sounds good, ErnieT.

question: is there a reason that you (or Ray) decided to go back to streetported side ports with the semi peripherals instead of using the bridge ports you had before? simplicity? too many changes? fuel? i'm just curious.

also what size semis did you go with (if you care to share)?

Ray did everything. Went with the street port because I chose to go that route. Ray wanted to go with the bridge, but I didn't want to get too crazy first go round.

Can you say what injectors are in it or at least a rounded figure of their sum if you don't want to give away too much of your tuner/ builders development?

Why did you install a 100lb/min turbo to only use 80lb/min of its flow?

842 injectors are only 1680cc when you are using CNG.

You act as if when I get on the dyno and need more injector Im screwed, lol. I'll just put larger injectors in. Really not a big deal. Like I said, Im in good hands.

The figure I'm given is 152lb/hour with petrol or the petrol substitute fluid they use N-heptane. No idea how E85 or E98 changes that.

I also do not plan on maxing out the turbo. Running about 30psi

car will be on the track this week as soon as my belts show up from simpson. I feel left out now that everones in the 9's, ill be the slow 10 second guy with oldschool hp lol

Will the e98 be beter than vpimport? I mean I know cost wise but wont overall hp suffer? I know you say you dont want to go crazy with this setup, but that means in ErnieT talk till next week when I get bored with 800rwhp.

Ray's work gets better and better with every setup he builds.

E85 and E98 are great because you will make more power with it, your intake charge temps will be super cool, it cost about $3-4 per gallon vs $13 for Q116 or $22 for pro import. BTW, I have a 20+ gallon drum, (unopened) of VP ProImport I will GIVE you if you come pick it up. PM me.
You'll use more fuel using the E85 and E98 but it'll make more power too. Glad your back!!

DAMN! Thats super nice of you!


BTW whats the advantage over Q16 to VP, just octane or does it make more power?

Glad Ray is getting to play with E85/E98 as when I bring him back down here thats what I am going to retune with! I have never driven (work, etc..) on kill mode as its too damn $$$. I save it for the track.
