Yeah i guess they still have to prove you didn't use it as a paper weight. Either way just order it through a retailer and have them ship it discreetly like they did with me.
I mean like I “inquired” about them doing.

Since I already had one blower unit replaced back in May and have another 17 months left on my warranty, I think I'll wait. However, I may go ahead and buy the HBP now so I have it on hand when it comes time to do the install. Or would that be too tempting? ![Big Grin](https://acurazine.com/forums/images/smilies/biggrin.gif)

I don't think Chap has his S/C yet.
And I really don't think it would be economical to mix 100 octane with the 91 octane to raise your overall octane rating. 100 octane gets pricey. Based on rough, quick calculations, you'd need a 30%/70% mix of 100/91 octane to achieve 93 octane.

Everything else is sitting here except that one tiny component. The S/C kit.
And the HBP is gonna be put on from the start.

But Glenn i was talking with Jorge (SCTL-SS) and he ran the base pulley on his S/C TLS for quite a few months. He then eventually went with the HBP and he said he felt more of a difference in going from the Base Pulley to the HBP then from going N/A to FI.

Might be a bit exaggerated but I’m sure the added boost can be felt.

Who's running the HBP in CA? I have it sitting on the shelf because of the 91 octane concerns. I'd really like to know if it's working out.
I got the same story from CT on the HBP and warranty question. I bought it through VR though. The dealer would not touch it even though they did the SC install.

~ 4 psi with the stock pulley
automatic runs high 13's, 6mt should run ~ mid 13's w/ decent traction (which is a problem on street tires)
blower runs from ~ $3K used to ~ $4K new plus install.
do a search on comptech supercharger, s/c, blower etc.

That's why i'm trying to find a regular supply of 100 octane and i'll spend the $$ to run at 93-94 everyday.

I guess the 13.6 came from the Comptech unit then. Although 13.6 is pretty fast for only 102 MPH. DR's or slicks?
Allmotor's N/A run on slicks was a 13.5 @ 102.

TypeS1976 (Eric) and myself both found detonation around the 5.5RPM range, but we disconnected the IMRC and not experienced any knock since.. I know you got octane issues out there, but you can atleast try,,

What octane gas were you using when you had this?

What's the downside to disconnecting the IMRC on the SCd car ??

Unpulgging the IMRC makes no overall big change in power. It is a little higher in some regions and a little lower in opthers. But overall the plots look nearly the same and peak power it essentially the same.
One other benefit of disconnecting the IMRC is the power delivery is smoother. You don't get a lull and then increase in the 4k range

Would unplugging the IMRC cause your gas mileage to take a big hit. Wouldn't this have the effect of adding boost always, even from idle to the lower RPMs when only partial throttle is applied?

No, it would not affect normal mileage. It may slightly affect WOT mileage but that would probably not be measureabe.
Remember, the butterfly valve is set to open at 3800 RPM. Below that it is closed along with being closed all of the time with it disconnected. So normal driving sees no difference. What has been found is that the boost increases some just after the VTEC change over with it unplugged. This will increase fuel pressure some which is probably why the pinging was eliminated. It is also how there could be a slight decrease in fuel economy.
However, that is only at WOT above 5k revs and would only amount to a small differnce in fuel usage. Considering most are WOT above 5k revs less than 1% of the time, say 0.1% (1 second per 1000 seconds) and using maybe 5% more fuel your fuel economy would change 0.005%.

The butterfly opens when the pressure increases... With it disconnected it is CLOSED all the time. the forced induction from the supercharger is ramming the air right into the runners instead of the air bouncing around in the intake manifold then going into the runners.
Glen I have been running 93 (a few times on long road trips in cooler weather) and mostly 94 octance since the day I installed my S/C'er but after i disconnected the IMRC I have not had any detonation at the higher RPM range... it was very slight.. you really had to listen for it at the time.

So, removing the plates, that the imrc control would increase midrange response? Thought I read abut all this before somewhere
