The drive into work was enlightening. I finally got on it some and was very pleased. It wasn't as cool as expected this morning, in the high 40's, but it was pulling hard. Traction was non-existent in 2nd gear when rolling on the throttle.
If I were to guess I would say there is an easy 30+ WHP gain.
Now for something unusual and the jury is still out on it. Once I get on it in 1st or 2nd (diminishes in 3rd) and the boost comes up above about 2 PSI there is a significant intake sound. I can't describe it but it is a low growl that emanates from up front. Think of it being the open CAI sound but deeper and a little louder. It just sounds vicious.
We'll see what others think at the meet this coming Saturday. At first I was shocked and didn't like it. But after driving and seeing that it does not occur unless 50%+ throttle is applied I am beginning to like it. Under normal driving it sounds no different than before.

I was in the garage all weekend removing parts and when it was all put back together, I started it up, let it warm up, and as I was checking for leaks, I leaned on the Ice Box, and the groaning I thought was an exhaust humm, went away. My point is there is a fair amount of resonance from the IceBox at idle, If the IC resonance is at more than 50% throttle, and inside your aluminum intake, I bet it is vicious!!

This sounds fantastic, though - it will be scary with 8psi!!!

Quite honestly, and I love power, this thing is more than enough at this point. I will try 8 PSI but may not leave it there. And BTW, it won't be as scary as the turbo at 8 PSI,

BTW, did you cut the sensor cable to get it back through the firewall?? I didn't think the connector would make it through any present openings.

Can't get away from that inherent belt drive loss.

nice work steve,
get some sticky rubber and head to the track before the hotlanta summer comes in..
are u gonna stay with the same tire setup, u might need to come up with a rwd conversion

I'm really curious at what point the engine will give way. But I really don't care to find out. I'm comfortable with the power now.

One more thing, I went for another drive to check on the car. It feels like it really needs additional revs now. The new manifold design may have acheived the intended goal, to increase top end power. It feels like the torque keeps increasing as the revs climb, never letting up or diminishing.
The dyno will certainly be interesting.

I finally got to test it on the highway on the way home today. Power was strong but that is not what I was looking for. I was watching the boost in 3rd gear pulls.
It has dropped a little but not by way of the IC. I moved the boost gauge line to before the IC and the numbers were practically the same. Prior to the IC with the stock manifold and the IMRC disconnected I would see a little over 7 PSI at the top end. It would start off at about 4 PSI down low and climb with the revs.
Now it starts at about 4.0 PSI, climbs to about 6.0 at about 4500 RPM and then trails off to about 5.0 PSI by the time I reach 7000 RPM. Since the blower is moving the same amount of air, it is cooler and the boost has dropped, the A/F ratio must have leaned out a bit. The engine is ingesting more and denser air with the same amount of fuel so it has to be going leaner. It also makes sense about the increased power. But I really need to know the A/F ratio before adding the new pulley which should take a few weeks to obtain.
In the mean time I'll continue testing.

Your belt could be slipping, you have described it to a "T". I consistantly had to over torque to 28+ ftlb to keep it from slipping. Once I got the two lockdown bolts tight, I'd back off, and re-torque the tensioner bolt to spec.
I would bet you are 0.5:1 leaner on the AFR than before the IC. I kept thinking this IC could bolt on and achieve an excelent AFR with stock tuning, and with the FMU just as it is set up from CT.

BTW, and OT, when I picked up my pulley from Payn a few weeks back, Devin told me he was out at CT the week before and saw a new TL with "at least an M90" blower stuffed into it.

I had thought that the boost curve would change with the new manifold. Based on the design it should support top end flow better which would potentially lower the boost while increasing power. I'll keep and eye on it and track the value with the e-Manage log capability. I'll also order the new pulley later today, 8 PSI should be a hoot!!!
![Big Grin](https://acurazine.com/forums/images/smilies/biggrin.gif)
I dunno, I think it may be going leaner than that. The air should be about 20% denser. I wopuldn't be sureprised if it wasn't in the low to mid 12's.

FYI, I couldn't get my car into the 12's (A/F, I mean) with the turbocharger - so you are probably making about the same power, so it might be a good idea to check your A/F's.

The new manifold design could be doing completely different things with the A/F ratio. Add to that the cooler air and it certainly should be leaner. I would be happy if it were in the 11.5:1 - 12.0:1 range right now as it gives some leway in adding pulse width where required when more boost is added.

Just a quick update:
I had been experiencing a sound at high load, low gear situations. My first thought was that it was hitting the hood. After inspection I found that was not the case as there was no evidence. I then thought it may an air velocity and resonance issue and was about to accept this being the case.
However, last night while I was attempting to remount the reservoir I noticed some wear on the coupling on the end tank. I checked the bottom of the factory strut bar and it was scratched. So I decided to remove the strut bar and see if the sound was still present. To my delight, it was completely gone and the car sounded as docile as before, except for the blower whine.
Now I will just modify my strut bar to allow for clearance. For other production systems I will be using a shorter core, 3.5 inches versus the current 4.5 inches. This will allow for stock hood clearance and more than enough room for clearing the stock strut tower brace.
