steve91tt Posted August 29, 2011 Share #13 Posted August 29, 2011 Madkaw, I'm 3rd and 4th all the way around the track. My track tires are a smaller circumference than stock. I'm pretty sure that effects the effective gearing.30 Ounce, The telemetry is from an iPhone app called Harry's Lap Timer. It uses the GPS, camera, compass and accelerometers in the phone. It keeps track of your braking, accelerating and corning g's, speed, lap time, etc. and compares it to the best that you have run. It will output in graphical form or in an excel spreadsheet. Incredible app. Just suction cup your phone to the car, start the app and drive. It does the rest. Link to comment Share on other sites More sharing options...
Arne Posted August 29, 2011 Share #14 Posted August 29, 2011 3.36 was standard in 4 speed 240Zs, the 3.54 was for automatics. The 3.54 became standard with 280Z manual transmissions, IIRC. Link to comment Share on other sites More sharing options...
madkaw Posted August 29, 2011 Share #15 Posted August 29, 2011 Thankyou Arne, sorry I put down missleading info. My car use to be an auto, so the number stuck I guess.3.36 -that's some tall gearing! Link to comment Share on other sites More sharing options...
Reverend Posted August 30, 2011 Share #16 Posted August 30, 2011 I want to upgrade my stock z with better exhaust but i dont want it to be too loud inside car. What should be the best option? Link to comment Share on other sites More sharing options...
steve91tt Posted August 30, 2011 Share #17 Posted August 30, 2011 It all depends what you are looking for. If you are looking for performance gains then it may be difficult to get much more out of a stock 1972 without making it siginifcantly louder. If you are trying to improve the looks under the hood then a nice coated header adds quite a bit of bling without making things too loud. Link to comment Share on other sites More sharing options...
Reverend Posted August 31, 2011 Share #18 Posted August 31, 2011 Well im looking just a slight more increase in HP's but i dont want to go def, if i make long roadtrips. Link to comment Share on other sites More sharing options...
steve91tt Posted August 31, 2011 Share #19 Posted August 31, 2011 I like these engines with a header, 2.25" exhaust, turbo muffler and resonator (like my post #5 above). Don't expect a big power increase but the car is quiet on the highway, no drone at any RPM. In fact, if anything, I would say the car is a little too quite with this setup for my taste.

robftw Posted August 31, 2011 Author Share #20 Posted August 31, 2011 I can attest that the MSA exhaust system has drone around 2000-3500 rpm range however i think a lot of it has to do with the muffler they chose.. its not so good. I'm still waiting for my 6'' magnaflow race muffler to get here, i'll be sure to post my results Link to comment Share on other sites More sharing options...
madkaw Posted September 1, 2011 Share #21 Posted September 1, 2011 I agree with Steve- of course- because his name is Steve and his set-up is similiar to mine as far as muffler and resonator-I just have two. Don't know if I would make anything different about the sound.I think the header makes the biggest gain in noise level. Link to comment Share on other sites More sharing options...

Reverend Posted September 1, 2011 Share #24 Posted September 1, 2011 Maybe i'll just buy a new header. Does it fit with stock pipe? Link to comment Share on other sites More sharing options...
