Let me know what you end up doing scaxx. I'd probably be interested.

 

Will do, I need to start looking at it soon since it sounds like the engine builder may be starting my engine in the next few weeks and once he starts it shouldn't be long till it's done.

 

Did some more stuff.





Also started working on my manifold. And a bit of Lars'.

Hope my block gets back from machine shop soon.

 

Who knows how to do the math for intercooler pipe size. Will a 2" hotside flow 450whp?

 

Maybe. Depends on boost pressure.

Figure out your volume flow peak and keep your pressure drop reasonable. You figure your volume flow by estimating the mass flow from the hp goal and taking the estimated boost for the power and compressor outlet temp to convert that mass flow to volume flow.

 

Took soviet 29psi to make 450whp. On a basically identical setup.

 

ages ago we had this discussion. sorta concluded that 2" is about tapped out at 400
the bigger restriction would be the bends and fmic core, but still, I'd probably go 2.5 and be safe
I've made 450-500 on subaru's with good tmics, and the little y-pipe is 2" at the neck before the turbo

 

Bleh. Anyone know if there will be an actual difference between 2" and 2.25"? If i can do a 2" hotside i have exactly what I need in the garage. Maybe i'll do a 2" hotside, and if i ever decide to go for glory i'll toss in a 2.5" Its only 2 pieces of pipe.

 

I don't see why not. Try it. For science

 

 

kewl. initial plan is to break the motor in. hit the dyno and see what i can get in an hour or 2. Then go back with the t5 and see what it will do at full tilt. Maybe even with some corn juice.

 

Gussetallofthethings!

Finally ran out of gas. So only did one side. Going to fill up tomorrow and keep chugging away.

 

gun be more filler on that mani than tubing.
but I aint complaining. by end of year this thing better be fast enough to scare me at mrls

 

I'm sure the car will be. Who knows if I will though.

Optimistic first track day is end of march. But I really don't see that happening unless all the stars align.

I'm slowly checking things off the list though. And as soon as the racepak gets here I will start putting the interior back together again.

 

​​​​​​​Running out of gas sucks. It always happens at the worst times.

 

​​​​​​​I actually keep 2 bottles around. In case I need to keep welding. It also lets me use one for backpurging

 

Aidan can scare you at any speed.

Here is nifty little table that shows you how much airlfow you gain with an increase in diameter. It starts to be really significant at 2".
Numbers are SCFM.

 

cool. here's my thread about it too from years ago

wtf. that is a cluster **** of a thread. I think I'm stupider after reading it. Lol.

 

this coming from the ramble master himself
Just read the link in the 1st post.
