That's what the truck coil is listed as - that is one per cylinder?

>Found Trents' setup

Justus - what did you do for dwell times/tables?

These are being used in a lot of builds out there, so there should be plenty of info out there on these.

I run 4.5ms before battery correction in MS3x

Thanks Justus, I'll check it out.

I'll have to figure out something more elaborate for the coil mount - I can't do it like Trents' setup,

Did a short pull in 4th, using the map that gave AFR's in the 11's on the dyno @ 27psi. On the street, it's high 12's @ 24psi Only two momentary instances of knock, though (20:381, 20:796).

Tweaked a couple of load and WOT cells, see how that goes.

EDIT: Won't be able to install the GM coil packs like Trent

Going to order a new air filter & make a new can to fit - I can get away with the 9.5" tapered cone I listed in Simply Volvo's thread RU-5045 flows 1127cfm, VS 1186 of the one VulvaS40T5 is using, which I would have trouble fitting as it is 7x9 cylinder, VS cone (6.75x9.5 w/5.875 base OD) Reference post

New filter arrived, comparison of the last three filters:

XTreme RX-4730XD

[6+5/2] x 6.5 x 6 x 3.14 = 673.53

RF-1015

This filter (RF1015): [6+4.5/2] x 7 x 6 x3.14 = 692.4

In logging, I was already hitting 1900kg/h by 7300, which according to the calculations I found /2 = CFM's, so I was already trying to pull 950cfms through that smaller filter. I'm curious what that meant in terms if turbo efficiency as VulvaS40T5 mentioned.

New filter RU-5045 (1127cfm) 9.5x6.75x4" inlet

Not sure if I can fabricate a can for this one - it's up against the rad

[BlackT5]

What about cutting a couple inches out of your intake pipe to bring the filter back enough for a can?

Yes, I was planning on that - the issue is that there's no room for a can over 7" OD - which means not much air gap between can & filter. Not sure if that would cause a flow restriction. I also need to confirm that my two 3" OD inlets to the can are also not a restriction - don't know the math to figure that one out...

In other news I confirmed that Kingsborne can modify a set of their 8mm Volvo wires with D585 appropriate ends. I just need to figure out the suitable minimum length I can work with.

EDIT: 3.5" wire length, excluding boots

figuring 3" if they can eliminate the 90º off the boot.

Exactly, its not gonna be one of those things that will fail in the 1st thousand miles, it will fail in a year or two when you're not expecting it.

Copper flex section started to seep at base where the collar was silver soldered. Lasted a year.

I made a SS flex version in 3/4", with AN 12 fittings. Took me awhile to find suitable flex tube. Fittings came from McMaster Carr (3/4" JIC). There is an inner chamfered sleeve between the SS Flex and the JIC flared sleeve, so it's not a butt-joint. AN 12 male fitting is braised to flange, and bored to over 3/4" with smooth transition into drain opening of flange to allow maximum drainage of oil foam without restrictions that can cause backup. Replaced the AN -10 - 3/8" male to male adaptor in the block with AN -12 -3/8" adaptor, also oversized to 5/8" ID in the lower half.

(115 x 8000 x (44/14.7+1)) / 3456 = 1064 This is how i calculated it because it says CFM required for a turbocharged or supercharged motor = (Pounds of Boost / 14.7) + 1

Add 1.0 to this answer.

Example: (CID x maximum RPM x #4 ) / 3456 or 1728

That pounds of boost / 14.7 + 1 means pressureratio from compressor map and pounds of boost is boost pressure.

I calculated that your engine would need with 28psi boost about 1000cfm of air and similar air filter as i have. Your current air filter is too small and its weakening your turbos performance and turbo is now in higher point on your compressor map.

Thanks for that - I didn't understand the +1. Indeed, in that case my filter is too small - I calculated 998.5 CFM as you say. I'll have to look for larger filter... again

I have never seen any compressor maps for the PTE turbos, and wouldn't know how to read one if I did

Edit: how does one read a compressor map ? How did the restrictive filter I had impact the area of the map used? I'm flowing around (1900Kg/H) 70lb/min by 7300rpm, running 24psi.

[140CID x 8500]/20839 = 57sq.in

CFM required: [140x8500] x [24psi/14.7+1] / 3456 = 930 cfm

My old filter (RF1015): [6+4.5/2] x 7 x 6 x 3.14 = 692.4 cfm

New filter (RU-5045): [6.75+5.875]/2 x 9.5 x 6 x 3.14 = 1,129.8 cfm

Pressure Ratio = 2.7 (boost/14.7+1)

The closest I can find is the GTX3582R which has the same compressor sizing with a smaller turbine inducer (68 VS PTE6262's 72mm)

When air filter is restricting the point in compressor map will be higher as turbo will have to spin faster. The problem is bigger if you are maxing out your compressor. But if you are like in center of compressor map problems is not that bad.

Its little bit complicated to explain. That PR ratio in you compressor map is not just boost. So if you are like boostin 2.0bar and you add that atmoshpere pressure 1 to there you are in point 3.0bar PR but in real life intercooler and air filter are causing also restrictions which will add to that PR ratio. So if intercooler is causing like 0.1bar pressure drop your point will be 3.1bar PR you know.

Hope you understand what i mean.

What kind of oil temps are you seeing?

What kind of oil temps are you seeing?

Don't know right now. Once I have my new sensor logging device, I will be able to add back all the channels I had with Innovate/Logworks, oil temp included.

Hope you understand what i mean.

I get the gist of it.

Thanks Aaron. I'll spend a little time with that & see if I can establish 3 reference points.

[lookforjoe]

GM coils will likely be positioned somewhere along these lines:

making an aluminum two piece cover to mount the coils & replace the existing cover.

Coil packs will be on standoffs. there will be standoffs for the two plates. there will be openings for the coil wire to pass through.

Cracked header has got to the point where to car is running like shit, so I have to deal with that ASAP.

[854TGA+]

I wonder if the header wrap tape caused (corrosion) issues? I've heard mixed reviews on that stuff.

[blkaplan]

you might want to try to reroute that filter to the inner fender area. Seems like you are out of room in the engine bay and that filter looks pretty crowded.
