what ever happened to the true hot rodder spirit?


I would not have know it by that name, but there must be lots of different such type
switches available. I was curious how Phil used it in a non-conventional way.

thats the idea. also ive noticed very recently (past ten years or so, maybe longer) that the kind of help you get at local auto parts stores is less and less informative, people that work there used to be epicenters of crafty shadetree mechanic knowledge and now its just anyone willing to work for seven or eight bucks an hour. the types of things available at places like kragen oreilly and advance and autozone are even dwindling. half of the sore is floor mats and shiny shit and the other half is motor oil and air filters. theres no extensive hardware sectioin, no mandrel bent piping, no brackets. damn shame home depot supplies more parts for my hot rods than all the auto parts combined.

ah the hobbs switch... modernly its used as a switch to turn things off when $#!t hits the fan, i.e.: turn off the nitrous when the fuel pressure drops, turn off the nitrous when the turbo is spooled, turn off the nitrous when the bottle pressure drops... infact its used to to turn off nitrous alot now that i think about it....

however...

using a hobbs switch on a turbo motor can do some interesing power enhancing things too. lets say i had a stock turbo drivetrain but wanted to increase the boost past the realm of capabilities for the stock fuel system but didnt want to lose my stock style driveability or my cruising comforts while in vacuum. well, i could tap the manifold and install a hobbs switch rigged to an extra injector to come on at say, 10 psi. and "tune" the combination by playing with injector size and number of injectors, for example.or staging them with multiple hobbs switches so one injector comes in at 7 psi, another at 12, another at 17, and so on.

once upon a time before the wisespread use of in car lambda (wide band and narrow band afr gauges) we would just make sure the turbo cars stayed huffing black diesel type smoke throughout the powerband at WOT so we knew we were running rich and safe.

msd used to sell a "engine knock alert system" http://www.summitracing.com/parts/msd-8964

that we could use that has a simple bar graph type (green bars, yellow bars, red bars!) to tell you when you have a dangerous amount of knock. this was a grea ignition tuning tool back in the days because it allowed you to move your timing to the threshold of detonation and have a good idea what was going on inside your combustion chamber.

when combined with another indispensable msd product, the BTM or boost timing managment system http://www.summitracing.com/parts/msd-6462/overview/

you could set up your initial timing to really wake the dead "off boost" and come into boost quicker with less lag, knowing that msd BTM would pull one, two or three degrees of timing for every pound of boost it detected (up to a total of 15* retardation) just by twisting that fancy little knob that it comes with.

let me tell you seeing a turbo six cylider eighties super car with digital dash instruments and crazy msd gizmos all over the center console and the "oh my god, why does it have twelve fuel injectors if its only six cylinders?!" made quite an impression on a younger version of me once upon a time.

im gonna glaze over the fact that everyone with turbo cars in south florida in one night shut down the airport because somehow all of the isuzu NPR trucks used for everything from baggage and cargo moving to waste management had been relieved of their T04B/E/and S turbos and of their very efficient intercoolers that fit perfect in the front of a z car. i dont condone stealing but i was young, broke, and naive and wasnt about to look a cheap deal on some parts in the mouth. nowadays theres better and cheaper stuff available new than ever so its not nearly the epidemic it once was down here.

ah but i digress...
 
Its a little before my hotrod time Phil, but a real close old friend from Grumpys generation told me. stories of how GMC 6-71, 8-71, 11-71 Roots superchargers disapeared from DetriotcDiesel engines local. All over in a few nights.
Installed on 392 Hemis, 427 BBC, & A few super huffer mouse motors.
Guys were broke.

I believe it! where theres a will theres a way! nowadays ive accumulated enough stuff that i just trade parts or labor or trade up some old rare stuff for new in demand stuff. occasionally i still gotta hit the parts counter and pay new retail too. unavoidable really... with alot of these older cars, new is new. if you look in our 69 camaro yenko tribute car, we turned some shitty green cores into bad ass black seats, if you see a before and after pic, you would congratulate me, but if you saw those seats next to something that was brand new, youd realize sometimes NEW is NEW and theres no way around it.
 
::thumbs up:: im trying to incorporate more images into my posts. you guys all have the barney style explanations down pat. ive never seen so many informative charts and graphs and tables and pics before i came to this site. even a knuckle dragger like me can be tracking the conversation.

as for gaskets i just use fel pros nowadays, got fed up shopping around for particular brand and part numbers, i modify the head to make new coolant exit routes now that didnt exist before and it alleviates all the bs at the back of the cylinder head. a buddys car saw 26-30 ps1 on a paper fel pro head gasket with ARP studs after meticulous tuning. he drove the bejesus outta that car every night and drove it to work every morning. 6-700 hp cars were getting served up like hotcakes by the little datsun. heads / cam / exhaust/ nitrous c5 corvette got destroyed outta the hole one night and decided "since you beat me from the hole i should get you easily at a 40mph roll" ok sucker, as long as your moneys green... got him upstairs too.

i watched that car do things i grew up being told were impossible, the boost he was running thru the paper head gasket, the pump gas, the turbo sizing went against all common belief, that car really turned out alot of people in a very short time.

hell one night at the 1/8th mile track here in miami he raced like 7 or 8 gt500's all with 6-800hp and parked them all, hotlapping on pump gas.

when i mentioned "meticulous tuning" earlier i meant it, alot of pats had to break for that car to become what it was... the tuning process was an entire week of hotlapping the car every night on the street with the laptop open seeing what worked and what didnt. about 500 bucks in 93 octane gas went into that tune.

I have heard those Datsuns 280Z had a strong rear end.
Take more abuse than I figured. 500Hp.
 
87-89 300zx turbos are equipped with the same 200mm ring and pinion rear thats interchangeable thru all the later datsuns except the 300 comes with LSD and a 3.70

it all depends on how you use it, ive seen guys break em with under 400 ft lbs and ive seen guys use welded one legger rears with over 500 ft lbs....
