Hey there, I've got the glamour photos of the pistons and rods, but I don't have them stored anywhere. If someone wants to email me and can host them, I'd be happy to send them. They turned out very nice and we kept the price down well below the $1k mark for REALLY nice stuff. In fact, engineering and the bean counters are looking at me heavily for this investment decision on our part, so do what you can to pass the word around and keep me in a job. They aren't in the 2008 catalog, but they are in the 2009 catalog.
The 10.25:1 1.625 compression height Piston part numbers are the pt0112h25 and pt112h45 depending on whether you want .025 or .045 over. Jobber is $466.31 Yes they include a REALLY awesome ring set. 1MM top Nitrided Steel, 1.2mm Napier 2nd, and 2.8mm oil ring for super oil control. Low friction but totally street, nitrous, and boost worthy. They've got a .280" tall top land, A .901 PIN, and the valve pockets are .240 deep and cut at 1.800 diameter for big valves. Only the best for you guys:) Also, If I had to give the parts a "nitrous" horse power rating, 175hp hits shouldn't be any issue with proper tuning. More than that is possible, but be careful. I'd like to see a fogger for equal mixture distribution.
Ok, so what do I expect from a piston swap. A point of compression is generally worth about 4% of your power and torque. The reduction in ring friction is REALLY going to pep these engines up. When someone gets one together, please do me that favor of turning a stock shortblock over with a inch pound torque wrench...then do the same with ours. You will find ours drops several foot pounds on a new-to-new short block comparison. The difference seems slight, but turn the crank at 7000rpm with a torquewrench and you'll get the idea of the horsepower savings. With a worn out short block, the initial numbers will be closer-but give the engine a bit of a break in and we'll pull ahead. obviously the weight difference is huge-which will help acceleration and lower the loading on the block and crank at higher rpm.
The Connecting rod part number is
DH7005BEHB6-A Jobber is $445.90 on them
The pistons are thick enough that a dish can be put in them -up to .170 deep and a diameter of 2.900 or so. This would still leave about .180" worth of material under a dish like this. This takes our -6cc flat top to about -20cc or so. I'd recommend this for guys that have modded pistons before....if you haven't and can't afford a screw up-get a custom version. Be aware when you machine the crown of a finished piston, it's possible to "spring" a skirt. Not detrimental to the part, but the skirt od changes a bit and you would want to finish hone to each piston individually. Normally I don't recommend that customers modify pistons much, but you guys have been doing it for years and know your way around. Just use your best judgement for boosted engines etc.
Also, it IS very hard to get me via a email or phone call. Summit won't be aware they have these parts until January or so, but they can be ordered as long as you have the part numbers. They'll call in to us to verify etc. etc., but it can be done. You can also call us at 800 321 1364 and ask for ANYONE in the automotive department to hook you up with these things. Mention Jobber pricing etc and have your buddy at Jiffy Lube etc. buy them for you if anyone gives you racer pricing
Good luck all! -Brian Nutter-Wiseco Piston[/img]
