boost on built internals (need advice)

[Slow96GSR]

I am at 6500 feet. We run a vac of about 14-16 instead of at sea level with a 20-22. 20 psi here is about 25 psi at sea level. Also why we do a CR of 9:1 where as at sea level we build with a 8.5:1 to 8:1 CR. The best part is it's easier for me to come race there then for you to come race here, we have less tuning then you would. Sometime I don't have to retune that much if I go down up to 2000 feet. Hell Denver is 60 miles from here and 1500 feet lower and I don't retune anything.

sorry for the late reply..so you're saying that i shouldnt use block guard? and sleeve the block instead? o yeah and for the turbo, i cant find any good t28 in jakarta, so i bought a turbonetics t3/t4 instead.
i dont understand about the sea level...im noob u know?

[saxman]

block guards should never be used imo


If sleeving is a possibility for you, I don't think there's anybody out there that would try to suggest a block guard is a better option.


the issue with sea level is that the higher in altitude you go, the less dense the air is, so higher boost levels can be ran due to a less dense charge.

Yup, and that's why you don't see a lot of NA builds up here. Costs too much for too little gained. Get it sleeved. Dartons would be my suggestion but there are a few other options.

[guyverias]

got it. thanks all

20psi on that t28 is hot air. enough said.

hey Mr Slow96GSR,

what's your opinion of 'posting' a block as detailed by My Larry Widmer?

Is it suitable for a budget NA build (7500rpm max on a D16 block).
How about a FI D16 12psi max, 7000 rpm max.
What's the longevity of doing this on a daily driver?

Thanks.
Nick Daglis.
