The Life of the Black Knight

nice man

 

Sweet. I wanna ride in it!!

 

^^^ Me too. Wait, I'll go take a ride right now

 

now i need to get a ride in this, congrats man

 

Grats Milo! I remember when you were getting frustrated with the 300whp barrier in BK1...:ddirty:

 

Good numbers man!

 

Very nice!

 

Thanks guys

Haha. Yeah I remember that.

 

Congrats buddy! Very nice. :bigthumb:

 

That's sick man, congrats on the suby powwah

 

Congrats Milo!

 

That's some huge power, milo! Congrats man!

 

Thanks guys. This is keeping me plenty happy

 

so without re-reading 57 pages of thread. Can you give us the quick update on your setup now?

 

It was cool running into you Milo. Congrats on the new numbers man.

Car sounds/looks awesome!

Didnt BIg Davids make 505whp with the FP Red?

Those are decent numbers for the amount of boost you are running. But i still think there is more in it.

Isnt that turbo CLAIMED to make 500whp?

Only reason why i ask is i have a customer trying to buy that turbo, and i kinda want to talk him out of it now. if that turbo cant make 450whp at 26psi, how the hell is it gonna make 500whp?

PS: You should change your first post where it says COBB TUNED BY SCOTT SIEGEL AT BATLGROUND

 

hope you didn't mind me posting your graph.

 

If it's not enough power for you Milo, there's always the GT30R.

 

I was told that it would be between a 7cm2 Red and an 8cm2 Red in terms of spool and power. Now comparing it with a 7cm2 red that Scott recently tuned, he had me on spool be ~100rpm or so, but otherwise the plots we dead on. All the older plots that Doug had tuned had me beat by a lot.

The AVC-R controls my boost, and on the street, I am set up to run 1.9kg/cm2 (27psi) at peak, tapering to 1.85kg/cm2 (26.2psi) at 6000rpm and 1.8kg/cm2 (25.5psi) at 7000rpm. When Scott tuned it on the dyno, I'm not sure if he had a taper. If he did, it would certainly affect peak power. Maybe he could chime in.

Done

 

Not at all. In fact, thanks for posting it up. I have been asking Scott to do it all weekend.

By the way, I think plot #8 was the cleanest one without any breaks. Could you post that one up?

Hahaha. I don't think I am going to change my setup. I'm happy with what I have

 

And that's all that matters....

 

Maybe you should have Doug retune it, maybe he will see something Siegel is missing.

 

LOL@Matt.

 

I didn't mean it that way but there has to be a reason that its not making 500whp. That turbo should be capable of 500whp. If its not making near that then something is wrong. Its easy to overlook stuff.

 

I didnt take it that way either. I just found humor in it.

It is 40hp off where it should be as a minimum. Doug's SZ55 with stock inlet size made 470hp on C16. That was even with TGV's in it and shit.

 

I agree completely. Compression test came back fine so I am pretty confident that the engine is good. There are a couple things in the car that could use improvement:

1) Downpipe: I have a cat. It's high flow, but it was on my WRX for a couple years and has been on the STi for a year and a half. Not sure if it is still good or not, and how much of a difference there would be if I was catless at these power levels
2) EM: Switching to something with an adjustable knock threshold would allow for a more aggressive tune

Concerning the turbo, it's making enough power for me, at least for now. Switching to a whole different setup is really not worth it for various reasons. First off, I doubt there is a whole lot of power to be gained for the amount of money I would need to spend. The car is probably already close to the threshold of reliability. Secondly, even if I spend the money, who knows if it will make any more power. The problem may be with something else.

For now, I am not worried at all. As long as comparable tunes on comparable setups make comparable power, I know there is nothing wrong with my car. Now if Scott tunes a similar car and it makes a ton more than me, then I'll be concerned.

If Doug wants to play with it, he can have at it.

 

Lets just take it to the drag strip and see what kind of trap speeds it runs. That will tell us how much power it is making for sure.

 

Doug was here while I was tuning. Maybe these cats are a lot more restrictive than we thought... There is not much left of the table.

Siegel

 

I'm running lower boost in higher gears. I don't think I want to run 28psi in 5th or 6th. I'm sure that would affect trap speed in a big way.

 

I was there when Scott tuned it, like almost all the tunes done here at Topspeed now. I don't think there is anymore I could do to it than what Scott has already done. Scott and I frequently work together on some of the cars that come in so its not like we both didn't take a look at while it was on the dyno. It made the power it did and would not make anymore safely. My guess would be he is running the smaller meth nozzle which wasn't allowing us to run higher boost and more timing. Maybe switching to the M15 meth nozzle and a retune will net more power.

 

Dang... you ninja posted me... Wait aren't you on the dyno now, get back to work.

 

:slap:

 

^ lol

you could throw a smooth-designed U/P for an extra 10-15hp...?

wait, milo doesn't have many stickers on his car... he needs MORE stickers it WILL make him t3h f4st0r!!1

 

:rofl:

I have stock headers and uppipe. Not sure how much there is to gain/lose there

 

Well, from the butt dyno on my car...going from the stock header/up from an STi to the ported stock pieces, BPM cross over and the Random tech up was a HUGE gain in around town TQ/response, noticeably faster spool and it feels like it has more top end power.

Otherwise...it just might be that the kitties are stopping it up at that power level.

The 0~5hp difference we are used to seeing might only apply to the 'smaller' turbo cars. Aka stock turbo and anything less than an 18G/20G.

I'm sure someone has a 3inch bell mouth catless that Milo could borrow.

 

TurninConcepts did a really nice write-up dyno before/after on IWSTI that i read a few days ago. makes some very good points about the stocker not being "quite there"

 

I didn't realize you have a catted downpipe Milo. With a catted downpipe and an internal wastegate I am willing to bet all I own that there is 50 hp being held back.

 

I have an aps 3.5" downpipe you can borrow if you need to, BUT it has divider and could lead to potential boost creep

 

I doubt I'm going to get an external wastegate. But I really want to drop the cat and throw it on the dyno. I expect it will make a noticable difference with the motor pushing ~27psi.

Thanks for the offer man, but I think I'm going to wait till I get a replacement of my own.

 

Are you concern with the noise of the EWG? If so you can simply route the dump into the downpipe. Makes a HUGE difference in the noise.

Yeah I can see the cat being a huge restriction at over 22 psi. You are trying to push so much air at that point.

 

Noise is not the concern. I just don't want to have to get a new wastegate and uppipe. Eliminating the backpressure from the cat should help promote engine longevity. The external wastegate should help some but for all practical purposes, I have reached my goals with the car. 430whp is plenty fast. Dropping the cat will probably give me a little more, but I don't want to start breaking things.

 

Now your life is like a giant, eternal void....

 

:rofl:

 

That makes perfect sense and I'm happy that you are happy Milo. I wouldn't want to change out all that either. Only reason I'm doing it to mine is I have to replace them anyways when I pull the engine for the 2.5L swap.

 

Over the weekend, I ordered an Invidia V2 catless downpipe and an Invidia N1 racing catback (Thanks Sakari). Being unresonated, I wonder how loud/raspy it will sound. Can't wait till they come in. I'm going to put a wideband bung in the downpipe and have it installed as soon as possible.

 

Can't wait to hear it. Congrats
