SS on the Autobahn

I think the gearing is the issue. You go down to a 3.42 and that should buy you an extra 10+ mph -- it certainly sounds like you have the power to support more.
Depending on the tire you're running, the difference between a 3.73 M6 and a 3.42 M6 at 5,800 rpm is 160 mph vs. 175 mph.

something is up...i have a 99 z28 stock auto w/2.73s and a cutout only. I've been to 140 mph and it wasn't that hard to get there. Your talking around 150 more wheel horsepower lower geared and being a stick... defiantly should be up there pretty good. Hell I was in a 04 GTO that had a ProCharger pushing a little less than 500 to the wheels and we hit over 155 mph in it. Much heavier and less aero dynamic car too.

I've got my SS in Germany with me and after much talking to and learning from other car guys here, I have gotten out on the autobahn and opened her all the way up. After several runs, a change from all season tires to Kumho summer tires, with a passenger and without, full tank of fuel and less than half, air conditioning on and off, I am unable to get my SS beyond 160mph.
At 150, I have noticed an increase of wind noise on the windshield, though does not happen all the time. I think an issue may be the hood scoop, or at least part of the issue. My hood is no longer functional, I have the intake redirected to come from the bottom of the car, right in front of the radiator. This means that I would be able to switch hoods (SS to Z28, would that work?) and, hopefully, need no further modifications.
Please, if you are going to tell me that it is unsafe or stupid or whatever to drive at that speed, please realize that I have had my vehicle inspected by Germans who work on and inspect high performance autos, that I don't drive that fast by other autos, I have taken graduate level safety courses and I live and breathe safety (thank you US Army Command Safety courses).
So, does anyone have any ideas on how to allow me to go faster (without the obvious of power adders)? My mods are listed below, and I have 485 rwhp and 470ish rwtq. I don't wish to modify the engine any further. And my brakes are straight from Sam Strano, the pads and rotors, and I am able to slow or stop in a hurry.
Thanks for your help. I hope to get some vids posted soon. Although, it does get old (and tiring) driving long distances at 140 for a sustained period, so I can't promise the vids will be too exciting.

Who tuned your car?

The stock limiter is 160mph, my guess is it's still there...your car should be able to do well over 160 with your HP/TQ

The Autobahn sounds like a fun drive. I've read other posts on the board were F-body owners have taken their machines to Bonneville to wind out their cars.
Cool!

Just got to the office. Here it goes...
I remember this thread. I'll have to look it up again. My alignment was done in the states (UMI Road Race K-Member). The guy put a 'race style' alignment on it. He knew I was taking it to Germany.
Can't loose the mirrors. Must be driveable. It is my DD. And yes. I get lots of looks. Older folks look at me with disgust (kinda loud exhaust), but younger people (and the ladies) seem to smile and like it. Oh, my neighbors don't like me.
I can go from 50mph in sixth, yes sixth gear, all the way to 160mph with no hesitation. Sure it takes longer, but it is getting old shifting all the time. Fifth takes me to top speed, and shifting to sixth I do not loose any speed. I don't really pay too much attention to the rpm's, I try to watch the road.
See above.
3.73s, I am pretty sure they're not hurting me. But thanks for your input.
I just need to get a camera man that doesn't scare easily. It sure is fun driving here. The culture seems to really be in tune with driving.
I guess I'll need to get a gps. Maybe that is the issue.
Heidelburg. The guy I replaced is now the commander of the EMAT there. I took his old company. I need to get down there to visit him. PM me your #, maybe we can hit the autobahn.
I'll take a look at that site. I think I am already a member, but it has been a while.
All internals for my short block (from Scoggin' Dickey *plug*) are Compstar. This thing is solid. Rev limiter is set at 6700, tuned by Sean at LG Motorsports. Idles at 900, I shift at 1800 (in town), power curve hits at 3200ish and pulls like a raped ape until Sir Isaac Newton says to stop.
Thanks everyone for the input. The weather this weekend looks nice enough to hit the road. Maybe I can get some vids for you all.
There is a thread in the roadracing section that discusses this in detail. Aero, tires, alignment, brakes, etc. are discussed in detailed specifically for high speed Autobahn driving.
Here is a link: https://ls1tech.com/forums/road-raci...n-driving.html
Enjoy!

BTW, my Blazer will be here soon, a week or two. It will then become my DD. With that in mind, would you guys switch to the Strano springs? Would lowering the car bring my top end speed up?
Thanks.

Kind of on the same topic: does anyone have a recommendation for where to buy a copy of HP Tuners? What all do I need to get?
Thanks

I don't get that 'light' or 'floating' feel while driving at speed. The Koni 4/4's are amazing. I have the Strano springs, but they are not installed, so I am running the stock springs. The minimum ride hight clearance is 11 cm, and with the stock springs, I am at 11.1 cm, with the left header being the lowest point of the car. I could install the Strano springs, but with parking here, it just is not feasible. For those that don't know, parking in town is, more often than not, half on a curb, half on the street. And driving onto the military installations, with the gates and speed bumps, I would probably rip off or destroy something under the car.

I would think the lower you go you will decrease the drag coefficient but it would be so minimal at 1.25" drop that it would not be noticeable.....

edit: looks like it's the limiter. Anyone with hptuners can remove it.
