Question!  Why did you go with a boost switch versus the MAP splicing?
Because I didn't want to use a expensive controller.

these tiny turbos spool so fast that IMO you spend <1 second in anything between 5 and 10 psi. I only see those numbers sometimes in partial throttle. For a daily driver weekend warrior car, simple is better.

Got nice black zinc plated fittings from McMaster. NPTF , the F is for fuel which is a special designed thread that doesn't require pipe dope or Teflon but only the first time. If you unscrew them, the turn into regular npt and then have to use a sealant.

Pump in action. Its doing 500 ml a min at Current psi setting which I think is 150 psi. Thats 7.5 minutes for a gallon. I probably have to turn it down.

Yea so image how much juice SBS goes through with an m15 lol. I guess ill just test as is and AJP can tell me if its too much or not with the logs.

factory pump setting is between 265 and 280 psi. Asking snowperforamnce.net if I should turn it down.

It seemed excessive .. Maybe SBS can comment on his flow and pump rates?

Snow got back to me already and they recommend leaving the factory setting with the nozzle size I have.

hmmm I DISTINCTLY remember one of our regulars with a ton more mods than you and I quote a flow rate of about 1 gallon per 15/minutes.

Lets wait on SBS but 20 -30 psi pressure differences only equal about 30 ml/min. I assume his pump is fairly high pressure and he is using a m15 nozzle which is 3 times more flow than my nozzle.

The Alky Control pump pushes over 250 psi... plus as previously stated I have the M15 nozzle... I don't have a meter inline to tell me what my rate of flow is but it varies with the boost...

I know for a fact that I can max out and then some the amount of fuel the  ECU will pull which is 29% of the total fuel injected at WOT. Then my AFRs drop like a rock...

But I adjust the kit so I don't have knock... so I monitor KR... once I adjust the controller so there is no knock I am done... how much meth I am pushing? Dunno... I am sure you could do the math based on the datalogs... but I don't care...

Last log with Brad showed me holding over 255kpa (22.7 psi) with perfect fuel pressure over 2200 psi and AFRs holding nicely.

22+psi spike or constant? 

I have been thinking since the 15-psi build I was running was 'to hot' i might be able to go back to it with 30/70 meth.  That would be awesome since the 15[psi build was way more torquey and seat of the pants fun at low speeds.

Follow up edit question.  on 'Race days' are you dropping the 'on' requirement to a lower pressure/voltage?  I was wondering on track days if there would be any benefit to setting the meth switch to 4 or so pounds to start the spray when brake torquing.
