Message: [QUOTE="SkySki Jason, post: 78454, member: 1118"] You will be feeding fuel from both ends of each head with (2) stock PSD pumps and will be able to purge any air introduced by flushing one-way thru the heads, back to fuel tank, before shutting truck off. Fuel pressure in the heads will be monitored. I keep hearing people say to go with 250/200's instead of 238/100's - same price, but the 200's can be tuned down to perform like 100's. Some still say the 200's won't be good in cooold weather and WILL smoke with heavy throttle, even in 'mild' tunes. Also, 200's should produce lower EGT's (and better MPG's?). The OP lives in NJ and uses his truck to plow snow. Will 250/200's be happy puttering around in that climate? Is it better to just stick with 238/100's or even 80% nozzles? Especially since with PMR's he prolly shouldn't open the 200's very far anyway? Pocket is looking for about the same HP level, but it seems he has a whole bunch of extra fuel available at that level. I understand the concept of getting the fuel in there faster, but aren't we also limited to some extent by 'minimum' PW? Isn't that why vanderchevy and pockets trucks smell like raw diesel at idle and smoke/haze under light load (before charger spools)? Wouldn't THAT be indicative of poor fuel economy? Also, in the long term wouldn't that 'rich' idle contribute to coking/carbon build-up? (like plowing in a parking lot - never working the engine hard) What are the honest drawbacks of a 250/200 over a 238/100 for a guy who plows snow, pulls a camper and wants to go faster at the dragstrip a couple times/yr?
