I don't know. This is the first dyno I've been to that was actually measuring manifold boost. Doesn't seem like it should do that. I wonder if I'm getting some belt slip. Kinda weird though.
|
It looks like boost is about 7.5 PSI. You have an 80mm pulley don't you? I would have thought you'd be at about 10 PSI with the 80mm. How do they monitor boost PSI during the dyno?
|
They had a hose hooked to a barb on the intake manifold.
I was surprised by 7.5psi as well. At 6800rpm the blower is at about 105k. Don't have enough data points to know if that's lower than expected (the psi). |
Wouldn't the power be more illustrative of 7.5 PSI though? I would think 10 PSI out of a Rotrex on a VVT NB2 would yield more than 200 whp.
|
Oh yeah 7.5/200 seems in agreement. It seems to me I should be seeing more than 7.5 though.
I am very curious to see boost numbers with the new head. It should go down, because more flow everywhere. Probably won't see that before January though. |

the race to 200whp between Mobius and Curly continues...

I should have told him to do a run to fuel cut.

Mobius could you have a leak somewhere? and how would we find that if we wanted to check? |
Martin! Call ER, time for 2 more psi.
|
I could have a leak. Possibly the recirculation valve is bad. I will check everything with compressed air when it goes into the garage for upgrades.
At the moment the priority is to get the beer brewing stuff reassembled and get a batch of my Dunkel brewed. |

Got some dunkelweizen brewed. Twice, in fact, since the first batch was my "hey I'm brewing again after a 10 year hiatus" and there were some, umm, temperature control issues during mash. So it came out 3.1% alcohol instead of 5. SESSION BEER! Second batch came out at the target 5.1 %.
Beer stuff is now all put away though. I got a package awhile back from some dude named Dimitris, and just today I got a big package from some dude named Emilio Cervantes. Dunno what's in it. Maybe I'll check it tomorrow. Got this whole family thing I have to manage and "put first." Whatever. Dunno WTF is up with that. Like my kids are important or something. GOSH. I have added to the List of Things To Be Done: Trackspeed Oil Cooler. |
Richard why you no finish original oil cooler project?
|
I am concerned about the oil throughput of the cooler I chose and I am also concerned about having fluid flow external to the frame rails. So I have decided to move a different direction.
|
Are you doing something different than the TSE oil cooler on my car? Rx-7 core behind front bumper?
|
That's not a tse oil cooler, it's just sourced by tse using an rx7 core. They have their own kit now.
|
undahstood.
|
Wait, did you buy the one from the Theseus partout?
