NA Dyno 2000 Projection

[MikeMan]

I decided to have a look what could be done with all of the ideas floating around here on engine mods at the moment

This engine uses the following:
3TC 89mm Pistons (TBC waether this is an option)
5.7" Small Journal SBC Rods with offset ground crank to get 84.5mm Stroke.
Ported heads with Standard inlets and 30mm Exhaust valves.
12:1 CR
Kelford 207-B Cams
2500CFM ITB's (4AGE 20v TB's drop by about 10HP and 6-8lb ft)
Good exhaust.

Final result:
458BHP@7500
399LB FT@5000

Just thought some people might be intrested in what can be done NA as most stuff on here seems to be focused to FI engines.

Nice work Mike..... 458 bhp... WOW...... How much do think it would take to make this happen?

Price wise is not going to be cheap.

SBC Rods
Forged Pistons
Head Work
Offset Grind the crank
ITB's
Cams
Standalone ECU (although a good mate of mine remaps nissan ECU's so I am looking at using a VH41DE Computer with a custom program, I will keep the guys in the loop with this)
Exhaust
Fuel system

But the sound and performance should be GOOD

That's pretty cool, is that a 4.2l ?
What would happen if the mufflers were deleted? Heh heh

Grind the crank down even more and we can use a longer Lentz rod (all over ebay for $200) with more stroke and a better rod-to-stroke ratio. They also have ultra-lites going for $700 a set, BRAND NEW.

Do you have any of the files you used for this? Like the Kelford cam file?

Yeah it is 4205cc

With the Dyno 2000 "Large-tube headers Open Exhaust" option the engine jumps to 490HP @ 8000 and 408lb ft @ 5000-5500

Yeah 84.5mm is probably enough though.

I have attached a .zip with all of the .cam and .flw files that I have for the 1UZ-FE.

Mike,

Can you convert your 1UZ-FE.zip data into pdf?

 

[MikeMan]

I do not know if it is human readable.

I will check.

Mike, what other options for fuels are available in Dyno2000?

Also, does it allow you to predict at what dynamic compression you'll have knock, depending on octane, boost, ignition advance, etc.?

If this program won't/can't, are you aware of any other desktop dyno's that can?

TIA,

John

It does not do dymanic compression.

Dyno 2003 Pro MAY do it but I do not have the $600USD to find out

The Dyno2000 that I have does
Gasoline
Gasoline + NO2
Methanol
Alcohol
Propane
LNG

They are config files for Dyno2000 and they are not human readable.

The output I do via a .PDF printer (PDF995) that is free for non-commerical use.

Thanks! Time to start playing...

It actually will do dynamic compression, look in the tables for the dyno runs and you'll see BMEP as a number, it shouldn't go above 200psi or so.

thanks for the .cam and .flw files btw

Yes it does, but it assumes that Gasoline is detonation free.

So you can make an educated guess but that is all.
