boost question

[Swaggs]

how much boost are people runnin? I maxed out my 30 psi gauge this weekend. i saw the egt hit 1200 and let off the pedal. and thats when I blew out my shut off solenoid.

[Richie O]

34 psi on the 89 and 45 on the 93.

[soggy]

52 psi, 1600 degrees running the 1/4

[TWorline]

52psi with my S300.

[PToombs]

42 or so with my Stage IV hybrid H1C.
Don't feel bad. Almost everybody buys a 30 or 35 lb guage and changes it within year or so.

[Richie O]

Thats why I bought a 60 first. I knew a 3o would be maxed real soon.

i saw 30-32 on my baby hc1 and my ive never seen my egts touch 1200 ...my 727 hates me

I bought a 60psi gauge 1st too, but I'm almost positive I'll never see that much boost. That reminds me, I need to get my gauges installed...

[Swaggs]

alright, that makes me feel better.. anyone do any head work like studs or gasket to hold the extra pressure? I know when i got my gauge first installed before any mods, i was maxing at like 13 pounds.. which seems so low. makes you laugh at the kids in hondas who turbo their civic and are running 3-4 pounds..
hah.

im runnin 40 max on a hx35. i do have head studs and firerings but thats just for assurance when i get the s300 and/or if i go to twins.

[dpuckett]

I ran 40+ on a nonIC 91 with reused head bolts and a PDR HX35/18.

I wouldn't worry about that very much at 30psi, but about 35psi is all I would feel comfortable with on a stock gasket and bolts. You can, however, retorque the head, and have it hold a little better. A guy on here did that and it held 60+psi o boost for a while before he blew a headgasket.


Speaking of Joel, anyone ever hear back form him after the dyno run? On the YouTube comments of his videos, the poster claims later on in the week, his truck out down 700rwhp. Not a reliable source at all, just wondering if you guys have heard anything.

On the truck in your sig with a HX40? If so I call BS ...

I run 56-58 in my truck and peg the 60psi gauge when I spray it. Ran it bone stock like that for a few months, then re-tourqed the head bolts and a week later it let go between #4 and #5. Put a new stock (.020 over) headgasket and the original head bolts tq'ed down to 135 ft/lbs. And its been good for a year... I know its only a matter of time... Next time i'm going with a head like teh one david bought.

yeah, sorry i need to update my sig. No it is in my twin truck.. I would call BS on a stock injector hx-40 combo also. That one would hit 40-45 and the turbo did not last long!
