all right and there it is we got the gdp intake manifold with the gdp grid heater
and the air boss plate and you see everything's nice and clean in there
cleanliness is key when going back together with a diesel uh if you notice there's a different
bolt there they do include one long bolt but you will need to use one from your old stock manifold
can't find it so it's a m8 by 1.25 by 120 millimeters that is the length of the intake
bolt for long bolts uh this works fine just went to the hardware store and picked it up
as you can see the grid heater connects right down there and a couple side notes on these
little injector crossover tubes right there those are torqued to 37 foot pounds every one of those
were loose when we checked them after removing the lines so it is always a good idea to check those
torque everything down um we did start it last night just to check for leaks there was no leaks
and we did notice that the idle actually improved now whether or not as because we cleaned
everything the lines you know had a little bit of rust on the end of them maybe there was water
in the system at one time we don't know but you want to make sure everything's torqued down and
just idle it till it's warm and make sure you have no leaks but we're going to go ahead and start it
up and see what the egts are and everything while we're running now normally after running the truck
when we come to a stop the egts would be around 325 anywhere from like 310 to 325 while idling
and then under normal driving between eight you know 750 to 900 i would say is the average range
so we'll start it up and see what we got all right we're in the truck
you see the grid heater turns on like normal no check engine light
and don't mind the fuel economy it should go up we do idle this truck
on startup and shut down to make sure everything is good so we'll fire it up
starts right up we have noticed an increase in about 100 rpm on the rpm gauge and it is
a lot more steady before it used to bounce between like five and 650 now it's steady
at 700 right where it's supposed to be so we'll go out and let's see
again everything's running smooth no issues don't hear no leaks that was a cold start
this morning it's about 80 degrees out so we're gonna let this truck warm up and then
we'll head out and see what the egts are okay as you see we got quarter million miles there
we are warmed up on street level tune and you see the egts are about 50 degrees
cooler so we're gonna get on the road and see what this thing does all right we are warmed up
here and we're gonna look over at the egts and this is just going to be part throttle cruising
and the egts are way lower than they've normally been
i mean we're talking egts used to be seven eight nine hundred it's definitely taken off quite a bit
again this is under part throttle under full throttle
you know we've seen over 1200 on the egt's and it's 73 degrees out so it's not too too warm out
but we're going to record all throughout today and just note everything so we can get it in the video
but cruising egts is right around 500 and we're doing about 45.
so it's doing really well
we're up to 50 now
never were the egt's this low while cruising i mean the lowest that we've
seen cruising was probably 650 700 so this is well over 100 degrees
off of the normal egt's and they see how they're dropping down we're doing 55 now
so we'll get around to do a full throttle pack all right we're going to do a full throttle
stomp on this thing and see exactly where the egt's are going to be like i said under
full throttle we were well over 1200 sometimes into 13 1400 and the fuel limiter would kick on
so it's about 80 degrees now 79 outside so we're gonna go ahead and hit it real quick
slow down a little bit and here we go
that's full throttle to 70 and we didn't even break a thousand so egt's are definitely down
a few hundred i mean absolutely amazing no no regrets with putting this on at all throttle
response is crisp no hesitation anymore in the idling the rpms have smoothed out and like i said
maybe it's because we cleaned out all the injector lines there was some debris in them and stuff
like that and we made sure that we vacuumed everything out but this that was with the ac
on and everything and you see how low the egt stayed under a thousand and that was full stomp
so yeah we're gonna monitor it all day and keep adding video in all right we are parked back from
that run and like i said the truck usually ran at about 320 between 300 and 325 on the pyro
when letting it cool down the idle down so we'll see if it gets lower than 300
it's always good to let your turbo charger spool down and kind of let the oil cool it off so it
doesn't cake up or i believe it's called coking the oil where it burns the bearings in there if
you want your turbocharger to last any bit of time that's probably what you should do
all right so we're getting down to that idle down range at 325 see if it'll go any lower
and as you see the peak we seen was 935 on the pyro and that was full stomp
all right we're dipping down that 300 area if we get under 300 then we know it's doing good
just wants to hover around there
but all in all it is doing well oh there it goes we'll see if it breaks into the high 200s
there it is as you can see the average and the max
so it's never idled this cool before it always hovered around 300 to 325 so
we're dipping into the high 200s see if we can get it to stay out of 300.
so yeah it's definitely running cooler at idle as you can see
we're dipping into the 290 280 area so staying away from 300 definitely cooler it's running
definitely cooler under max throttle like we said we've seen 12 to 1300 on the egt's full stomp
so overall this has definitely definitely helped the engine and like i said we'll come
back throughout the day and check out our average and peaks throughout driving and our mpg see if
it goes up from 12.6 which i assume it will all right we drove for a little bit and as you can see
it is 90 degrees out there it's pretty hot we've been idling a while we were at 13 average like i
said this is the lyo meter so i don't believe it until we reset it after everything but as you can
see sitting here in 90 degree idling we're at 270 260 which is great and we only had a peak of about
that dirt off there for you of 7.92 normally we'd be up in the 900 range so
definitely decrease the egts and we'll keep looking at it as we drive
the transmission shifts smoother everything the truck just overall feels good all right
we got the cruise control set we are at 70 miles an hour on the highway and as you can see here
we're going up a hill now but the egt's are in the they're in the mid 600s and like i said we're
going uphill now so once we level out you'll see the egts go back down normally we'd be around 900
to 1000 right now because it is 95 degrees out if you can see that 95 degrees out there it is hot
so there we are shooting back down into the 500 range so yeah this thing is definitely phenomenal
as far as keeping egts down we've never run this this low of egt's at this speed on the highway
all right so we just fueled up and we're getting about 18 miles to the gallon now
and that'll level off it's 91 degrees out still very hot and as you can see we had a max on this
run of 721 and we're dipping below the 300 mark again so overall yes this setup here has lowered
the egt's the boost feels better the truck feels better everything just feels better about it
so definitely recommend doing a grid heater delete uh just depending on what state you're in or what
part of the world you're in if it gets a little cold like below freezing you might want to go
with the inline grid heater option or something else or keep your truck plugged in overnight in
in cold weather but overall this does help and make the truck breathe better
the proof is in the numbers right here and we hope this helps thanks for watching please subscribe
