Damn, 5psi? My 2.2 is at 15 on a 3 inch pulley

Yeah, I'm not entirely sure why boost is so low. I managed to get almost 7psi in 2nd around 5800 rpm. But as for just spirited driving, I hardly see over 5.

What I see on my gauge is this, I'll shift from first to second, then go 50-60% throttle, boost will spike to 5 psi, then drop to around 2-3 psi, then slowly roll into 5 again. Nothing over 5 though. I'm not sure what's up.

What sensor is this? I've been working on my car all day, just got the intake manifold on and haven't done any of the wiring. Kinda hoping its not something I need to go find/buy...



EDIT: This is the 2.5 Bar Map right? Do I need both, the one on the supercharger AND on the manifold? Or can I just use 1? This has me confused.

Is your clutch slipping? Glad you found the o2 out. Double check your connections. Although the boost numbers are puzzling. What are your wot afr's?

So while in 1st through 3rd, my afr usually are at around 10.3 or so. I'm assuming that is what the tune commands at WOT. While driving on the highway I see 14.4-15.2 all the time. When I tap the throttle, in whatever gear gauge will spike to 13s then come back to 14.7ish.

I should figure out how to log afr and post up for everyone to see. As for clutch slip, I haven't noticed any yet anyway

That is for your MAP connection. You can also wire in your intake temp off of one of the plugs. That just requires you to pull a wire from you MAF and connect it to one on the MAP. There is a write up somewhere on how to do this.

That's a 2.5bar map sensor. You don't use the one on top of the supercharger. Wire in one of the wires from your MAF into one of the wires in the 2.5. I think its the yellow one from the maf can't remember lol

Chaos_Six

Okay awesome. Thanks for the replies guys. I just gotta get some heat shrink and I'll be good to go! Does anyone know if they make a plug for the top of the supercharger so that port isn't open? If not I guess I could make one. I guess I can start my wiring today after I find the write up for the MAF wire into the 2.5. Maybe Beck explains it in his build... lol

EDIT: okay the wiring is in his build but the diagram doesn't make any sense to me at all. How is the MAF/MAP wiring done? It doesn't say which colors to cut or where to splice them into...

EDIT EDIT: I'm dumb, kinda hard to understand when you don't have the MAP pigtail. LOL Sorry. -_-

There is this metal thing you can use to plug the top hole on the supercharger. Costs like maybe a dollar for a pack of 2 at lowes. Lemme see if I can find a pic

Chaos_Six

Sweet, there's a Lowe's like 3 miles from me. Its where I buy all my plastidip! :P But since I realized I didn't have a pigtail, I already bought one. Not I just gotta figure out where to get some studs for the two middle holes in the intake manifold. I was thinking about just buying the correct size threaded rod and getting 2 lock nuts.

what do you mean 2 middle holes in the intake manifold?

also this is what I used on my 2nd supercharger lol. had it on for a few months and its been fine.

I agree, which is why a wideband is my next purchase.

Chaos_Six

There' 2 holes for some long ass bolts that go into the head. Lemme find a pic and circle them

Chaos_Six

These

I wanna say its either of these 2 sizes

M8 x 1.25 x 125
M8 x 1.25 x 130

or m6 I can't remember -_- lol

silver_stig

the bolt size for those two is M6 x 1.0 x 70 mm.
the other five bolts need to be M6 x 1.0 x 25 mm.

those bolts are for the alternator.

Chaos_Six

Thanks! And I'm gonna go pick up some of those caps from lowes in a few! I just need those 2 long bolts to finish attaching the intake manifold so I can get the supercharger mounted.

Chaos_Six

Only 70mm? How will that even reach into the block?

silver_stig

get some strong washers as well.
make sure you line up the manifold nicely to the block. before you put the bolts in, make sure the holes in the block are centered with the holes in the mani. This will make sure the runners line up with the intake ports nicely.

Ahh ok i got them mixed up then. I was looking at when I reordered bolts and saw m6x1.0x75mm but thought that'd be too small.

Chaos_Six

m6x1.0x75mm then?

silver_stig

Yes. they will work.

Chaos_Six

Thank you, I just don't feel like buying a crapload of hardware. I'd rather make one trip and get the correct sizes rather than drive back and forth to the hardware store.

Started throwing P0106 the last few days. Perhaps MAP sensor is going out?

Just left work and my car was doing some hardcore bucking! It died quite a few times. I stopped at a friend's place, no idea if it will even make it home.

Any ideas?
