Max boost

[04oxfordvert]

So a new fuel station just went in down the road and they are planning E85. What is everyone running for boost on a stock long block? I have a TVS with return fuel system. Just curious what's a good boost level. No head studs. I'm thinking 21lbs.

Max Boost sounds like a super hero's name.

I'm at 20, but I have a full exhaust so it knocks down the boost a little. Are you going to switch to E85 full time? 21-22 with similar timing would be a riot.

Ya the plan would be full time when I'm in my city. Road trips I'd run my 94 tune as E85 in Canada is literally at 2 stations. Mine would be the 3rd.

Are you running a stock lower?

I need to pulley down but I’ll need injectors too. I would rather buy guns and ammo.

25 lbs or so on stock head bolts.

 

[04oxfordvert]

I'd like to go 21-23lbs I'm sure my rails be the limiting factor. Still stock

I have a lethal hat with 2 walbro 465 pumps, -8 feed to stock rails, id1000 inj and a -6 return.

I should do injectors, but I have too many other projects.

What size are yours? Mine are 80s and maxed out already.

ID1050X's. I saw 95% duty cycle on one my last logs. I do have some room to raise my fuel pressure though.

 

[04oxfordvert]

Whats your fuel system? Almost maxed 1050's now I'm thinking I may need rails and injectors.

I went with Fore L2 system. Plenty of fuel, not even close to maxing out.

Fore hat with Twin TI Auto 285 pumps (walbro 525 equivalent I believe)

Fore rails with FIC1200s @ 40psi on the regulator

I really want to do head studs and cams. I was going to do the studs when I swapped blowers and valve covers but I was on a time crunch and didn’t do it. Regretting it now

I'm thinking I'll change rails, and possibly injectors. I'd love to try the head studs, remove 1 bolt and add a stud but that just doesn't sit right with me. I'll run the way it is and possibly build a teksid once I legit have E85 be a higher compression cam build. Also want to port my TVS as I can't even hear it. Whistles at idle but zero scream at wot

I could probably do the same if I upped it 1-2 more psi…
