The intercooler makes the charge denser

@@shadowopsairman1583 Yes, which increases power, since you have more oxygen in the same volume, which you can combine with more fuel to make more power. But I'd be installing an intercooler mainly for the extra longevity and safety. 🙂

@@Roddy_Zeh or the same amount of safety with more power 🤔

Agreed but E85 doesn't seem to care. Pump gas needs an IC. Only 14 hp gain with the IC and all that decreased temp. Probably because that small IC core is restrictive to flow.

@@Toys4Life You may be correct- and anytime an effective IC can be used, I'd use it as a hedge against detonation, as it does do a good job of cooling the charge. I've read that too big an IC may cause a little bit more lag, but IMO, more is better than too small of an IC. If all else fails and E85 isn't a viable option, spray meth or a meth/h2o mixture. The methanal effectively raises the octane, while the misted water handles the charge cooling duties AND keeps the carbon to a minimum(and will clean a dirty combustion chamber). I've never seen anyone use E85 AND spray meth/alcohol at the same time tho, as I'd assume it's due to diminishing returns, although I'm not 100% certain about that. E85 is not convenient for all of us, but spraying meth is an easy, and likely less expensive alternative, regarding the setup of both.

It would, making such a test on e85 removes half of the effect of the intercooler, since it could run close to mbt igntion even without IC.

The gains would be even more pronounced. On 3800s be usually either do intercooler or e85. Not usually both. And end up around the same numbers with a cam.

Very well said

I recently started watching him and I CANNOT believe Richard's work ethic and obvious love for what he does- we are fortunate to have his knowledge as well as the rather extensive library he's created along the way! IDK where else you could find that- and he doesn't seem to mind answering my most basic of questions... or telling a person if something will not work either. Straight up guy for sure!

@@btchhopperou812 pretty crazy huh this guys the beezzzzkneezzz this information is detrimental to my next build

Extrude hone does some cool stuff. Porting the unportable!

nope

If you're having this issue and fans make it better you're not getting any passive flow of air through the heat exchanger. The air flow offered by a cars movement at say 100kmh or 60mph is magnitudes greater than any airflow fans can provide. A common mistake people make when installing aftermarket exchangers is assuming they work with positive pressure. This in fact wrong and no amount of air ramming will fix the issue. You need a pressure differential across the core so you need the egine bay to create negative pressure. If you examine OE cars you will find there is plastic all around the radiator to separate the engine bay from the front side of the car. This creates a high pressure zone on the front side and a negative pressure zone on the back side of the radiator allowing air to flow. I would imagine your intercoolers radiator is getting postive pressure behind it and you've bainaid fixed the issue with fans.

It shouldn't, on the supercharged 3800 the injectors are mounted on the intake port on the cylinder head, pretty far downstream from the blower.

i think ethanol helps with Combustion temps, not so much IATs. The injector isnt far enough up stream to effectively cool the charge

L67's are fine until you start breaking stuff. Parts can be a bit pricier and harder to come by. I loved my L67, but the LS platform is just so much better supported.

@@GreaseMonkeyGarageTX I've seen a few higher HP 67s but never seen any issues. I've seen more problems on daily driven 67s that were neglected

@@Matp345 once you start pushing them they break. Rings touch and you chip a piston. Forged pistons have a thicker ring grooze that helps a lot, but you are limited to a few options. The ARP kits were hard to come by, not sure if they still make them. Heads lift, head gaskets blow out, etc. I races an L67 for years and it was a blast, but not cheap or easy.

SHOT ON MY PHONE, DONT HAVE A SEPERATE WATE RPUMP, JUST THE DYNO-WE REGULATE THE FLOW WITH A VALVE, WATER IN WAS 68 DEGREES

gained 100 hp?

@Richard Holdener yes,on the dyno 1st no water in intercooler then water minutes later and was the result.

I think it dropped under the IC core due to the restrictive IC core. I think boost went UP above the IC core.

As far as intercoolers go. That's why I'm here. Considering using one for the 4.3 in the 75 Celica ST. And yes they are on clutches also. (2) I love the fabricate.lol But the extra horses from the intercooler would be welcome when playing hard.

What would happen then if you just ran methonal and didn't mix it with water?

@@177SCmaro - You would make more power. One problem with running straight methanol is that it is a hazardous material. That why Boost Juice or anything like it contains up to 49% methanol. Shipping hazardous material is expensive. Methanol fires can be dangerous because the flame is practically invisible and it has a very low flashpoint. It's safer and more practical to mix methanol with water.

Not true about the water as it's expansion rate increases compression ratio, if you think otherwise the go tell David Vizard he's wrong also !

it was the dyno-its fixed

IT'S THE DYNO-WE FIGURED IT OUT

THE AC IS IN THE BELT LOOP, WE DON'T RUN A THERMOSTAT (THIS IS NOT A STREET CAR-IT'S DYNO), WE RAN DOWN TO A 2.6 PULLEY, i WOULD BE SURPRISED IF WE COULD MEASURE AND DIFFERENCE WITH A PHENOLIC SPACER-MAYBE IN A HEAT ENGINE BAY

My dream setup was always to ditch the Gen V and go with a whipple.

I'd love a tvs rotor pack for genvm90 or some twin screw

WE USED A HOLLEY HP

I have a 3.0/intercooler/e85/stock cam and i make around the same boost. 11.5-12

@@sg34qw you always lose boost running through an intercooler and even more adding a cam. I'm interested in seeing a stock cam car intercooled to see if it runs more boost than the cam intercooled with same pulley size

i have this same setup Richard ran but with a stock cam.. i run 11.5-12lbs of boost. maybe my teflon coating is worn, but its the same boost as richard was running.

@@sg34qw I ran 14 pounds on a 3.1 pulley, non intercooled. I would just like to see a stock cam intercooled pulling down as low as you can go without kr.

@@CBbailey im just saying you said you'd like to see what boost a stock cam would make on a intercooled 3.0 car. And im telling you what mine makes. If you made 14lbs with a 3.1 you had an exhaust restriction.

Yellaterra for w2a

e85 is knock resistant at higher temps. if it was "almost an intercooler" you wouldnt see 214 degree IAT's non-intercooled.

@@sg34qw eh.. the reality lies somewhere in the middle. The temp probe is before the E85 is introduced. E85 DOES significantly cool the air, but not until it's going through the port and into the cylinder, where we can't exactly measure it with a temp probe. But, you can calculate it.

@@armcclure e85 barely makes a difference when you have multi port injection. It makes a significant difference when carbureted or tbi.

Single turbo with e85 blowthrough carb no IC. 25psi boost airtemp before carb is 210-220F. And below the carb 75-80

@@triplestangman it makes a bigger MEASURABLE difference with TBI or carb. I understand what you're talking about, I've seen high-rise blow-through E85 turbo cars with condensation on the outside of the runners. That cooling effect still happens in a port injection setup. The fuel still has to change state to burn. We just don't have a temp probe inside of the combustion chamber.

BINGO

colder is better but you still have losses from driving the compressor

Water displaces air and fuel decreasing effective displacement as well as

COMPARED TO THE WATER METH

Good question, I was wondering the same??

we use a simple digital type k

Anecdote ahead: I had a similar setup (build shortblock with 9.5:1 pistons and an overdrive crank pulley)and while I could run a 2.8", it ran best on a 3". But I guess thats closer to a 2.6 with a stock crank pulley so i guess this whole reply is moot! Lol.

WE KNOW ADDING BOOST ADDS POWER

steam does have much higher volume than water, so that should help drive the piston down. At least that is what the F1 people said when they played with water injection

YOU DO USUALLY HAVE TO ADJUST JETTING FOR BOOST-BUT THERE IS ALSO A BIG CHANGE IN SIGNAL WITH BOOST (WHICH DETERMINE FUEL FLOW)

YES

@@richardholdener1727 I was amazed at how much is cooled the charge. Also would have thought that would have resulted in a lot more HP which tells me it must have been several PSI drop in boost due to the restriction of that small intercooler core. My conclusion would be that the IC is worth it with pump gas, maybe not worth it with E85. Curious what others think?

@@Toys4Life … I was also impressed by the significant and consistent drop in temperature when using the I/C components. The psi loss across the core is minimal in most cases and shouldn’t have caused a very serious loss in power output. I also noticed how many people make a distinction between pump fuel and E85. I haven’t traveled out of the Atlanta area very much over the past couple of years so I can’t really comment on the availability of E85 in other parts of the country but locally it’s available at nearly every refueling station on every corner. Since 93 octane “pump fuel” and E85 come from the same pump, it will all be called pump fuel eventually 😁. Or so it would seem.

I remember racing whipple swapped Terminators that barely got warm. Those heatons are exactly that.

IN MANIFOLD CORE TO EXT CORE MAN?

THE AIR TEMP WAS POSITIONED UNDER THE BLOWER IN THE LOWER MANIFOLD

I DIDN'T LOG IT UNFORTUNATELY, BUT IT SEEMED (VISUALLY ON THE GAUGE) TO DROP SLIGHTLY
