Turbo BS Thread

I was just introduced to the cobra head intake coupling. For those with tight quarters in front of their turbo inlet.

On an a4b6.

 

They stole my idea... Okay I plan to do the whole turbo build for ~$1000 so I can still crush their budget, but they will out power me no doubt. Marty did say it's the easiest turbo he had ever done though... https://youtu.be/cOYc0OHhqY4?si=xWyoB2zFcg4ZZKO1

 

Was actually just starting to watch this episode, before perusing the forum. Lol

 

There was a v6 Camry offered with a SC and 5spd. On my bucket list.

 

There is a kid that had a RAV4 like that too that he gutted and it rips lol

 

Around 14 with a 5250lb truck. 5psi 4.88 and 33s. The 9.6 was pulling my 3500lb boat 50 miles. I once almost got 22mpg doing 45mph for the whole tank. I keep adding weight reinforcing things so those days are long gone.

 

Damn. I should keep a log like that. Would be good to see trends over time.

 

Just a real simple Google form that records the responses to a spreadsheet. I use another form for maintenance also. Easy to keep track of mileage and what needs replaced.

 

I finally got my IC properly mounted

 

Even better idea with the Google form. Makes it nice and easy

 

Got a different spinny thing to try out. Gt3076r with .82 Tial housing.

 

All the midrange. I forgot, your rods upgraded?

 

All stock engine.

 

Probably ideal. If anyone wants to ever send me a compressor graph I can plot your expected range and tell you if you're sizing correctly or not

You wanting that one mocked up?

 

Yeah, curious what it looks like on the 3.4

 

K, actually a bit large but you are in the max efficiency range.

Assumptions:
0.8 VE
2psi @ 1500
4 @ 2000
6 @ 2500
10 @ 3000
14 @ 3500
20 @ 4000+ and capped

VE under WOT can be assumed to be lower approaching 0 (so shift left slightly), can be assumed to raise over 100% after low boost (shift right slightly)

 

He probably spools up even earlier than those targets. That is roughly where I spool at with roughly the same size turbo behind a 2.4. I do have a .63 hot side. Eats up that entire curve.

 

That spool rate is about where my 35r sits now with .82 housing and boost controller.
