Just installed a few goodies on #917 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

No pics...sorry. I went conservative with the upgrades but they should be worth 60-80rwhp. The mods are as follows:

ATI/Lingenfelter lower pulley with 9.55 ring...left top pulley stock. 50 mm lower idler.
160 thermostat
NGK TR6 spark plugs
ADM Race Air intake
Lingenfelter/Rotofab Intercooler reservoir
90mm Throttle Body
Tune by local dyno tuner this week.

My test drive was uneventful and I was just checking for leaks, pulley wobble, etc. At grandma speeds and light throttle, no CEL yet.

So what was your final numbers after your tune?

Stephen12ZL1 · 10-09-2012, 11:37 AM

553hp/563tq....sae corrected. actual on a hot day was 543/553. It is waaay stronger on the street. Feels like it should have from the factory with minimal mods.

Nemisis · 10-09-2012, 11:42 AM

Based on the fact that you have an auto Id say those mods were worth about 80rwhp. I see a lot of dyno #'s on here for stock auto's around the 470 range. Nice numbers btw!

*radz28* · 10-09-2012, 12:00 PM

NICE

Stephen12ZL1 · 10-09-2012, 12:10 PM

SAE corrected stock was 478/481...so it was a nice jump. Feels great and the tires scream for mercy now. With the cooler weather, it should be running some decent times at the strip soon!

tnspd · 10-20-2012, 08:53 PM

nice numbers......why did you go with a bigger lower pulley versus a smaller upper? Also, I was told when I do get ready to MOD, if I went to a 90mm TB to use an LS2 90mm TB instead of the LS3 90mm. You ever hear of that?

Stephen12ZL1 · 10-20-2012, 09:14 PM

I went with the lower pulley because it was an easier swap and I didn't have to send out for a new snout etc. The 9.55 lower ring is close to the same boost as a 2.55 upper. Also, the ATI balancer is lighter than the stocker. I have never heard of a specific LS2 90mm TB but if they are both 90mm and bolt up just like stock with a "plug and play" wire connection, then they should perform identically. The listings on ebay say LS3 LS2 LS7 so maybe they all use the same part number. 90=90. I purchased the TB from ebay for $130ish. I felt like the more expensive choices (102mm etc) may not help much with a stock unported snout.

2012ZL1 · 10-21-2012, 12:13 PM

Is the 11.19 on drag radials?

Stephen12ZL1 · 10-21-2012, 12:20 PM

yes, of course. Traction is difficult without "sticky tires".

2012ZL1 · 10-21-2012, 12:32 PM

Tell me about it.
My trip to the track (before any mods) resulted in 13's with 2.7 - 2.8 60 fts...lol
I just thought you seemed to have pretty good stock tire times, so it wasn't a huge stretch to the 11's.
My car is a manual though and launch traction is a HUGE problem.

audiomikej · 10-21-2012, 12:42 PM

How about a pic of the new TB

Stephen12ZL1 · 10-21-2012, 01:24 PM

exactly like this

Stephen12ZL1 · 10-21-2012, 01:28 PM

you must get drag radials or your track runs will be a bust...that I can tell you with certainty.
