Was the post turbo also post intercooler?

 

wow interesting. u mix ur 50/50 by weight or volume?

 

Yes.

 

Volume. Get yourself some VP methanol, most dirtbike/offroading places carry it.

Many years ago I tried water only pre-compressor with a stock intercooler and couldn't get the temps to drop. Then I swapped to 100% meth and they can rocking down( 23psi on a To4B)...
You usually don't see a temp drop with water only with a good intercooler.

Also on a side note when I changed the 500cc jet to pre compressor only, the discharge temps right off of the turbo dropped from 120C to 60C...

We are going to add a 200cc jet upfront in addition to the 500cc jet post intercooler and hit the dyno, hopefully next week...

 

The intercooler is pulling most the heat with the 30/70 ai helping to pull it down further.

 

so for 50/50 by weight for one gallon

it would be 56 oz of meth
and 45oz of water?

 

something like that.

 

on previous post,,, did i say post turbo,Dummy,

I meant pre turbo W/I is hot setup.
I have an old turbo book, printed 1978, and some guys at Bonneville were using Preturb.

go figure how tech just disappears, and then shows up again, 30yrs later.

 

ya ronbros3, I hear ya on that. The way I got sold on AI was listening to a 60 year old guy talk about his 4door turbo Dodge Omni that smoked Cameros...

 

Your updates on pre and post turbo operation got me to go ahead and order the additional parts for dual nozzle operation. I'm running the original Coolingmist Varicool system. It shipped with 380cc and 760cc jets. I figure I can add the 380cc pre turbo. The 760 has been post intercooler pre throttle body.

How are the plugs holding up with that much water? I was using 100% meth before and had a leak develop at the pump. I've been wanting to go water since that happened.

 

Plugs have been holding up just fine.

I added a fmic to that red fd that used to have the XS power stock mount location.
Turned the boost up to 16psi and the car never sees above 32C in 27C ambient temps. Car doesn't have an ambient air intake either. So adding a good FMIC in addition to turning up the boost 4 psi cut the intake temps in half...

 

thats insane! again with 50/50 mixture?

 

Yes 50/50. It doesn't have an ambient air intake either, I have it shielded somewhat however..

This car is running the bigger Apexi unit too; I believe its basically a To4S wheel..

 

thats amazing, congrats!

 

i found a place that sells meth but no VP and 40 bux for 5 gallons. does it matter that its not VP?

 

not at all.

 

cool, i asked him if it was pure meth he said yes, think he said the only difference was one had lube in it or something. its in a speed shop in town

 

premix negates the need for lube.
