Yes, that was the Ti-VCT limiters. This was on my S197, not my current S550. The S550s can run these cams without limiters, so the low end wouldn't look like that. I only contributed b/c no one else was posting; this is not apples-to-apples to what it would be like if you did the cams on your S550.
Ive seen guys with GT350 manifolds making 470-475whp on E-85 and from what I've seen the Cobra Jet is worth 15-20whp or so over the GT350 if it tuned correctly. I'm aiming for as close to 500whp as I can get on E-85 with the cobrajet manifold and stock cams. Once I get it street tuned for drivability and maximum ignition timing I'll strap it down to a dyno for a couple hours while I maximize gains with OP VCT tuning.
SVTP was the spot back in the S197 days. Lot of good info over there.
I was 460whp on 93, and I could for sure see the S550 (with better stock cams) get to those numbers on E85. No doubt. The CJ setup is key. Make sure to port it. There's a guy on SVTP that ported mine for ~$110. Made an extra 10whp. No brainer. Honestly, I don't recall the CJ setup losing any low end compared to the GT350 mani IF the dyno test was done with a timing curve optimized for the CJ. I know there were a couple of tests where the GT350 and the CJ were tested on the same timing to try and compare manifold to manifold.
It's all in the tune! And yes, I haven't seen the GT350 guys make as much. The CJ is ideal for optimal power numbers on these cars. IMO, at ALL rpm points. Shame one needs to use shorter motor mounts to run it.
Yea I'm at 458 sae on flex with Ported gt350 intake and headers.
I am yea. I want cams now which is why I made this thread lol. My car beat a friends FBO cj 2014 on the street before when I was on 93 so its decent.
This'll sound bad because of all of the AED hate, but he also collaborated with L&M engines to make an intake-only cam that shows NO low-end loss and is obviously cheaper than replacing four cams. IIRC, running stock springs is also fine with this cam. Maybe do the OPGs/crank sprocket/ATI Damper and this at the same time? Nice little stealth cam (won't lope). Do you have any driveline mods such as an RST+flywheel or a CF driveshaft?
I've actually been in contact with Shaun and don't have any issues with him. He also works very closely with the shop that had tuned my car.This'll sound bad because of all of the AED hate, but he also collaborated with L&M engines to make an intake-only cam that shows NO low-end loss and is obviously cheaper than replacing four cams.

So not huge gains, but also no losses. Just an idea. Either something like this or the Stage 3's will be a lot of fun. If you haven't already, do the efficiency mods. They're worth it as well (clutch/flywheel + DS). When I did the same set of mods on my S197 it picked up 3 cars on my buddy's G8 GT. It was crazy.
No need just Cut the rear part of the hood skeleton and remove the hood liner. Hood liner rubs the CJ and boss removing it adds almost 1/2" of clearance in some areas.
