Very nice work bud. What compression are the Mahle's then? That's some good power if they are the 9:1's.

Bet she's a hoot to drive now, hard to get the power down I bet?
And with regards to the MAP sensor, I thought they were good to 1 bar?

I'm using mine for 9psi on my SC build. Unless the 5th gen ones are different?

Amazing work though bud. I just don't see why more people don't boost there Preludes?

Re: SiR Si 5th Gen TURBO
Cheers for the comments guys
It was a little hairy. But I haven't really had a chance to see the difference in power gotta get out in the dry.....


The Mahle's are an interesting one, they are the low comp gold series, now the guy who I brought the engine from insisted that they were 8.5:1 but I dont think that you can get that on the gold series, I think they are the 9:1, but either way they seem to be doing the job nicelynucleustylzlude wrote:![]()

Yeah getting the power down is a bit more of a drama now, perticaully as is was absolutly chucking down with rain when I picked it up yesterday.nucleustylzlude wrote:![]()

The map sensor on the h22 is required to read vacuum so the stated pressure includes the vacuum range. The rated range of the standard sensor is 1.75bar, so it will read from 0bar (full vacuum) up to equal to atmospheric pressure (1bar) and then contine to read 'boost pressure' above atmosphere to 0.75bar, giving the full range of 1.75bar. So 0.75bar is the max boost it can see which is 10.8PSI which is why mine was just on the upper limit at 10psinucleustylzlude wrote:![]()
