6258? The unseen unicorn of solstice efr turbos? Or is it the 6758?
I say this because I asked paw and sf here for dyno results on the 6258 a long long time ago. They knew of none and none have ever surfaced, not even someone doing a solstice 6258.
I really want to see performance/dyno results for the 6258. Can paw source efr's again?
Yes, it is a 6258. A 6258 on a stock LNF will put out around 375whp/400wtq with the boost limited to save pistons. On forged pistons and E47, 400whp/425wtq is pretty easy to do. There's not a huge difference in the 6258 and the 6758 until you get to 6k or so. If the car doesn't have valve springs and updated lash adjusters, you can't go much higher than that anyway. Between the two EFR's, the power limit down low is pretty much the same, limited by fueling and engine mods, not the actual turbo size difference.
I am aware of Norms splitters for the stock bumpers but, I have an RK bumper. Thanks for the reply's Sly Bob & LowLife1. If anyone comes across any info. regarding the splitter for the RK bumper, I'd appreciate it.
thanks

I'd assume the 6258 spins up quicker. The physics of being smaller...

The 6758 will do 30psi at 3600rpm in a 4th gear pull. The 6258 will do 30psi at 3450/3500rpm in the same 4th gear pull. The 6258 is kind of an "orphan" because the spool speed is so close to the bigger 6758, but lacks the top end airflow. The only reason this particular LNF has the smaller 6258 is because it was easier to get it allowed for the World Challenge Series. They originally ok'd the BNR 2871, but it's results were so bad they let them use the smaller EFR to get the car more competitive with the others in the series GTS class.
Anyone looking at putting an EFR on an LNF that isn't governed by racing rules shouldn't bother with the smaller 6258. (IMHO) The 6758 spools insanely fast as it is.
Shelby GT500 Super Snake With New Wide-Body Kit Debuts In Detroit
Excerpts:
The kit, which is officially known as the “Wide Body Street Edition,” consists of wider front and rear fenders. There’s now so much room that owners will be able to install up to 355-wide tires at the rear.
the new wide-body kit has been developed to fit any Mustang dating back to the 2005 model year.
I for one would love to have more flare around the wheels.

It's not just a car, it's a lifestyle and a community.
Soon as I win the lotto I'm in. I understand Norm's got a lot on his plate but just trying to keep interest alive. I believe the Pitbull widebody is a legitimate alternative to all the Shelby Cobra's kit cars out there, plus it could help Kappa donor car values continuing falling into oblivion.
I agree with Factory Five position. They acknowledge Shelby contribution while at the same time understanding that if not for Cobra kit car community the interest in the Cobra wouldn't continue to be alive, popular, and Cobra originals so highly valued and sought after.

Nice, I didn't have wide enough plastic (free) to make one like yours.
I'm curious as to how both of you attached your splitter.
Alex did one for ASP (Autocross class) last year and I'm sure it will continue on his new FP build. I haven't done one yet.. but have the materials around to do so.

Mine is attached with normal plastic Push Pins, some 3/16 x 5/8" and some 1/4 x 1".
I've only tested to double double nickel.

If I went wider, I would need some end supports so they would not wave!
Visited Norms this past week and got a chance to look at the widebody he's building to use as the basis for widebody molds. Pics doesn't do it justice. Rear looks like it easily going to accept 315 to 325 tires. Fronts maybe 285 to 305s. Told him once it's completed it should give the Cobra kit market a legitimate modern alternative.
No completion timeframe for the kit but hopefully there is a future for Solstice's Pitbull kit cars, and it should indirectly help with used Solstice's resale values.
The Pitbull could also elevate Kappa's in car enthusiast minds the same way Cobra kit cars elevated the OEM Cobra.

Is he making the front skinny and the rear wide?
I ask because you can already fit 315's in the front, without wheel spacers. I do it all the time on the autocross course. Rears accept 315's, but need 1" spacer and longer studs. I'd love to have something that covers up the tires a bit and looks more aggressive back there.
Still looking forward to seeing this and Norm's shop. I race about 20 mins. from his place, and all these years never stopped by. I'm missing out.
