Kamotors E30-Turbo to ITB M20

[kamotors]

yes manifold will be black one I'm done

Any benefit to putting the meth injection in the manifold vs where you had it before?

[twolitresix]

have all the parts ordered to get the car running again just waiting now :)
will be injecting meth into the manifold now.

Are your sure that this is a good point to inject? You are injecting your w/a against the manifolds airflow direction, i have a feeling that it wouldn't be distributed very well, most going into #1&6

its a 250psi pump and should get the job done fine.

SO I decided to run a vac port instead of my methanol at that location after further research and discovered my turbosmart wastegate had a bad seal and the valve does not even open more than a crack lol. I was wondering why the wastegate was soo quiet, it was basically a boost leak controlled by my boost controller

So you are going to put in a second "fuel" rail?

no just going to run it as it was before with just a pre throttle injector

found a cool callaway meth injection diagram for the e21, just thought I would share although its kinda irrelevant.

Did they use draw thru? Injected pre turbo? Wat

Why is there an H20 bung before the compressor inlet?

Water cooled turbo I would assume.

extra cooling?

Water cooling the turbo in which the water makes it into the intake system lol?

extra cooling?

Water/meth going through the compressor wheel?
How do you/can you regulate that? o.O

pre turbo water injection has been around for a while, saab used to do it on the 99 turbo i believe. It can make the compressor housing "feel" larger as well as cooling the intake charge.
great to do if you have money to replace turbos

"One reason for someone to inject at this location is the water/methanol mixture chemically alters the turbo compressor map. The water/methanol injection will dynamically shifts the compressor map of the turbo so that it has the compressor map exhibits the characteristics of a larger turbo. This sounds great but, the main issue with pre-turbo nozzle placement is what mixture can damage the compressor blade if the mixture is not properly atomized when passing through the turbo."

Learned something new.
Guessing it's old tech then.
