Tuned the new setup..

[Erron Spalsbury]

Changes to the new setup.
10:1 Ross forged
Dry sump system
3rd Gen Lifters
New tune
Oil cooler fan (ya, I'm listing it) LOL

Awesomesauce. Is that the Veilside front, btw? This was probably asked before, but if so, what was/were the beneficial reason(s) that you opted for it over the others?

I have been thinking about a 3582R - have only seen one person post results with it on a 6G. The 3788R also seems nice for street usage.

Hey erron, are you using a vacuum regulator or did you just cap off the PCV ports and pull max vac, and have you tested what you are pulling?

[Erron Spalsbury]

It's a totally capped system now. It pulls many inches of vac but I don't want to disclose a lot of that just yet as we did a few things to improve on that.

The front end is a low cost Certa Fit.

[Chris@Rvengeperformance]

nice power, especially for the boost

[anyonebutme]

Yea, I was told to keep it at around 12 inches and over 15 inches tends to play havoc with the oil seals, so I'm going to put on an adjustable vac valve to let in air into the heads to release some vac and help pull oil back down into the pan.

[Erron Spalsbury]

I would try it without first. The more the better when it comes to crankcase vac.

[familyMAN]

Car looks awesome! Care to post the graph?

Custom dry sump? Did you have issues with a wet sump?

[J-Groove]

Very clean race car!

It's the last image of the video.

Yes, wet sump, knocking on the door of 2g's lateral, it goes dry. No amount of baffles or overfilling will cure it. Dry sump is the way to go guys if you're wanting to do turny-turny stuff.

I sure do love this car! Great numbers, I bet the 10:1 is a lot of fun.

I wonder if the high compression is worth as much as a stroker? Pretty economically way to do it. I would've loved to do both, but being able to run 93 is useful.

Count me in as one who would like to know more about your dry sup set up when you're ready to disclose. It's on my long term to do list, but would rather be able to DIY than do the SCE route if possible.

I've often debated that question myself, especially with TD05s and E85. Curious which would have the greater impact, have to think stroker would be the way to go for TD05 if you could only choose one, but hard to say since there are so few high compression high boost builds on the 3S.

[Erron Spalsbury]

I've never had a stroker so I can't really say. I will say though, just putzin around the neighborhood here, normally I would need a few pounds of boost to get up a few of the hills and now it never even comes out the vac range. Not to mention the throttle tip in is way more "snappy" and you REALLY notice the torque out of boost. I can't wait to see the difference on the track. Unfortunately, it's snowing here in Colorado now and very cold so I'll have to wait a bit for a local track day.

Generally accepted estimate on the interwebs across various platforms is 3-4% hp gain per 1pt increase in compression. No decrease in spool but people perceive a difference because off boost hp/tq is better. Compression will help with drivability if you have radical cams with large overlap. Increasing compression is common now in turbo limitations in classed events to maximize hp per lb/min of a turbo.

Stroker adds almost 17% (23% for stroked 74) displacement which will dramatically aid in spool up and horsepower per psi. If maxing out a turbo. A 3.0 vs 3.5 at the same compression ratio should have nearly equal peak hp.

The real answer here is BOTH. More stroke and more compression:D

Assuming you can run both without detonation issues on whatever fuel you use. I think that a 10:1 3.5L should be perfectly reasonable honestly, going up beyond that might require making some sacrifices to run (full time E85, or a more or less always on meth injection?)

Erron, what were you seeing for HP and torque the last time you had it on the dyno? Aware that it will be different for a variety of reasons, just curious what you before and after is with these changes.

[oohnoo]

Awesome results for a awesome car. One of the best out there.

[Erron Spalsbury]

It was around 615 horse, same turbo, same boost, fuel, injectors, etc..
Remember, when it comes to turbo cars though, static compression doesn't really change peak hp numbers. (if boost, VE, and flow rates are equal) The majority of the HP increase came from the dry sump in this case.

[oohnoo]

I don't get it. Can you educate me as to why the dry sump would increase HP?

[Chris@Rvengeperformance]

The vacuum on the rings increases power and the crankshaft not having to cut through oil helps too.
