Well harness for LS1 PCM is almost complete and will be sent next week I’m doin one more task before tune

 

im making a custom set of extractors, 1 7/8 inch for 10 inches then into 2 inch primary’s for 20-23 inches with 4 into 1 collectors into either the 4 inch that srink down to 3.5 in this picture or a set of slip on merge collectors

 

also using 3.5 inch cats and a set of 3.5 inch Moroso mufflers before it connects to my existing twin 3 inch system

 

I have also found a place that sells e85 not all that far from me so a flex sensor is on the cards

And also think I’m goin to need to use proper slip on merge collectors as I relay think each pipe will need to be installed individually then the collector slipped over them

 

will see how I go

Well these turned up today

 

progress ss will start this weekend but I really think it’s goin to be at least 3 weekends or more to make these

 

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Holly shit man, you paid $900 for them

 

where did you get them from to pay that much ??

 

Should have been more like $500 for 8 of them, $900 is injector dynamic or Bosch ID territory

This happens when you have a apple device logged on and try using another device like in my case a samsung phone

 

Or vice verca

^^^ that’s bloody awesome

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Yeah I also agree platinum’s are over kill for this

 

I would stick with the street terra you have, biggest question are they 5/16 or 7/16 studs as I would want 7/16

 

5/16 will probley still do fine,  I’m not sure what the recommendations are on this

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Yella terra platinums would be far supperia to crane gold series

 

I dont think crane golds come in adjustable

Also they are not shaft mouted like yella terra

 

Look up the specs of yours and if they are the adjustable ones and good for 400 lbs spring pressure they will do the job and next step from there is $1150 platinums

 

When i built my engine i had a set of crane golds with intentions of goin a hydrolic cam but was advised by pavtek to go shaft mounted so i returned them as i only got them a week earlier and then it all blow out and i went solid cam as well

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Yes exactly, 78 mm is slightly bigger then 3 inch so is good for 1200hp or so perfectly sized

Before it could get more efficiency from goin larger but will still work with more hp like you say others have pushed 1500hp

 

personally i I would stay at 78 mm as well with mathematic side of things

 

epic build design 

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

And throttle body falls under the same size system

I dont know what size a factory 3 bolt LS throttle body is though

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Throttle body size actually does matter, it actually matters a lot

This is something iv found on a another forum when looking at weather my 2.75 inch pipe would do for my v7 blower and the answer was no it wasn’t big enough

>0.4 Mach is the point at which air becomes turbulent and losses in efficiency start to occur exponentially. The key is to stay under that speed. You want to use the smallest piping possible that still flows enough to meet your needs. Larger than necessary piping increases lag time with no measurable gain

The velocities are in miles per hour and mach, and the flow rates are in cfm. Measurements for the piping are in inches.

2″ piping
1.57 x 2 = 3.14 sq in
300 cfm = 156 mph = 0.20 mach
400 cfm = 208 mph = 0.27 mach
500 cfm = 261 mph = 0.34 mach
585 cfm max = 304 mph = 0.40 mach

2.25″ piping
3.9740625 sq in = 1.98703125 x 2
300 cfm = 123 mph = 0.16 mach
400 cfm = 164 mph = 0.21 mach
500 cfm = 205 mph = 0.26 mach
600 cfm = 247 mph = 0.32 mach
700 cfm = 288 mph = 0.37 mach
740 cfm max = 304 mph = 0.40 mach

2.5″ piping
4.90625 sq in = 2.453125 x 2
300 cfm = 100 mph = 0.13 mach
400 cfm = 133 mph = 0.17 mach
500 cfm = 166 mph = 0.21 mach
600 cfm = 200 mph = 0.26 mach
700 cfm = 233 mph = 0.30 mach
800 cfm = 266 mph = 0.34 mach
900 cfm = 300 mph = 0.39 mach
913 cfm max = 304 mph = 0.40 mach

2.75″ piping
5.9365625 sq in = 2.96828125 x 2
300 cfm = 82 mph = 0.10 mach
400 cfm = 110 mph = 0.14 mach
500 cfm = 137 mph = 0.17 mach
600 cfm = 165 mph = 0.21 mach
700 cfm = 192 mph = 0.25 mach
800 cfm = 220 mph = 0.28 mach
900 cfm = 248 mph = 0.32 mach
1000 cfm = 275 mph = 0.36 mach
1100 cfm max = 303 mph = 0.40 mach

3.0″ piping
7.065 sq in = 3.5325 x 2
300 cfm = 69 mph = 0.09 mach
400 cfm = 92 mph = 0.12 mach
500 cfm = 115 mph = 0.15 mach
600 cfm = 138 mph = 0.18 mach
700 cfm = 162 mph = 0.21 mach
800 cfm = 185 mph = 0.24 mach
900 cfm = 208 mph = 0.27 mach
1000 cfm = 231 mph = 0.30 mach
1100 cfm = 254 cfm = 0.33 mach
1200 cfm = 277 mph = 0.36 mach
1300 cfm max= 301 mph = 0.39 mach

My v7 blower at 100% runs 1400cfm but I don’t have it at 100% so 3 inch was perfect for me and my pipe at full boost would be bust on the limit of nearly 300mph air speed

 

In order to convert from Lb/Min to CFM for the equation above, you take the flow rate in Lb/Min for your turbo (generally an educated guess based on the pressure ratio and power created) and multiply it by 14.27. That will yield the CFM flow for your setup.

For Example:
T3/T04e 57trim .63ar @ 21psi makes 452 whp
This turbo is known to have a 50lb/min compressor wheel which will make ~500bhp. Since we’re using whp above, we can assume this turbo is pretty close to its max of 50lb/min.

Now to convert that to CFM, you take 50lb/min x 14.27 = 713.5 CFM. When you refer to the table above, you can see that we’re starting to max 2.25″ piping, but we’re still in the “good” range for 2.5″

but it also depends on how smooth the piping is inside… and all the bends. this i would say is ” perfect piping conditions” and if you would pick a number to upsize your piping at it would be when you hit about the .3 maximum .35 mach region.

Just get the light bulb out of doom light and hold 2 wires onto it and turn fog lights on and touch the 2 wires onto the pins in that plug to see if it’s power for fog lights

 

I think you will find they are for fog lights

 

Just get some water prof plugs from super cheap and fit them on both harness end and fog lights and problem solved

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

How is that tacky ??

 

If your looking at the bits around out side Thats a protective plastic piece over it that you peal off ay

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

You got to slide them down wards and that gets the 2 other clips out doesn’t it ?

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Awesome stuff

 

please please get a  70+year old couple  behind the wheel and pull up beside a new hsv/fpv any thing with a 19 year old behind the wheel who thinks he is cool and have the oldies look over and say,  look at that piece of plastic would ya, and take of in a cloud of smoke

 

and post that vid on here

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Pretty  much  no

 

Have you got 5/16 or 7/16 rocker studs ??

 

Your talking up around 350-380lbs  open valve pressure (I think)

dont think a affordable rocker is in existence except poo comp might have some puss

 

an get yella terra street series 5/16 rockers  for like $640 ish and think that’s rated to 400lbs pressure and if you have 7/16 I’m not sure as platinum’s are about $42 thousand pesos if you happen to be in the Philippines or shit loads in oz

 

maybe if crane gold series do a adjustable rocker would also be good but I’m not sure they do or not 

 

I personally would not trust any of the scorpion, home brand, Chinese rip offs at 380lbs at 6800rpm

 

just go around and borrow cavas for the next 3 years or so

Think you will find they don’t come apart, they are mad as a tamper proof not to be pulled apart safety device that simple bolts in and that’s it, if they could be pulled apart then guys in the back yard called bob would be tampering with them and then car manufactures would be getting sued because the spring wasn’t  installed correctly and bobs friends flow out the window

 

if you do pull it apart I think you find the plastic outer casing will be in more then 2 pieces

^^^ oops didnt see the part about mechanical roller

 

My bad, carry on

 

If you ho flat tappet then year 288, if you go roller then i would go the new one but not sure if you can just slap a roller into a existing flat tappet

No need for mech roller. 288 will go 520hp no worries. Tried and tested.

 

The one i listed is same as a 288 only difference is more lift

So can only be better

Its a new of the shelf grind released recently and ill bet it takes 288 spot

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Nope I actually take back the 288

 

throw that in the bin and get either

crane R-250-390-2s-8 this is pretty much a 288 but with lift designed for real men

crane R-256-390-2s1-7 and this is simply better but is getting big

 

both these are cranes new cams with proper lift
