SS 1le should be able to keep up with the Mach 1 and 15-18 non-r gt350 (gt350 will smoke it on straight aways though).

When you say M2/3/4 I’m assuming you mean the current Gen. Remeber the ss 1le came out closer to the prior Gen m cars and the SS 1le smokes those cars aside from the M2 CS and whatever the special M3/4 is called.

I do agree with you though that Chevy should have given a power bump to the SS 1le. If Ford can do it Chevy should have as well. It is definitely a bit underpowered especially against cars that put up similar times on road courses.

GT350s absolutely don't smoke me on the straights. I've been surprised how slow they are for their rated hp. Also, M2Cs are right there with me and the CS is faster.


Otherwise if you're talking about keeping up with GT3, a $250k Camaro will beat them, I've seen GT4R race cars on sale for a little over $100k. Ok, not a fair fight but I want one, unfortunately out of my budget right now... They are about 3250 lbs and 500 hp with a sequential 6sp.

So much want of the GT4R, Im hoping I can make that happen in the next 3-5 years.

I find that extremely hard to believe. Only reason I can think of is they aren’t downshifting to a low enough gear to be in their power band. Both cars weigh about the same except the gt350 makes 70 more HP and it pulls all the way to red line whereas our cars die at like 5,800. I just test drove one and did a few highway pulls in it and to me it felt noticeably faster from 80+ mph. Only other thing I can think of is you’re getting on power sooner then they are which I can 100% see happening.

Here are 3 GPS speed comparisons for fun.....

My stock motor and tune (with suspension mods) vs a new 992 GT3 (non RS) same lap time

(GT3 Green)




My ZLE against the same 992

(GT3 Black)



My SLE vs my ZLE

That is really cool to see, thank you! Looks like the ZLE is about 10 mph faster than an SS 1le at the end of the long straight if I’m interpreting the data correctly.

loving this thread so far

Sure, you can boost the power of the LT1 and put in in the ballpark of the LT4, but at what risk to reliability? You are, after all, talking about repeatedly wringing it out on the track.

a heads cam LT1 will be in same HP territory as a stock LT4 and i would argue the heads cam car would be more reliable and faster.

[wakespeak]

LT1 has variable valve timing. Switching to slicks or SC3Rs will have a better payback depending on the track. The Camaro has advantages with its great brakes.

Do some research on YouTube for comps on your track. My guess is you'll find several examples of slower straight line cars faster than "super cars" because of set up, tires, brakes, seats, driving.

I would go as far to say a well built h/c fbo SS should destroy a stock zl1 on a straight.
Just fbo should be within a car in the 1/4.

I almost went that route.... the 2 issues i had were:

1) Cost - it was basically 20k+- to go from all stock to a proper heads/cam/exhaust package.

2) There is still the 4th/5th gear grand canyon gap.

Thank god i'm not the only one that notices that.


Car falls on it's face at 140 cuz of fricking 5th ratio.

[Badmojo]

Just switch to Hoosier R7 tires, add a flex fuel sensor, and get tuned for E85.

Ken

cost is subjective though.

I can't argue the 4/5 gearing. I would love to put a 10spd in my car someday.
