Hey guys. I'm a whore for data/info. I was wondering if those of us who have put their cars on dynos could share the results. I'm curious to see what kinds of mods give what kind of power, and what kind torque curves, how soon power comes, etc.... HOWEVER, to make certain this thread is not simple dyno sheet porn/bragging (which is not a problem here, porn and brag all you want. that's PART of the fun), I'd like to put some rule that will actually make the thread useful and easier to read.... 1. L28e blocks only. i'm curious about other engines but the second people post l24, or rb engines, the whole thread will loose focus. OVERSIZED L28 welcomed (strokers and bored engines, for e.g.). 2. Each posted sheet must be accompanied by the following info, in the following format (make certain you kindof get it right, but let's not go overboard about the form here): 1- car: year, model. 2- State of the engine: stock, stock rebuilt, slight mods, heavy mods, total-batshit-crazy-overboard-modded... 3- peak power @ RPM + boost level (PSI) if applicable 4- peak torque @ RPM + boost level (PSI) if applicable 5- short list of relevant mods if applicable, INCLUDING: fuel/ignition management, high compression pistons, turbo size/type, piston oversize and whatever else you did that could make a difference. for parts that are standards and don't really contribute like intercoolers and oil pumps and what not, no need for details. For other mods, like a crazy-fucked-up-pink-shifter-with-part-of-christian-relic-inbeded, well, if it doesn't add hp, don't list it. 6- anything else you feel might HELP OR HINDER your hp figures, like for my car, it's got a megasquirt with a tune that my 5 year old probably could improve, so yeah, that does not help. IF your engine is stock, please write the mileage here! it'd be fun to see how much mileage has eaten how many hp. 7- anything else that's interesting about your engine that can have an impact on the topic. *post dyno sheet* if you actually have a paper sheet, just take a photo with your cell phone or something, and post it. just make certain it's clear. if you don't have a sheet, just the numbers, well that's not as cool, but still interesting. post it! Comment posts ARE welcomed. I mean, i'm doing this so we can look at the dyno results and then talk about them... just make certain you don't post a sheet and a comment in the same post, i guess, to keep things clean. don't be afraid to post a sheet, then comment on whatever else in another, immediate post (like, two in a row). oh yeah! all dynos are different, there are different types, and some have to be corrected for altitude and all that. yeah, yeah, sure... that's 100% right. but I'm not doing this to compare who'd got the biggest dic... ah, HP numbers! this is only to get ballpark ideas of what mods give what kind of power. All right guys. go for it! Seb. PS: if you have a pre- mod sheet and a post- mod DYNO result sheet, you AUTOMATICALLY become king of the thread. there may be more than one king. deal with it.

Hello all, I've had a 77 280z for a few months now. It's got a 75 L28e motor with the non exhaust lined head. Since then, I've converted it from automatic to 5 speed, 3.9 R200, decent paint job, etc. My friend and I were getting the car ready for a long trip (1500 miles) doing routine maintenance when we heard what sounded like rod knock. Well, a 2 hour basic maintenance trip turned into a 10:30AM to 5:30AM bottom end rebuild. This was 3 days before my 1500 mile trip. Regardless, the car made it with no issues!! Essentially, everything has been touched in this car except for the wiring. It runs great and is my daily driver. Now I'm looking for some more power. I've already done the basic stuff (auto to 5 speed, 3.9). I do like the L28 motor, but I have no issues swapping in something better. I am not looking for a crazy drag strip beast, just maybe upwards of 200whp with decent gas mileage (20+ would be great!). I know generally power and gas mileage don't go together, but I know some of the Chevy V8's can get you 28+ on the freeway. For a budget of $1000, what is the best way to go? From everything I've read, it seems an L28ET may be the best option. If I don't do a swap, will any upgrades to the L28 give significant gains within this budget? There are still intake, headers, megasquirt, cam, headwork, etc. My goals are a 'quick' daily driver, so I would prefer to keep the power band lower rather than higher. Torque improvements would also be nice. I'll be happy to give more information if necessary!

Ok so I've got some basic tire on my can now and I'm like some input on what I can expect out of the rear components in my 260 with what I want to throw at it. I have an early '74 260z with an open r200 (I THINK 3.90) diff...i believe the halfshafts/axles are out of a 280...but may be the stock ones from my car. I'm running a ~500hp(crank) 383 and a built/kitted etc TH350(shifts pretty damn hard). So far everything has held up well under pretty aggressive driving..I just put brand new street tires on it and can finally start to grab OK in 1st gear. My driveline was also custom made and should be one of the stronger parts in my drivetrain...leaving the axles as the weakest link i think. My question is this...how likely am I to hurt any of the axle parts with these street tires and my automatic? Both on the street and at the track (assuming i hook pretty well)? Have any of you broken them in the middle of a pass? (not off the line). I also would like to put maybe a 150 shot on the motor, as the motor was running on nitrous regularly in the previous car. I'd be looking to squeeze probably in 2nd gear...and I'm wondering if even that might be enough to shock one of those parts enough. Any input is greatly appreciated. Thanks!
