Just thought I post this since S/S isn't booming with many new threads lately...

Last night my wife and I drove over to a nearby mexican town to meet my old college roommate and his wife for dinner. We did the dinner thing, and afterwards decided to head over to their house to hang out for a bit. His home is out in the country a little ways, so I followed. We were driving the G35, and my buddy and his wife were in their 09 CTS "DI". Both of our cars are rated at 306 hp, his with 258lb tq, and mine at 268. My car is considerably lighter than his however and geared much more aggressively. I believe mine is about 300 lbs lighter. He pulls over when we get on a back straight away and waves for me to pull up beside him. I do and he commences to give instructions.... "make a U-turn and we'll line 'em up, race to the bottom of the hill and then kill it"... so we do. I honked it off. We went from a dig. We stayed beside each other for the first 10mph, but once I got to 3k rpm, the G35 started pulling hard. By 50 mph, I had at least 1.5 cars on him, and by 70 another 2 lengths. Once I put that ground on him, he actually stopped my pull and stayed at a constant distance. I guess the weight issue was dissipating as the speeds increased. We shut down somewhere around 100 mph with the G35 3.5 cars or so out. He was very disappointed. He wants to supercharge it, but can't find a kit for it. I told him to forget that crap and just trade it for a V, that its not worth the 6 or 7k to do F/I just so he can run 13s.

Second run... Cobalt Vs SI Coupe.... short version... I just finished installing some poly trans bushings and went out for a test drive. I pulled up next to a new SI at a light, but honestly really didn't want to mess with him. He wanted to play though, and I couldn't resist. Only thing is, the SOB didn't give me any warning, the light went green and he slowly took off, then got up to 40 mph about a car ahead of me and punched it. I had my windows down (75 degrees here!!) and heard his "V-TAK", so I dropped down to 2nd and walked him down. It took a second, but I stopped his pull, gained the car length back, and put another car on him by 80 mph. It was interesting, but not really, lol. Hoping to get to the track tomorrow and test out these new bushings. I'm not getting any wheel hop on the street with them at all, but I'm skeptical if they'll hold of the wheel hop at the track. I hope that between the trans bushings and the solid engine mount that I can drop my 60' down to at least a 2.0, but keeping my fingers crossed for a 1.9.

 

I would take over the wifes G35, add a nice lip kit/wheels and turbo it. haha.
Good luck at the track. What are your shooting for?

 

Thats actually what she wants, lol. She wants to get back into an SUV, and if it came down to trading one of our cars, we both agree the SS would be the one to go. Her dream car is an SRT GC, but any V8 powered Cherokee would make her day. She likes the TBSS alright too. At any rate, I'm not in a good position to be doing an trading for awhile, so the SS will be in our family indefinitely, which is fine with me as long as I can keep modding it.

I'll be pretty happy with a 13.2.... of course faster than that would be even better, but I don't want to get unrealistic.

 

Have you looked into the Stu mod? Pretty much an inline tank with a drain so you can drain your system at the track at the same time adding ice water in the tank to cool everything down. Then keep ice in it for the run. Is your tune have your IC pump running on the on position? Nothing else just give it decent cool down time and bags of ice. I think that may have hurt me last two trips. Hr+ drive and I didn't get too much cool down time between getting there and the runs.

 

I've heard of of the STU mod, but haven't done it. I've thought up a few ways to basically do the same thing, but haven't followed thru... you gotta link for the stu mod?

I don't have the IC tuned in... didn't know you could do that until after I had Jeff tune it. I've been meaning to run it back up there and have him take care of that. What I did last weekend was cruise up and down the parking lot, etc after each run to cool it off. Worked pretty well. I never got heat soaked and improved ET on each pass.

 

Have you looked into the limiting chains for the front and footballs for the rear (as ghetto as it sounds) Hatrickstu and Cmiller (IIRC) both had them for their record runs. It really combats the rear weight distribution.

 

Yes to both. I'm going to try the footballs first. I'm getting a lot of squat. You can see it in that in-car vid I posted last weekend

 

Very nice! Send the blower to Posi performance and get it ported, I think they made like 30whp with no changes to the tune.

 

Where are they located, Dark?

Found them.... http://www.posiperformance.com/index...d=58&Itemid=64

I'm going to get up with them. This looks good.

 

" Our newest port that performed better than all expectations in real world testing. Car picked up 30+hp, raised the hp's peak in the rpm range so high that the car never actually hit its peak. Boost came in a little higher after the port also and never dropped off by one pound. This blower loves to be ported and we're excited to be selling it now."
IDK, the car never made a peak number? A ported blower will lower boost levels to less restriction, (just like adding a free flowing exhaust). Check out the the before dyno's it shows it completely dropping out of power way before 6.5K and the "hiccups".
