New S/C Roush 427R Vs. Cammed SS
#21
No offense, but it seems to me that the dude in the roush could not drive...Maybe he's "only" got 427 crank hp, so thats probally 375rw, you claim you have 405 N/A...im not seeing that with the mods you've got, you'd need H/C/I and you'd have a good engine and great tune to pull those numbers with 62cc chambers...even if you do have 405rwhp, the guy in the roush still has more usable power because his torque curve is so immediate and flat with that twin screw blower...in other words, even if you do make a shade more peak power, that cars gonna still be a bitch, because the roush makes more power almost everywhere but peak, and a lot more power under 3500rpm...Like i said, i dont think the guy could drive, not calling you a liar, bit if you want to know which car is really faster, run him on a roll at 60mph and see what happens, it would probally be a different story..
good call on the "twin screw" too

Heads, cam AND intake with a GREAT tune and GREAT engine to hit 405rwhp?
With just those two comments you've shown you know JACK **** about the LS1 platform and all LSX platforms for that matter.
As was said before, the 427R was lucky to even stay as close as he did and if the race were to be extended into 3rd gear and on, the OP would have probably pulled bus lengths. You're talking about a car that has the ability to trap 108-110 to a car that has the ability to trap 115-116.

The two post above mine (including one from a Mustang guy) have already educated you enough so I'm not going to go into your entire post, but I guarantee from a 60 roll it would have been VERY bad for the Roush. I started pulling him in second and really started to walk him once I nailed third. I let off around 90 because I was still in city limits and I had proven my point. If we would have gone 60-120 I think me putting at least a car and a half on him would not be surprising at all. I've done a little reaserch on these cars and they look to be a high 12 second car at best.

I didn't read the whole thing, but I just wanted to say that from a dig on the street I took a "427R" two out of three times from a dig with only headers and a lid. Both of us were shifting. Pretty close all three times.
I thought they were 427 cid's at the time and thought the dude was just a worthless driver (or was shifting too low in RPMs). Seems I was only right about one of my asumptions.

You have to remember he probably still pissed off that he paid nearly 50K for a car that will get spanked by a car that hasn't been produced for 6 years and is fairly cheaap to acquire and mod. There is a Saleen around here I have been itching to lay waste to because of the same thing. Arrogent ******* that paid to much for a slow car. It does look nice though.

A 405rwhp car beat a 360 +/- rwhp car.
Many bolt-on/cammed LS1's hit 360-420 rwhp.
More then enough to take down a stock 427R.
Good kill to the OP.
I have seen a couple of those cars in life and they are sharp cars.
I like the way the Saleen's look to.

I'm on the west coast. I'm not overly concerned with any of them. The worst that will happen is I'll get beat and if you race and aren't prepared for that you shouldn't be racing. I doubt it will happen but it could.

It's not fast and I never said it was. I just stated that I'm not too worried about getting beat by a Saleen. If I do O-well I got to have fun and hopefully the guy in the Saleen does too. Same thing I said before maybe this wording is a little better though.

mustang=375rwhp, 3650+lbs compared to 400+rwhp and 3300lbs
you do the math

Way to steal my thunder
I'm guessing they are a high 12 car at best. MAYBE a mid 12 second car with a great driver. It was damn close all through first and second but I started walking by him pretty good at the top of second and through third.
I'm jetted for a 150 shot, but have yet to spray anywhere but the dyno. I'm having issues with my window switch and I just got my car back from the tuner late Friday night so I haven't had time to even mess with it.

I didn't mean it to sound like that.
Just saying that they're not worth the money people pay for them.
