What RPM does the TVS 1900 spin at for the ZL1? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

The Ratios are in the chart above in post 6.

Yes that chart has ratios, but I am uncertain if what they are claiming as "stock" (7.8" crank pulley & 3.0" SC pulley) is OEM or if that is some Lingenfelter pulley that achieves stock boost levels.

Like you already mentioned, that chart is from Lingenfelter and the chart on your site is from Metco. The one from Metco says "stock" is 8" crank & 2.85" SC. Maybe that's just what they use to get to "stock boost levels" and not OEM sizes?

Once again.. lol

Do what's proven...

2.38 pulley. ..

No damper needed..blower will live forever..
Done...

Those are OEM sizes on the LPE chart.

Metco tends to round up numbers.

Perfect. Thanks.

not to mention hydraulic power steering with a pump vs electric with the ZL1

... & when Eaton redesigned the TVS 1900 rotor finish to go into the MY12 LSA, Cadillac did not re-certify the engine power numbers but simply left the 556/551 HP/TQ numbers established for the MY09 release. With only two model years of the V2 left the approximate gains of 10/10 didn't justify the platform expense.

When does the supercharger kick in for you guys? Is it instant or at a certain RPM range? Im noticing hellcats and whipple superchargers seem to kick in instant they hit the pedal. I dont notice my supercharger whine and kicking in until 3-4 gear. During rolls, It doesnt kick in instantly it seems to be only once a certain RPM is reached

Redlineviper · 01-15-2016, 07:09 AM

I no longer have a supercharger on mine but believe a pullied 1.9 can make 10psi by 2000rpm.

Doesn't the boost gauge ramp up almost immediately when you go to WOT?

Kinda hard to look down there when you doing a certain mph lol

The computer does soften the onset of boost depending on what PTM mode your in.

This can be tuned out for instant boost.

So say I put it in second at 2000 rpm and then go WOT. Not too fast to watch the boost gauge. Mine starts ramping boost and making SC noise pretty quickly. Does yours?

EvilZL1 · 01-16-2016, 06:38 PM

Thanks everyone I noticed it does kick in but will not be heard until higher rpms and speeds. I hate that its so quiet
