Thumbs up

Hey Rich what size turbo you running in that beast? Its a wet set up huh. I'm thinking about going bigger and switching to a cooled set up. I'm running a .70 compressor with a .96 p trim right now. Looking good Rich...!!

Lookin great Rich! What's the specs on the FMIC. LxW(thickness)xH of core. Also what size ID is theIC piping? It reminds me of what I have now. Mine is L=20", W(thickness)=3 1/2", and H=7 3/4". This is core specs. Thanks Garret

LOL! ****, right before I took my car down for all this work the BNRs were running great in the cool weather at 17 psi. I told Ihor that now I can redline my car (unlike our last 'race' where I had breakup at 6800 rpm) so let's have a rematch. He declined my offer, saying that his wideband wasn't working. Keep in mind that his cobra isn't that modded, yet is making 500 rwhp/540 rwt. He's going to need his nitrous for this setup, that's for sure.......

Hi Garret,

the core is 19x12x4, for a volume of 864 cubic inches. By comparison, my old M2 Large SMIC was around 700 and the RE Regular V Mount that I was considering running was only about 475. Piping is the standard 2.75 inches.

It's a 35R variant with pieces of three different Garrett turbos inside. 1.0 hotside, standard .70 comp. Should be efficient to 30 psi

What are you and Ihor doing this weekend? Let me know, I would like to come and take a look at the car. Later..
I won't be around this weekend, although I might be working on it next week sometime. I'll let ya know.

I've always run my probe in the dp and found it to give accurate readings. I also didn't feel like going dual probe b/c I already have enough gauges inside my car

I've wondered where people tend to draw the line with respect to "efficiency". Do you need to be 70%+ to say you're efficient, or would one claim 65%+. This is one of those things I'm still trying to sort out. Where do you draw the line?Thanks!

Perhaps I should have said 'Won't melt into a metal lump at 30 psi'

Here's a quote from the 500R thread re: efficiency:

Originally Posted by Zero R
It will be available in T4 only. Rear housing options are .82, 1.00, 1.06, 1.12 Divided. Our 500R will offer almost identical response to the 35R with a much more efficient top end. So if you were looking at a 40R this will offer roughly the same power with quicker response. If your looking for something that has more topend than a 35R but quicker response than the larger turbo's this will do it. It is more efficient across the board and especially at higher pressure ratios. Example 15lbs on a 35R 74% eff. 500R 77%.. @18lbs 35R 72% 500R 75%.. @20lbs 35R 67% 500R 75%.. @25lbs 35R is out of breath, 500R is 73%.. It will support up to 75lbs/min. at a pressure ratio of 2.75 I can even broaden this for you further if you opt for the anti surge compressor. The best part is you wont have to sacrifice response for this setup. It will be very similar to the standard 35R in response. I spent a while finding this combination and I think it will be the absolute best offering out there for those who want response and power.

There is no line really it is simply the more eff. you can run the better power you will make. Running a very eff. at 18lbs 42R is good for power at 18lbs, flows well, doesn't heat up the air too much from compression. That said it wont be worth the eff. in the response lost if 18lbs is your only goal. It's best used running higher boost where it maintains the good eff. still. I try and target the best size to offer the best response while maintaining good eff. It's all a compromise your going to lose one to the other it's just a matter of what you are willing to give up, for what your willing to get. Run a 35R at 18lbs and your 72% eff run a 42R and your 77% I bet the 35R car is much more fun to squirt around town in. Hope that helps some.

I had pretty much reasoned that if you were in the 70% + islands, then you were pretty efficient. However, compressor maps usually dip really deep into the 60% range and I've wondered if people knowingly/decidedly run at those lower levels, or is that just asking for trouble?

Zero R - the 500r sounds like a dream for power across the board (if you've got the port work to match)
Goodfella - sorry to thread highjack

I would say you should try and size the turbo to stay in 70%+ range for as long as possible. Some people do hit the 60% range. I wouldn't say on purpose though. While they could make more power if they were in the 70% range maybe they want the quicker response the smaller turbo affords since they spend most of their time in that area and not so much time at maximum boost. You have to look at the use of the vehicle.

I can't believe I still hadn't replied to this thread. What can I say... Looks very clean and well put together just like the entire car. I said this on another thread and I'll say it here.... Don't go for anything less then 20 psi

Keep on eye on that 90 degree oil inlet fitting. Mine was bent and so it sisn't seat flush and leaked badly. I ended up replacing it with some earls stuff. Dang, that 4" pipe looks crazy!

Oh, and i'm also using the FC AST bypass cap and I still have to refill with water once a week but in the begining it was every day for two weeks. I may have to do an AST again.
