…… which accounts for about 98% of LS engine applications.

My thought is Not trying to fuel the engine just cool the incoming air with a 100% Meth mist. Mike said it maybe worth 3% in theory. Story of Bo Butner and how PS et times were slower than a carb and what was done to help et's to reach what's run now.

Smokey B

BTW KCS, Mike said what you said is what's wanted a cold intake that cools the in coming air. Fuel or mist on the runners or plenum does what? Cool the intake which would cool the air.

You mention the story, but what about it? Expand IF you're able to....

Mike didn't go into details. I called a few people with the idea of using the new holley ram nos plate system for a cooling effect. All said it was a good idea may not get some major hp. I just take information and try to put it into practice if possible.

Injector placement moved Up and spray patterns have changed since PS started using EFI from the 1st season till now.

Smokey B

If you want to really know or ask about a PS engine or anything along those lines, Nick Ferri is on YB a good guy and will answer a question.

2 injector system, with 1 injector low for idle & normal driving the other injector near or at the TB face / opening aka F1 racing ^rpm. That thread with Darin i posted? 1 of My Favorite, if not my Fav. persons in the whole wide world gave Class. When he talks i Listen! Besides texts with Q&A's

You are, what you learn and observe, choice is from who do you get the information?
would a person rather detune for a app. Or try to build for a app?


If you believe in the air pump Theory for a 4 stroke engine..you have the 1st step to do things only dreamed of 20 yrs ago, with basic Common stuff now.

I have a meth kit to install for the cooling effect mentioned. Got to be worth something, especially in summer months

Smart, it helps keeps temps down = more hp.
U: Out think a problem, not the other way around. Most have theories but never ask. Not me.
Goal of a street engine on e85 with less than 420 ci 850hp wanted? with junk for a block. talked with all the key players involved and some need a tweak. 8000 isn't a lot of rpm. Ford sells a regular car that goes there stock. Gearing?

Better idle, with street manners and different fuel. But Perfect.

More compression.That's all. Love those cheap FACTORY ls3 heads.
https://ls1tech.com/forums/parts-cla...s-lifters.html
Less rpm more compression.

The Ls3 combo cam is way smaller... do have the specs. loolz. 1 common theme and it's about air pumping?

I want a nuclear bomb going off in the cylinders = higher compression, with more Air and fuel taken in. rpm peak can be controlled. They sell great springs (pac/psi) and a 800 lift cam can calm down.You could use less lift 650 to 750. (Holding a valve open more / higher lifts adds more fuel and air. We can hold it open longer only so long, we've got 3 other cycles besides intake.) i asked Darin why use a cam with more lift than the heads flowed and peak was .700ish but a 815 lift cam was referred?

Thought is utter disrepect for the next guy & there combo. Period and call it street.

800+ also. Et's were run in Denver, Colo.

Smokey B

Funny what if e85 were available for the 434ci Ls7 830hp combo and the compression went up. Hmmmmmmmmm...numbers sound about right for a compression increase & we keep the same 7500 rpm. Get in there, damn air & fuel....

I just built a nice 427 street motor that makes 657@7600/575@5200 on pump gas. 671/575 on race gas

The 4.10 gear and 4800 ptc converter will work well and make for a fun street cruiser

Smokey B

It's all about aspect, expectations and knowledge when dealing with a AIR PUMP. Efficiency = compression and free hp. Nothing beats free. If you get more air & fuel in.....hp will come. Field of HP" written by...lmao!

Smokey B

Normally a PM to _______. Read the thread yesterday, and said what the hell lets pen point everthing, so i went to wallace calculator. All i can say is Damn Darin!
https://www.yellowbullet.com/forum/s....php?t=2571027

CSA matched exactly what the calculator said was needed 2.99 inches for 8k and my CI. •Ls7 typical port centerline is around 5.6 inches (https://www.yellowbullet.com/forum/s....php?t=2569811). Got a 275 cc head.
http://www.wallaceracing.com/csa-calc.php

Flow wanted by the cylinders @ 8k with the the same CI came in around 371 cfm (we've got about 8 extra) Using the 115% VE read about.
http://www.wallaceracing.com/calc-cfm-head.php
360cfm min. needed at 8k (1 cfm away from being 20 over what's needed.)
http://www.wallaceracing.com/flow-rpm.php

Port velocity is around 380 @ 8k.

Engine Power showed how to test and show when you run out of intake for a application using and measuring air taken in at the face of the induction system & manifold vacuum on the dyno. Example.

If your tb / carb, flows 1750 and 1300 cfm is read as being taken in with 1.7 inches of manifold vac. on a engine dyno...intake is the bottle neck

It was discussed and the math came out to ~900HP but I'd have to give up the 5.3 block for a Dart LS Next deal. At some point the madness has to end and for me it is budget and down time.

Smokey B

Cylinders won't stay round due to aluminum factory castings even with dry sleeves. Just a thought and ref. what if dome pistons were chosen from the start (more cylinder pressure), with e85 in mind that's all. Same motor.... Hell that thing is all ready sucking air and is great @ moving air in & out.

I understand..... luv the dart's bore capabilities vs a resleeve. same 5.3 in mind.

Was watching nhra pro stock qualifying.... Chris Mcgaha car caught fire. Later they showed the engine, holley style intake short runner like 2 inches max. Injector is you can't see it............ You see the rail but No injector Bung for a or any injector. And this was a close recording, like 2 feet away. If that's the injector where the wires are running (by the rail) x4 ???? Then it's location is @ the top of the runner where the holley base has it's mounting points for the 102 TB top. Very top of the base. Looks like a 125mm TB or larger

Totally agree.
For a 440 engine the LS7 is the way to go.
The torque will still be plentiful in the low and mid range and kill the cathedrals in torque and power from 5500rpm+
Plus the price difference.
What I have realised is, that since the ls7 heads came out GM have not made a different port design that flows better.
I think we have reached the pinnacle of flow for the head cylinders.
I would love to see someone design a different port shape that smashes every other product out there.

Smokey B

Other valve layout arrangements?
You can get a blank piece of aluminum and have 1 made....

I've talked it over and getting a as cast mast or all pro head and creating your own is not out of reach. Oval port? Valve angle? Your choice.
We like the idea of making a program of what i have now and placing it on a better head or rasised runner. $700 to digitlize a port program $1000 for cnc
Buy your castings. Around 4000+ with valves = mast srt8 / mozez / lsx-r heads and a smaller runner. Or just epoxy the runner to the desired volume or csa.
Custom heads cost custom $$$$.oo

Do you talk to every professional in the business? Its what I gather from all your post. Just wondering
