder #2 exhaust valve blew out. The valve dropped and some damage fallowed.

Here are the pics:

I am headed up to work to clean up the back up block and pick up my parts to finish assemble the back up motor. Then I will pull the tranny apart to fix 3rd/4th gear shifting and with any luck I will be at Cedar Falls the 9th.

Re: 91 Galant VR4
 

Damn that sucks. Get it back together I was really looking forward to seeing it at cedar falls.

Re: 91 Galant VR4
 

Oh myy.... Secks.. Pure secks.

Re: 91 Galant VR4
 

Damn. Good luck man.

Re: 91 Galant VR4
 

At least you got that neat paper weight of a valve! Haha. Sucks to hear about the car though :/

Re: 91 Galant VR4
 

Dam that sucks!

So the back up motor is a short block as of Sunday night. I have the head ready to bolt down, so when I get home tomorrow it will be a few more coats of copper spray on the head gasket, then I will tear the rest of the way into the tranny then bolt the head on before I go to bed.

~John

Re: 91 Galant VR4
 

Ugh that sucks but damn you are kicking ass getting it fixed! Keep going!

Re: 91 Galant VR4
 

That's gettin it done man. Good work.

Re: 91 Galant VR4
 

Awesome, you do good work, and do it fast!

Are those stock 2-piece valves?

Re: 91 Galant VR4
 

Hey I was sorry to hear of the failure, crazy unfortunate. I hope to see you at Cedar this weekend. I need a partner in crime to beat up on all the V8’s that will be there!

Re: 91 Galant VR4
 

No, that was a Manley 1mm over exhaust valve. The stock keepers gave up the ghost and the valve dropped at 9800rpm.

And as for going to the track this weekend, as long as the weather holds out I should be there.

Right now I am a 1 man show until things start to come together, then I will need the help to bolt it all together and get some street tuning in.

Re: 91 Galant VR4
 

John, tried to update you on dsmtimes, there was an error. I linked this thread and your big post to Brian and emailed him asking to update.

Thanks, I submitted many moons ago. I just figured the site was dead or something.

Its now finally updated. Wot.

Re: 91 Galant VR4
 

Any winter plans? Will you be making it out next year?

Re: 91 Galant VR4
 

Nothing to big right now, I will get the car out like it was. Running 40psi and driving around. I do not want to go back to the track before I have a dog box and slicks, so saving up cash is my big plan I guess. I might be at the MAP shoot out thing, we shall see.

~John

Re: 91 Galant VR4
 

Good luck saving money.

Re: 91 Galant VR4
 

Time for a small update.

The rods/pistons are back at CP Carrillo.

I am getting a hole new set of pistons. They looked at the ones I sent back and there making some changes to the design, adding more gas ports for the top ring, polishing things, and changing the outer shape to help stability and reduce skirt scuffing.

The rods will be checked in every way and new small end bushings installed.

I should have the parts back in a month or so.

As for the rest of the setup a dog box is not going to happen this year. But I will get slicks, cute, full fire suit, helmet, the new twin disk with spline drive disks, new head, new head and main studs, a back up tranny, new t belt stuff, a copper head gasket. Chassis will have a few updates, nothing major. And the plan is to work on the short track and get the 60' closer to the 1.4-1.5 range then go back to BIR and take another crack the ET record.

Re: 91 Galant VR4
 

Awesome dude. :fork: :rock:

I'm sure that you don't want to buy new pistons, but maybe an fyi that will help down the road. Ron Shearer is now working for wiseco and has released some new 10.5:1 pistons built to hold some serious power, this is basically an early release of the next version of piston, but they got really busy and just wanted to get something out they are still testing more advance features.

Good luck man.

Re: 91 Galant VR4
 

There are two thoughts on how to make power on alcohol.

9:1 worked last year so I will stay with that. I can still turn the boost up for more power.

Re: 91 Galant VR4
 

If your turbo has more boost in it then yea I wouldn't go for higher compression. I remember I asked Shane about this back when I was thinking of going 10.5:1 on my car and he said the only time it makes sense is when you are trying to max a turbo that is out of air.

Well seeing as how I don't want to get out of a stock frame I settled on 10:1.

I would be afraid of running higher compression on a setup like this. So many other parts to break, I think staying 9:1 is prolly a good idea even if you could make a bit more power on higher comp.

Hopefully its a good year for this beast.

Re: 91 Galant VR4
 

The power started to drop up top a little at 44psi. Its well known on a 2.0 and a 4202 will make over 50 psi. I think at 46-48 psi the car will be close to 4 digits.

~John

Re: 91 Galant VR4
 

There is a limit to compression I agree, but from what I've seen its closer to 11:1.1
on 4G63.

Like i said, i'm sure u don't want to buy new pistons just for that, but down the road you might consider it.

Re: 91 Galant VR4
 

I would rather run 50psi with 9.0:1 compression than 30psi with 11.0:1 compression.

Re: 91 Galant VR4
 

I'd rather run 70 psi with 7.0:1 compression than 50 psi with 9.0:1 compression or maybe go really crazy and run 100 psi with 3.0:1 compression. Everybody's doing it.

Re: 91 Galant VR4
 

Higher compression always seems like a great idea on paper...then blows up in real life.

Re: 91 Galant VR4
 

Hell yea, someone used or maybe still does make 7.5:1 compression pistons for DSMs. Boost makes more power than compression, and compression does not spool the turbo any faster.

Re: 91 Galant VR4
 

Everyone on the link forums seems to be doing ok, so good infact that wiseco is releasing 2 new lines of higher comp. pistons.

Re: 91 Galant VR4
 

Yea most new builds I have seen that run corn or race fuel always have high compression pistons and I don't see any problems popping up.

The only problem I have seen was plano evo's...doesn't mean high comp is bad.

Re: 91 Galant VR4
 

Any time you compress air it will heat up, the great thing about higher boost is that you then get to cool it down with an intercooler. When you raise the compression you do not get to cool the air down, so more heat is created. As with everything there is always a happy medium and alcohol burns cooler, so where that happy medium is... that is the question.
