Ok fellas, back again with yet another question.

Ok so im doin my eagle/vitara build in my d series, no block guard, no sleeves, just rods and pistons, and no head work.

Questions- How much boost can the engine handle safely and last me a few years, and how much boost can a factory map sensor read since I dont have anymore money to dump into the hatch rite now?

Thanks for the help guys.

 

is this a different car than your other thread? i thought you already had a 3bar tuned on hondata?

regardless, the stock map only reads to about 10.2-10.7psi. after that you are pulling fuel and timing values from the last column which can become unsafe as boost pressure continues to increase. ex: you are running 15psi but the ecu is only adding fuel/timing like you were still at 10

 

get a good tune and run 10psi at most. depending on how much you on it you can get 2 yrs . get a honddata s 300 they work great and have tons of protection

 

No, this is his actual car, the other is of his friends car.

 

Exactly.

Moral of the stock Map Sensor story is don't run anymore than 10psi. Put a boost cut at 10.0000 Psi in whatever program you are using and don't go over it.

Trying to push it on a stock map sensor without a boost cut is leaving the car unprotected if the WG line pops off/melts and you spike to 25 psi or so.

 

my obd0 map sensor never reported boost over 8.6psi. not sure why.

just get another map sensor they are like $60.

 

learned that from you in the first place

 

ok I decided to buy a block guard so I did, golden eagle. How many lbs of boost could I run safely with a 3 bar map sesor?

 

1000psi ... lol i'm j/k matt, hoping you can run your 16psi
