Toggle switch hot wired to the battery just like you would put in a race car. With the A1000 size pump you only need one. I didn't know if anyone was running one on the stock relay setup. I don't want to use a twin pump setup I only need an extra 100lph to be safe.

 

Update

I did some logging and wanted to update this. This is E85 with a MAFT and logging 2 byte at just 25psi of boost.
309 load @ 7K
330 calculated load
93% IDC @ 7K RC1000 scaled at 750 53psi base fuel pressure
2440 2 byte Air flow @ 25psi

I hope I can get the IDC's down with 1200's 93% is too high. If your looking at a SC61 or the HTA35R's and plan on running E85 you might want to buy 1200cc injectors as a minimum.

 

You still got 10 more psi to go for that turbo to "Wake up" LOL

 

93% on evoscan is still safe. From everything I've ever seen it reads about 10% low.

 

Yea I've seen Evoscan have some far fetched log's before I was hopping it was reading high rather than lower. Even at 80% at 25psi I don't have any safety margin. I would like to see 80% @ 35psi the car is just stupid fast at 30psi.
