Thanks for sharing. A 13" fan/cooler assembly, any ideas where you'd mount that? Sounds like a great idea. Did you scan after any runs and see what the trans temps were doing?

Also what is the L99 doing when the IAT's go up, is the pcm cutting back the timing in a big way? I noticed that with my Trailblazer SS that the timing would get dialed back a lot after just one pass. I'd have to cool it down 30 minutes or more.

Thanks! (non-denominational guy here)...

The tranny cooler would have to be mounted in front of the radiator, likely involving removal of front bumper, etc. I've seen a couple of installs on this forum that look good. But for cooling, I also have a Meziere EWP (2010+ Camaro specific) waiting to go on. Since the tranny is routed through the radiator, and the tranny cooler is in series, I figure this might help as well. The tranny cooler/fan is a B&M (70297 - http://www.summitracing.com/parts/BMM-70297/) and has a 175* thermo switch. I'll mount it after the radiator, so that if the radiator can't cool it enough, the cooler/fan may get it down to 175-180. Don't want it too cool.

Stock, the L99 is pretty much the same as any LSx motor. There's a table that pulls timing based on IAT, which can be tuned out if you like.

However, my IAT's are pretty consistent because I have the Fastlane Pipeline 4" CAI, which is basically the "down and out" style that draws air from behind the fog light. Once the car gets moving, IATs drop to ambient + 7-9* (heat off the track, I suppose). In the staging lanes it looks bad, because it's getting hot asphalt air and hot engine air, but it works well for me when moving.

In addition, regarding cooling, I did not notice a big heat soak problem. With HP Tuners, I can turn on the fans, leave the engine running, and in a few minutes, the Engine Coolant Temp will drop (from 212*+) into the 192-196* range (that I can view on the DIC).

The heat soak problem is one thing steering me away from a blower at this time. My friend with the GT500 would put ice on his Whipple for up to an hour between runs, and one run, boom, it's hot again and killing timing.

Padre, you mentioned you had a built GTO before this car. What size converter did you run in the previous car? Reason I ask is, I've been thinking that 3200 would be the smallest converter I'd potentially run, also thought a 3600. In the old LS1 4th gen days a 3200 stall was not very noticeable to me. I used to run a Yank TP4500. I did run a 4800 and then a 5500 stall in my last 4th gen, and the last converter was... unstreetable.

On the rebuilt/strengthened 4L60E, I ran a reworked stock converter with 4200 stall. I had a very aggressive EDC cam on a 408 LQ9/LS1 motor.

It ran 11.5's and cut a 1.50 sixty all day long.



It was also featured in one of the High Performance Pontiac's Pavement Pounder's Shootouts (Summer 2007).

Personally, with this build, I am not going "Max Race" on every component. It is still a daily driver and I'm hoping the mods, while not MAX on everything, are sufficient to make it a contender.

Cool video.... I had a '98 Formula that had many combos over the ten years I owned it. One early one was a 422 cid iron stroker, went 11.02@122.5 MPH that was fun.

So do you notice the 3200 at all? The L99 has a deep first gear I think.

Oh sure. It was less streetable because of the exhaust and cam (LOUD and RUMBLED) more than the torque converter.

However, don't drive a 500hp car with a 4200 stall in a 4th of July parade. Trust me on that one. 1 hour at 1 mph and I almost melted the tranny, had to bail out on the parade, oh the embarassment.

Yes, it is noticeable, especially with the L99 AFM. With the 3200 stall, it needs to rev 2000-3000 to get moving, and solidly moving at 3200. The AFM tries to engage at low speeds 1500-2200, but the engine wants to rev higher, so there's confusion.

Basically, I'm going to disable AFM in gears 1, 2, 3. That or I may be able to tweak the shifting properties.

But remember, AFM is not on manuals (yet) because it relies on the Torque Converter to smooth the transition. With the higher stall, the transition is not as smooth as it could be.

Day off today, so the JBA Shorty Headers went in.

Out with the old, in with the new (pics below). Install was pretty much as expected. Managed to do it in my backyard, by myself, without pulling the plugs. Didn't break anything as far as I can tell. I haven't started it yet because I've got a few loose ends to tie up tomorrow morning.

Fitment of the JBA Shorty Headers with the JBA High-flow Catted Midpipes is near perfect. I may want to replace the gaskets though, as they were flimsy.

Now we'll see where the gains, if any, come with Shorties. Is it the high-flow catted midpipes? Or do the Shorties also add power?

No other changes, and I'll be hitting the track Sunday afternoon in 80* clear weather.

Diameter is the same. The length of each header is designed to optimize by firing order and exhaust pulse. So the length of the short one on the driver's side doesn't matter, only that it's exhaust gas is not getting backed up by other ports. That's the theory, at least.

Oh, BTW, the weight savings is about 5lbs per side. Not much, but the lighter midpipes help too.

Thanks

Today would have been perfect, partly sunnny in the low 70's. By Sunday it should be in the low 80's. However, for me that just means a consistent baseline, as most of my major runs have been in the 80's so I can compare apples to apples.

Just did all the fitment checks and took it for a drive. I think guys who love the sound would love this with the shorties and midpipes. SO much better than the stock manifold with the midpipes. The car feels great now too.

Two problems: AFM is noisy as heck when it kicks in. Also, need to replace the cat/manifold gaskets.

Other than that, she's ready for Sunday.

I think, as is, adding timing low, I can cut a 1.6 sixty. With the Shorties and no tuning, I think I can cut a 1.6 also. Then, when I add the 3.45 rear, should be low 1.6's or better.

Alas, won't know till next week. Every track is closed for Mother's Day. :( So it'll be next week before I find out.

Guess I'll go visit mom instead.

Here are the details from today's trip.

- I am no longer a believer in AFM. Had it on the way to the track, 24.2 mpg. Disabled it on the way back, 23.6 mpg. On, I noticed surging, without it, smooth as silk. And don't get me started on the annoying rattle (made worse by my cat-back and shorties/midpipes). So, buh bye AFM!

- Light, steady rain on the way home. My Nitto 555R drag radials handle it no problem at 70 mph. But after I get 50 passes, then I won't be doing that any more.

- Out of the box, first pass, I ran a 12.308 @ 112.69, 1.706. Next up a 12.228 @ 112.95, 1.695. I was happy then and could have gone home.

- But I decided to experiment with the VVT and PE tables. No results. So I decided to fine-tune the spark. Some advance in the 2000-3000 range, pulled some at peak torque, and smoothed out the table. Most of the runs were in the 12.2's @ 112 with 1.6-1.7 sixties.

The results, 8th run of the day, as above (timeslip attached):

Sixty: 1.653
330: 5.021
1/8: 7.799 @ 88.66
1/4: 12.191 @ 112.89

Am I happy?

Next up, 3.45's and maybe a trip to the track next Sunday.

Padre

See page #1 or this post:
http://www.camaro5.com/forums/showpo...9&postcount=16

Basically, 18" TSW Nurburgrings with Nitto 555R DR's. Saves 12-14 lbs on each tire. Call Jon at BestWheelDeals (he's on the forum).
