What oct. fuel do they need ? I can't find any info on line, I can't even find a list of motors he sells just a bunch of parts. Is there a secret web site I can't find ?

Ever tried this one?

They dont list his 825 and only his NA motor says 92 oct. I hope he has it setup to run on 89 oct. like most of the other builders are doing.

Keith Eickert is with Lightning Performance Group. You can give him a call about the 825 engine. Not all of the engines are listed on the website. His number is 217-415-9568.

I would just call him???? But I think it is safe to say almost any Blower motor making 850hp is going to be 92oct,

when I had his 675's in the A.T. they ran on 92..The 825's were in a 04 43 Nor-Tech and if I remember correctly..same..92.. I always ran 93..

Thats what I was thinking, I will call him and see if it's still that way. I hope he made some changes to run on 89. He needs too since there are other builders with over 1000 hp on 89. There are two boats I am looking at with his 825's and it's too hard to get 92oct all the time.

It was a strong motor.. that 43 NT ran 96mph.. another buddy had 3 in a 45 Sonic.. always ran good.. not the same for 675's..not enough R&D.

call and check, on a efi with knock sensors you might be able to run 89, should pick it up [knock[ and cut the timing back some until you get the 92 in it

Who are the builders making over a 1000 hp on 89 octane fuel?
