K20C1 HAS BENT RODS @ 400 + Hp - POOR TUNE or Poor Fuel . . or Both ..
that said I'm sure there are Plenty of R Motors that will Go to 600 Plus HP .. If Tuned Properly ..

Still Doesn't Mean an Accord with slightly Lower Spec's , but has 10.8: 1 Compression is Great
Candidate to Go Slapping on R Turbo and then Stage 3 ( Working Compression is Super High )

Not to Mention Fuel - really need Larger Injectors - Larger Fuel Lines & Pump .. or set of Secondary
Injectors & Supply with Proper Timing to Kick in say over 20 Psi & 5000 Rpm's approx ..
all way to 7100 Rpm ( Unless Your have Special Head Work ) then able to do 8500 Rpm ..29_30 Psi
Boost ..

Tweaked Turbo's with way Better Hot Exhaust Gas Exit Flow - would be Step in Right Direction ..

Added Ported High Flow Oil Pump & Oil Pan with Better Control ..for High G's is also Needed..

High Flow Cat Down Pipe - Plus anyone Heading for 500Hp should be looking @ Special Pistons & Rods with Great Coatings

( I'm Not sure what " Your Oil Pumping Loose " is with 10W-30 Oil . . ? ) But Oil Squirters have Very Small Orifices ./.

10% Increase in Oil Flow Go a long way to Aid Piston Cooling . . which Reduces Knock ..

Cooler Pistons - have Less Ring Load under all Extra Higher Stress - which is Beyond
Original Design Extra Boost & Bigger Turbo's = so Cooler Pistons = Less Friction . .

Less Friction means Motor Gains HP ,( Spins Up Faster ) but More Important Less Drag means
those Micro-Sec's of Down Ward Piston Travel = Equal to Less Blow By ..( Everything is Operating )
Inside Original Design Envelope ./. or as We say Porting Land ~ Go ~ with the Flow . .

Ported Oil Pump is Good for 2-3HP & 2.5Tq all Ready Proven . .

Beyond dumb post from someone who thinks compression ratio means anything when the K20 is one of the most over built, over oiled, and over engineered 4 cylinders since the B series.
500hp out of a K20c1 on bolt ons is now "normal".

Hey from One that Always " Whining " about " Oil Dilutions " & Knock Counts - LO Haa - Your Just a Parts ADDER and Hope for Best .. Haaa

Compressions up above are looking at Working Compressions which are in the 19:1 ~ 22:1 with Higher Boost - Darn Like a Diesel Motor with Not Proper Fueling ..
Amount or Octane .. ( All You do is Trying to Hit Below Belt ) Haaa

I'll Port Your Oil Pump for Ya . . 4 Free as a Test , but Shipping will be $396 . .

OK , Yes I'm Worst Speller . .

Here are some Cooler Pistons : Pictures - Note Coating & Piston Oil Cooling - being Drained out Drilled Holes @ Oil Control Rings

First Up is Working Compression - where it will Show to All what Fuel You should be Running @ what Boost . .

Has Anyone Contacted this Guy - sure Seems - Been in Scene ~ Awhile ~

OK Something New !

 

[EngTech1]

Yes Honda's Engineering is Very Good .. Why I made Switch . .

Always Loved Yamaha's & Their Engines .. also Really Built Very Well ..


Really Seems like this Ethanol Wave were in is Really Maturing - Not sure what Percentage _ Items all around Fuel system are Rated for - I would believe 15%
seeing many States are Moving to 15% ..

Electrical Boosted Turbo's are starting to Be Real Item Mercedes just Placed one into Drive_Lines & BorgWarner has had many for while Now ..

Just Tuning to Side of Safe . . ( Heck If I was working & Not Retired ) Pulling Dow Number in My Field that they Pull Down Today ..

I'd Just Buy Entire R Motor Full Assembly seeing that have Items even for that Now .. ( Drop that In ) . .

Looking In Side K20C1 Turbo Tongue is Designed for More Mid Range & Vane Slit to Send Pressurized Compressed Air on it way Leaning more Towards Efficiency with More Flow
High Exit Speed . .

1 of White Pages out of 9 or so I have reviewed & Studied over Last 15yrs to do with Turbo's ~ & ~ shows some Experimental Testing of Scroll Designs .
ie ( Sizing Results )


Will Also show anyone some Terms - may have Not Known . .


Here are Few Pictures of Type R Turbo . .
Many have already seen Unboxing of New Turbo ..

Now I'll show some Work :

Little Pumping Up Wastegates Ability to Flow .. this Deeper inside around Scroll some ..

Turbo's Exhaust Entrance being Blue Printed - Flowed

Casting is Fairly Rough - roughness Scale approx RMS of 35

Currently RMS is @ 180 with some Polishing Moving to 240 ~ 320
. .

Lead In Heading Up into Gate now has a Large Radius .. D Shape ..

Looking at Turning Up Boost on smaller Turbo's like Stock IHI Accord Turbo - Reasons Your seeing Heat ..

First Up - Compressor Wheel inducer Tips are Running @ 660 Mph stock - Turned Up in 3 Psi Mode Tip Speed moves to Super Sonic - Over 740 Mph ..

Larger Vane Tips @ Bottom Pushing all Compressed Air are Now Going from 700 Mph to 790 Mph or more Depending on Final Rpm's . .Well Over Super Sonic Speeds Creating much Heat ..

If you divide the amount of power that goes into building pressure by the total power put into the compressor, you get the efficiency of the compressor.

For example, if Compressor is in 74% efficient Range , this means that 74% of power put into Compressor is used in building air pressure. The other 26% of Power is used
Heating up the Air. That is why we like high efficiency compressors - Porting Turbo make it more Efficient . .
Examples :
A Calculation Example :

Tout = Tin + Tin x [-1+(Pout/Pin)0.263]
efficiency

Example: Inlet temperature is 70 deg F, the suction pressure is -0.5 psig (a slight vacuum), the discharge pressure is 19 psig, and the efficiency is 72%. What is the discharge temperature?

Tin= 70 deg F + 460 = 530 deg R
Pin= -0.5 psig + 14.7 = 14.2 psia
Pout= 19 psig + 14.7 = 33.7 psia
Pout/Pin = 33.7/14.2 = 2.373 (this is the compression ratio)

Tout = 530 + 530 x (-1+2.3730.263 ) = 717.8 deg R - 460 = 257.8 deg F
0.72

So the theoretical outlet temperature is 257.8 deg F.
I sure would like to have an Inter~Cooler to Cool that Hot Air down before it goes into Your Engine !

Many of You are Running Temps this High . . so Data from Logging Intake Temps - would be Nice . .

 

[EngTech1]

First I Stated It's an Example : PERIOD !

" You Especially " may have to Read Items 2-3 Times to Understand It ..

Point is One should Try to Keep their Tune or Turbo Out of Super Sonic Choke Area . .

Haa. I'm already Proven in Many Area's some of Which You haven't even Heard Of ~ Pal ~ Haaa !


I'm Simply Placing Up Knowledge so Others May - Investigate what I've Known ..& Come to Know in Last 15yrs
On Turbo's . .with 30 yrs Porting backing that Up ..

You don't have a Lick of Informational Guidance then what You've read from Your Tuning Book & Gathered from Other Forums .. that Nice - but It's Not Science - It's NOT Investigated Knowledge that takes Years of Experience to Gather .
and Develop - Go Ahead give this a Full Reading - You will have to Read it .
2-3 Times to Fully Grasp everything ..

If You Don't Have Experience or Back Ground to Go with It - Then You May Never Fully Understand what Others Investigation have been doing - Further These Testers with Special Test Equipment - Even State They Have Area's
that are ~ Still Unknown ~ this is Bleeding Edge in many Area's ./.

Another White Paper of - Now 14 - White Papers _ I have Investigated to Deepen My Personal Knowledge

NO Pictures are all Mind - which also came From My Other Forum Post . .

YES I POSTED SOME EXAMPLES OF HEAT FROM GOING SUPER SONIC - ON EDGE OF CHOKE POINT..

We are Going to Ignore YOU !

GOT IT !

Been Talking on Several sites for 25 yrs - I don't Need Abuse Nor do I Abuse anyone .. Nor do I Lie !

 

[EngTech1]

START READING - LET ME KNOW - 1/3 WAY THROUGH PAPERS I GONE THROUGH IN LAST 15YRS ..
IT WILL ONLY TAKE YOU 2 YEARS - IF U START NOW !

 

[EngTech1]

Now I'm able to Go back 10 yrs and Find all Heat Transfer studied I've done on Turbo Exit Pipes ..
with Complete Heat Transfer Analysis for those Exit Pipes & Manufactured them ..

sold 5 Units as Price was High for Stainless steel 2.25" Materials all Designed & Welded ..
Leading with Examples of How Hoses ate to Properly Fit those Pipes for Smoother Air Flow - of Which . .
Others Copied !

Do I really have to Go Back & Pull Out My History - LOL HAA - it's all Over on SS Forum . .

Turbo Exit size was only 1.4" Dia. so Tuning it was getting Items really Hot !

( WHY ) well , just try to imagine 15yrs back ..

Heat was Huge Issue & Still Is Big Issue . .

 

[EngTech1]

I'll be Placing More Picture of R FK8 Turbo as I have Time .. in Meanwhile , Start Thinking about Controlling Heat !

 

[EngTech1]

For example, if Compressor is in 74% efficient Range , this means that 74% of power put into Compressor is used in building air pressure. The other 26% of Power is used

ARE YOU TURBO WHEELS RUNNING SUPER SONIC ? ( MAYBE YOU SHOULD CHECK IT OUT )


Another White Paper of - Now 14 - White Papers _ I have Investigated to Deepen My Personal Knowledge

This one is on Splinter Blades - Placement & Effects of Different Combo's of Blades & Blade Design ..
Those Impacts upon Diffuser

If You elect to Read entire Testing Information that was done for Heavy Industry - You Will Like Your Honda
Turbo much more ..


Testing of Turbo's Compressor Blades with Splitters

Opening of that Slit is Only .122 x 5.5" Long You do Math How much Heat are You making If it Goes Super Sonic . .

Difference Between 95K ~ 115K Verses say 126K ~ 135K when Turbo's Goes from 78% to 75% Eff%


I'm Sure You able to Find some Calculator's to Help You . .

Pictures Show a Light Slowing Going All Into Very Back of that Slit .. of an Opening .. Progressing from Left to Right as
Opening is just Under 50% of Full Dia. of Diffuser , Plus it's Not Centered on Volute

Doing some Ball Park Math just to Place It I got 3.56lbs Boost @ around 121K these are Rough Numbers .. As Ya have No Exact Figures on
Honda Motor Eff% & Turbo Eff% & Temperatures & Impacts from Intake systems - all could Pick Up Eff% Numbers . .
All FK8 Maps I found were Not Legible for RPM's ~ Ball Parking It 18.26 Psi . .
