Turbo Tech

[motorhead]

Totally unrelated - but I finally figured out the math in HPtuners to adjust for EQ Error during Power Enrichment.  Just have to tweak it to filter by RPM.  I love my WB02s in Lambda - the output is so simple.  Simple MAF tweaks under WOT here we come!

Stock ECM = Stock Chip, right? Right?! PS. I flash my own.

I love solutions. Especially when they work.

You might be shocked to know that I am a HUGE beer nerd...

As in, stand outside of breweries all night in line waiting for special beers to be released...

I bought my turbo by selling 5 bottles of rare beer for $1,350... 3 of them were worth $975 alone..

Nobody has even mentioned vgt's or twin scroll technology.

Actually, you did!  Twin scrolls are amazing, that is my next turbo.  I just don't want to redo the piping.

You mean like these??

Not a beer snob, but I do like to build things


...that build things.

Maybe it is because of my time spent at Humboldt state,,,but that sure does look like a giant bong....

[earlbrown]

My neighbor thought the same thing when I was building it...


There is a built in thumper in the bottom so it could be used as a bong as long as the low octane condensate drain is plugged.

It'd take one hellova set of lungs though.  lol

I think we should start on exducers and exhaust housings now and how that influences the power band and converter stall speed and efficiency.

The exducer size isn't as critical as it used to be. The converter type, the level of port work on the heads, fuel type used, and camshaft selection play a more critical role on the spool up than the exducer size.


Even with a large exhaust housing, if those 4 parameters are optimized, you can still have a quick spooling turbo.

[/size]Tyler, Reeds car comes in at 3807. Is that with him in it...or out? My car comes in at 3475...with me in it. Every 100 hundred pounds is worth a tenth of a second. I run my car at 23 PSI with the high and low 02's coming in at 800 and the timing at 32/26 with VP 112 with the 60 foot coming in at 1.70 and staging last and the car runs 7 flat all day at 100. You can do the math what that turbo would do in my car at 23 PSI...and 300-400 pounds lighter.

If you had that turbo you'd be seriously screaming down the track... I'd love to see what you run with it!

Tyler...what brand of exhaust housing on Reeds turbo? Size? Any word on intercooler?

For the 3 bolt exhaust housings it is similar to a PTE housing. I believe Reed and Limit actually get their housings from the same place. Typically .63 and .85 AR.


For the 4 bolt housings there are too many to type...you have open housings, twin scroll housings, etc...


Intercooler... dude..I luv ya man, but I won't have anything for you until my engine is built and in the car... UNLESS someone is willing to be sent the fmic and make the mounts and piping, and I will pay them to do so...


The Treadstone FMIC guy is taking a long, long time...shit better be cheap for the piping...


I'm starting to work on the intercooler article btw...this thing may take some time...

Curious as to the IC Reed has in his car for the run he made. My bad...lol! Reed pretty much has the same mule I have. You can see where I'm going with this. Doing my homework...

I have to ask him some questions on a turbo I sent in for a rebuild. If I remember, I will ask him for you.

[BoostedRPS]

So I am writing this Intercooler article, and I am wondering what you guys would like me to touch on in this thing?


So far I have the definitions and explanations of a lot of the common terms associated with intercoolers, but nothing else.


Any input for what you'd like to see is welcome.


Thank you.

Thanks. Will check my e-mail in the morning.

Tradeoffs? backpressure vs?  effect of the air mass? myths?
