I have seen several stroker big bore with a PD S/C develop similar RWHP to a Cobra block.

Why are we not seeing higher RWHP from the stroker big bores?

I think it depends on whose car you're looking at. You may not want more HP depending on what you have for axles, tranny work if any, etc. There's only a certain ammount you can make safely without upgading the rest of the drivetrain.

If Fordnuts 690rwhp from 17psi on 93 octane does not impress you, Im not sure what will.

Are you forgetting Marauders have 20% less HP numbers as compared to a Cobra?

^^I think FordNut also has the R100 trans which probably soaks up a couple more ponies as well.

Brian's car and motor build is without question awesome. With the boost and big bore motor, serious RWHP. I just want to see it put it to the ground at the track. That is in my opinion where it counts. But thats me.

The same with Mongoose's car. With a mega built motor, only Martyo has proven the power can bring an extreme low ET so far. Myself and Sherman are the only cars with a 4.6 motor (I think). And Sherman's ET is going to be beat shortly;). No offense to the guys with big built motors in a Marauder, I think it is cool and respect the amount of work,effort and money it takes to build those motors.:beer: Been there and done (doing) that. But take them babies to the track and get it done. :banana2:

Thanks for the kudos, it's actually on 91 octane...

I have seen a particular combination that several have bought with a Twin Screw PD S/C that only make 550RWHP.

Based on their mods it appears money was not a limiting factor.

I cannot figure out why they would spend all that extra money on a big bore stroker and Twin Screw to develop RWHP what can be done for less than 1/2 the costs.

I agree Billy. Maybe it is a mine is bigger than yours thingy:rolleyes: (JK). As it is well known in drag racing circles, all the HP in the world is great on a dyno slip, but really means nothing at the track.

Hey, Tom or doing shoot out this year?

Hopefully. Missed last year, but if all goes right and a couple of other guys from Florida go, I probably will make it. At least that is the plan now.

You going?

"Myself and Sherman are the only cars with a 4.6 motor (I think)." I do think there is another 4.6 running out there that is in the low 10's that IS NOT juiced!

Sorry bout that;). Honestly did not know if you were stroked or not. You are indeed a major true 4.6 contender with or without juice. It will be interesting:beer:.

Hey Steve! Haven't seen you post lately, been meaning to check with you to see if you're going to run at SSHS10. Better get some practice!

Yes, Brian I'll be there. It'll be interesting...I haven't drove the car in almost a year. Had some surgery and was unable to drive for some time.....

IIRC Lidio did a Big Bore Stroker, 10:1cr, mild crower cams no head work with a Trilogy SC @ 13lbs and that combo produced 580rwhp on 93oct?

There are a lot of variables as well.

The Big Bore Stroker is only part of the equation. Compression, cams, head work, intake, exhaust, fuels, power adder, boost etc. Fact is you can make big power with a very nice torque curve with less boost on a BBS setup. Yes you can make the same peak hp with a 281 lower compression and higher boost. However, I like the idea of maximizing your motors potential then going with a power adder at a lower boost level down the line.

For the person looking at the 4-600rwhp range maybe the BBS isnt your best bang for your buck option; Aluminator + SC of choice will get you their.

But as Lidio put it:

"But for the guy looking to get into a little something more, along with stroking when getting into a new forged short. Or have considered a 5.4L engine conversion. Then this new FRP modular block and its potential, is something worthy of some attention..........this new block in my opining is something very interesting to consider if the budget allows when looking into a replacement motor in a 4.6L application. "

Pulled 536.8 hp and 538.8 ft lbs, Lyshlom w/a 3.0 cog producing 13.7 lbs of boost. I was rather disappointed to find that on the second run it falls way off to only 513.5 hp with 534.7 ft lbs. 302 c.i.Forged STROKER w/ported street heat heads MM Methanol #1, 6 gallon Meth fuel cell in trunk,SCT 90MM MAF, Powder Coated Timming Chain & Valve Covers, GT Coil Covers, Addco sway bars, 4:10 gear.Uranium Warp Drive Mosler Diff Girdle, Trans Rear Lube Mod, Aluminum Metal Mtrix DS. FMS Trans Pan K&N Aircharger,Garmin NUVI,Wheelan 75w Strobes.Wig-Wag Headlamps. Bradshaw Bros transmission ,Triple disc 3ooo stall. Super Duty trans cooler.

What am I not seeing. A Cobra Reman is a fraction of what this cost.
