Shawn, I would make sure to use aluminum crush rings on the turbo coolant adapter fittings. I didn't trust the rubber/steel one that came with the NPT adapter. P/N 900 123 007 30 (14x18x1.5) worked well for me.

Great job on the exhaust work btw. It's unbelievable how quickly you get things done!

Very nice work. I am glad you get these things done quickly too. It really keeps the motivation high.

Thom

Great work Shawn.

Not too sure about the stock intake with a GT35 though... Interested to hearing how you get on when you get to adjust boost settings.

Thanks. Crush ring already ordered. Following your setup pretty much exactly.

Amazing how much can get done by doing a little every day. I go out to garage a bit every day. Great place to relax and unwind from the daily grind.

My intake is mildly ported and it is a concern. I will be looking at it closely during first dyno runs. I think it is going to be fine but we shall see.

Thom - I would love to see more pictures and details on your motor!

Sid was running essentially the same intake as me and hit 522 hp. I would be interested on his input on the intake. I found a few others pushing my power with the stock intake. I have looked at making my own but am going to test the stock intake first.

LR has some flow numbers on their website, does anyone else have any flow numbers they can share?

Thom

Sorry but I take hp figures posted on here with a barrel of salt... What was Sid's 100-200 kph time with this engine? Or 100-150 kph?

Not sure but here is his 1/4 mile info from his signature: 11.43@125 best mph 127.19

This data is pretty consistent with his Dyno chart.

I believe that this equation is accepted as being pretty close to the mark. I still don't quite get it?
Is the equation to figure out hp just the mph and weight of the car? How does that account for aero values?

I've had my head and intake flowed, on my engine the intake even easily outperforms the head.

Just the mph and weight. It's a pretty accurate measurement. Unlike a dyno, you can't fool the trap speed.

Tbh, for this type of car (that you can't really launch and get the mph going) it is very conservative IMO. If you think about it, the measurement is based on decent drag cars. I have found that the mph is pretty consistent whether it spun or bogged.

I personally can't see how any other measurement could be considered more accurate. To move mass from a dead stop (point A) to another (point B) is the measurement of horsepower.

I definitely take dyno numbers with a grain of salt. Unfortunately, we can't all line up side by side and run. So we have to use some measurement. For me it's the quarter mile trap speed. Which is also used widely amongst most enthusiasts.

In regards to the intake, I didn't have a chance to try a different one with trumpets. I only had a few slight mods to mine. Maybe for testing, Shawn could try the one I have at the shop. It would require a 928 tb.

Let's see how it goes. I'll be curious, because I'm using a modified stock intake on my 16 valve. So if Shawn's picks up hp, then in theory, mine should also gain.

Thanks, can you share the flow numbers?

thingo

The intake flowed about 295cfm stock, 320 extrude honed, the head was about 195 stock to 245 ported.
They were flowed at different places and I can't tell you the exact method at which they were measured, but they were both shops that pros use, so I consider that a reasonable comparison.

Please lets not debate this here!

Also, your quote in your signature was in reference to a specific situation. Thomas Jefferson never intended it to be used in the generic.

refresh951

This data would be very useful if both were measured on the same setup (say SF600) and at the vacuum (say 28" water column). Any chance you can find out?

blown 944

There won't be any debate from me. I've learned, and placed him on ignore. I won't even bother responding to what is quoted.

Anyway, if you'd like to try the intake I have here, just let me know.
