Sorry 50%, stupid not being able to edit posts lol

As for actual testing I'll have to wait till spring time now as anything more than 5% throttle in gears 1 through 4 at any speed just blows the tires off lol

Ya I'm not 100% clear on that 15% thing in the sae j1349 standard but it's supposed to be corrected to a specific barometric, density, temperature set if variable and is supposed to be what all new vehicles etc are tested to. The uncorrected numbers are 523whp/547ft-lbs which is pretty close...

whats your ignition advance at say 160/180/200kpa and 4,000/5500/7000rpm? I'm actually serious about trying to figure out whats going on cause in my head I think the dyno is wrong but at the same time I dyno'd with the automatic trans and 8psi with a max of 424hp/450ft-lbs dyno is a dynocom...

Thanks justen, exactly the kind of replies I'm looking for. I'm constantly explaining to less-knowledgeable people who always immediately ask what psi I'm running as if it's going to tell them exactly how much HP I'm running. Bigger turbo at same psi as smaller one will make more HP as it's...

Serious question, how am I making [email protected] Relevant build information: -7mgte 440cc injectors -Precision Turbo Billet 6262 ball bearing, 0.58AR t4/v-band -megasquirt AF/r is 11.4-11.8, timing is 22deg at 4krpm tapering to 20deg@7k -Totally stock early crown majesta engine -semi-log...

^correct to SAE J1349 here is uncorrected at 3000ft elevation

Incorrect should say uncorrected

Math was incorrect apparently lol, stock intake manifold still 573whp/599.5ftlbs@12psi on 94 octane pump gas, sea level corrected btw, incorrect at 2900ft elevation was 524/549

i've had the threaded portion stay behind and removed the rest of the sparkplug come out, tip to electrode steve

Intake Mani hasn't been done yyet, that was a dead stock motor but running 12psi. Original dyno was done at 8psi. Doing the math for 8psi vs 12psi, 1/4 mile MPH and weight it should be making in the neighborhood of 450whp@12psi uncorrected or 485-490corrected to sealevel numbers with intake...

Good to know, oddly enough have never heard that vertical cores cool better? Always assumed it was a packaging decision, ie great for front facing intake manifolds in a twin turbo configuration with a dual inlet lower and single outlet upper

huh? steve

Dead stock 91 ls400 engine, w58, custom 4-1 shorty headers and a cone filter:247whp and 270ft/lbs

too be honest, in my 3 1uzfe powered cars including my single turbo'd 92 motor making 500+whp I run Shell Rotella T 15w40 in the summer, its got a lot of detergents for cleaning up high mileage engines as well as all the additives that they need

Went Drag racing again today best run of the day [email protected] with a 1.93 60foot. hankook street tires, no cage lol theres a 10.60 in it pretty easy with some sticky tires

cannot use spark cut but still can use fuel cut steve

And sorry I didn't mean for it to sound like I was pushing mine on you, just clarifying that the megasquirt can be configured to control the factory dual dizzy/dual vr sensor configuration
