OK so if you did a 426 with all the good parts, no more than a 8.0 piston and ran a blower, your good stage IV heads and a decent cam, what kinda power could you expect on a reliable street car that could be used as a daily driver?
For me I would want it to look and sound half way stock as no be a sleeper. Could you get by with the stock exh manifolds too, and since my car is a 6 speed I guess I would need more clutch, but would the axles be OK?
Or would you go the 10.0 and higher route and no blower to make good power? I guess it all comes down to $$$s, but I was thinking if you could do a combo type build that makes good power, has a decent life expentancy, and still drives not to radical if you know what meaN
I would imagine just a 426 built like the 6.1 makes at least 125 HP more with a few goodies do to the cubes, better heads etc.
Lastly how about from the pipes on back, would the stk exh be a killer too with or without headers.
Maybe you could break down the power and options etc.
thanks!

the stock srt exhaust will flow enough to not hold back a n/a applications, athough a long tube header will make a good bit more power but still sound fairly tame mated to the stock exhaust.
as far as power goes, you can easily make 650+rwhp being conservative with tune with this motor + FI setup. but the halfshaft thing is still an unkown at this point. i think its safe to say they handle 500rwhp like a champ on sticky tires. but as far as these moster builds are going no one has really had the chance to test them out just yet. there are a few LX cars that are swaping over to the new rear end set up, hopefully they will be able to tell us wat kinda power these things can really handle.
I would really like to see the motor rubble is getting run as n/a with compression around 10.5-11. PPP has the record for n/a hemi right now at 11.08 @ 121mph with the next closest being torjan with a 11.40 @ 120. i think these stage IV motors could be in the 10's with the right supporting mods. i guess time will tell what they are really capable of
Justin hit the nail on the head. With an NA motor, stock headers are no problem. With an NA motor, you can expect 485-510rwhp through an automatic and about the same tq. That is enough to propel a 4,000lb car into the 10's NA.
As for Rubbels build, the sky is the limit. The goal is 800rwhp and if he is able to get it to hook and shift, mid 9's will not be a problem and it is a daily driver, so anything is possible.
I can understand wanting to see n/a performance but from day one we made choices based on FI engine. As far as the transmission we did the clutch and rear end, so it just seemed appropriate to complete the package with the stronger transmission. I did post some info on the stock t6060. http://www.rsgear.com/articles/2008_02.pdf
This is pretty much a no limit build. From full 10 pt roll gauge to a complete complement of Autometer Cobalt gauges, modern muscle fuel system, Techco s/c,PPP built 426 engine safety and performance were a priority over cost. There really are to many mods to list them all until the entire build is done.
After some testing hope to show what this car can do in Maple Grove this June.
