Gollum Posted October 16, 2013 Share Posted October 16, 2013 Does anyone (monzter included) know if there's a way to find all these pictures still? Every time I click on one of his pictures in this thread I get an "invalid IPB path" error. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted October 16, 2013 Share Posted October 16, 2013 The pics were in his HZ album which did not migrate over to the new software HZ now uses. Maybe you could try to PM MONZTER and see if he will link you to another access he may have for the pics....

Gollum Posted October 16, 2013 Share Posted October 16, 2013 Yea, that's kind what I figured/feared. I'll shoot a PM and see if he doesn't mind digging through old pictures. Quote Link to comment Share on other sites More sharing options...
260DET Posted October 16, 2013 Share Posted October 16, 2013 As insinuated in my first reply, I agree with Jon. I've used Dynapacks (preferred) and Dynojets. Here are some of the NA L6 engines I have measured on a Dynapack (all have headers, intake and exhaust upgrades): Rebello 3.2L, triple Mikunis - 260HP Rebello 3.1L, bored SUs - 231HP 10:1 L28, medium cam, Megasquirt, no head work - 180HP Bone stock 280Z (stock manifolds, Monza exhaust) - 125HP L24 with header (stock cam, SUs, intake, air filter) - 118HP What modification do you think allow your L24 develop as much power as a Rebello 3.1L? Or for that matter as much as a Bob Sharp C production L28 engine? Thanks, Pete Dynopac is a hub dyno? Dynojet is an inertia type and a Dyno Dynamics is a retarder type. All will show different figues I believe, obviously a hub dyno will read more than a wheel on rollers dyno for a start. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 16, 2013 Share Posted October 16, 2013 I think the big thing to take from these past discussions was people with a Racing Mindset BOX must stay thinking within that BOX (also known as strict rules governing things like valve placement, size, etc...) and that touting authoritatively ANY "Racing Numbers" as any sort of "ultimate" build is foolish since they, by definition must conform to RULES that LIMIT horsepower. This engine was not built to conform to such standards, period, end of debate and comparisons between spec-racer builder-specialists, and those not constrained by such rules.

z-ya Posted October 16, 2013 Share Posted October 16, 2013 Dynopac is a hub dyno? Dynojet is an inertia type and a Dyno Dynamics is a retarder type. All will show different figues I believe, obviously a hub dyno will read more than a wheel on rollers dyno for a start. Dynapack is pod style dyno that mounts to the hubs. All the cars I listed were tested on the same dyno, on the same day. Quote Link to comment Share on other sites More sharing options...
260DET Posted October 16, 2013 Share Posted October 16, 2013 Yeh I guess that I'd better leave the perennial dyno accuracy thing alone. But, can't help myself here, some people do disrespect some US dyno figures as pony power, not horse power Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 17, 2013 Share Posted October 17, 2013 The simplest thing to do is ask if they can convert to an SAE Specification. If they can't, there can't really be complaining about anybody saying it's "pony power"! Quote Link to comment Share on other sites More sharing options...
260DET Posted October 17, 2013 Share Posted October 17, 2013 More to do with the make and type of dyno I've heard Tony although I guess some operators from anywhere give in to temptation and customer expectations. I once sort of asked my operator to push a few buttons to give me an inflated power sheet but he refused. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 18, 2013 Share Posted October 18, 2013 Any dyno can be made to show anything the operator wants. That's why I mention SAE Specification. It's an apples to apples comparison using standard math conversions to standard conditions. John C has posted the paper on it. The biggest thing is if the Dyno can be converted to SAE specs (or DIN, JIS, etc) Not all can be! Mustang, DynaPack I know can be. The Mustang manual has a section on it. Look at which Dynos the OEM's use for emissions testing, stuff like that. For years Clayton In-Ground was a golden standard, as long as you calibrated per the SAE specs at the time of testing, you could reliably compare different vehicles as to output. Heck, go so far as to say different vehicles on different Dynos (say a Clayton in Detroit, and one in SoCal.) The standard testing protocols are what gives you at least a standardised number set for comparison. Without it...yeah, they're just numbers!

BLOZ UP Posted October 18, 2013 Share Posted October 18, 2013 But I thought turbo cars should not be correcting air density, look at SAE 1349: 5.5.2: On any engine where the power output is automatically controlled to compensate for changes in one or moreof the listed inlet air and fuel supply test conditions, no correction for that test parameter shall be made. For example, boosted engines with absolute pressure controls shall not be corrected for ambient barometric pressure. Quote Link to comment Share on other sites More sharing options...
blue72 Posted October 18, 2013 Share Posted October 18, 2013 Does anyone (monzter included) know if there's a way to find all these pictures still? Every time I click on one of his pictures in this thread I get an "invalid IPB path" error. I found out you can right click and select "Copy Image URL" then just paste that in a new browser tab. That seems to work well. I was just looking at some of Monzter's other threads a week or two ago and figured this out. Quote Link to comment Share on other sites More sharing options...

Yes, the only dyno sheets I really take notice of are those that show detail like the DynoDynamics ones do. A video of the actual car on the dyno with a real time view of the screen is even better. Not everyone is out to bend figures but in my opinion if figures are going to be claimed then respect the target viewer and do it properly.

BLOZ UP Posted November 14, 2013 Share Posted November 14, 2013 Nonstarter of a question. What's the question here? The SAE specs say to not use correction factors on force-induction vehicles: "Boosted engines with absolute pressure controls should not be corrected for ambient pressure" Quote Link to comment Share on other sites More sharing options...
Tony D Posted November 16, 2013 Share Posted November 16, 2013 And AGAIN, how is this in any way applicable to this discussion of NORMALLY ASPIRATED L-Series engines? What is the tie-in I'm missing to validate the inclusion in this comment into the discussion other than that of a Tourette's-Style outburst?
