http://www.speedmachineperformance.c...tCode=HP300001 I have it on my turbo, its a little bit of work trimming it to size, but it is thick and really gets the job done. I'm sure you could source one within Canada as well, but I bought mine from speedmachine...... |
Wow Aaron... very nice fabrication and a very nice build!
I dont know if i like the paint scheme but who cares about the color, its going to haul ass. Cant wait to see it ina action!!!!!! -Ben |
Somewhere north of 500. The GT40R really comes alive at more then 17 PSI. |
Yeah i'd think for sure you'd crack an S4 iron on pump gas with that much power.

I know that, i'm just thinking it's gotta' be hard to not detonate with a gt40R on pump though. What octane do they sell in canada? I'm paranoid so i'm gonna' run methanol injection for my 60-1 set up that will be done probably sometime next year.

Some updates... Yesterday afternoon a little tuning took place. Finally got some time to get out of the city and actually see some real boost. First the low load was cleaned up so that at light throttles an in vacuum, A/F ratios are rarely leaner then 13.5. This made a huge difference in the way the car drives, not to mention fuel consumption. I'd go as far to say that it drives nearly as easily as stock. You can cruise all day at 2000 RPM without issues with the A/F ratios in the high 14s, and the car can be launched at 1700 RPM without any major drama. Slowly we worked up to 10 PSI and past, bringing the fuel down to reasonable levels. At 10+ PSI, the car is a beast. Even with A/F ratios of 10:1, the thing just hauls hard. At 14 PSI the turbo really comes alive and the car looses traction in 1st, 2nd and 3rd. It's my guess that at less then 15 PSI, the car is easily a mid to low 12 second car and that's with A/F ratios probably costing 80HP. Once things are a little saner at 11.5:1 under 10 PSI and probably 11:1 or high-10s at above 10 PSI the car will really start to pull. No real videos right now of the tuning, but here's a little teaser showing the real response of a ball bearing turbo: http://www.youtube.com/watch?v=H1MryAt1dw8 Count how many seconds it takes to stop spinning after the car is turned off. |
Wow your build up looks great. Looks like you put a lot of time into this. Congrats on finally getting her all together. But was it really necessary to build your own wrenches too? J/K

wow ... sounds amazing !!!!
cant wait to see it at the track, drag strip and on the street !!! dont be shy with the videos !!!! |

Here's the mockup with the wastegate runners tacked back into place. There is way too much plumbing here! And there's still more to add. Next time, I'm going back to NA...

The next engine for my car is a 4 rotor...Been planning it for years, but generally I don't talk about it. Years ago I spent quite a lot of time with the machine shop discussing a 4 rotor 12A, but now with kits available for the 13B I can save a lot of headache by using 13B parts. It's not really that expensive, all things considered.

ahh but just imagine it will turn into a 4 rotor high compression turbo with two gt40R turbos :devil: hehe you know you want to Arron :D and we all know you could and it would be freakin amazing!!! and imagine the sound mmm i think i am in rotary bliss...
ohh could you get a sound clip/ video that i could really hear the exhaust in? i am very curious what it sounds like with those silencers? |
very nice you are always proving yourself above and beyond

The 4 rotor will be NA for sure. ohh could you get a sound clip/ video that i could really hear the exhaust in? i am very curious what it sounds like with those silencers? Updates from yesterday: Finally someone noticed the oil filter! I was smiling the whole time I bought that because I was just waiting for someone to complain. :) A little more tuning yesterday. The car has lots of fuel for probably as much as the turbo will throw at it. At 13 PSI (current wastegate spring, no controller) injector times are less then 4 mS and A/F ratios are still in the mid 10s. I'm slowly cleaning up the car and aiming for high 11s before 10 PSI, low 11s at 13 PSI and high 10s at higher boost. Timing is currently very conservative under boost with a linear progression from 15 degrees or so around 8 PSI ending up at 10 degrees at 13 PSI and above. Certainly there is more power to be made with timing but I'll cross that bridge on the dyno and not the street. The car is rapidly becoming too fast to safely tune on even the most remote and deserted roads. Rolling on the throttle will result in loss of traction in 1st, 2nd and 3rd gear at nearly any speed. Boost control is rock solid. It spools to 13 PSI then just sits there regardless of load without a hint of creep. I must say that the datalogging feature of the Nexus gauges has made this process very simple. Of course the Microtech does datalogging, but it's far more convenient to grab the Nexus remote and step through a run while tweaking the fuel map at the same time. Currently I have a 512MB SD card in the remote for logging which is about 30 minutes worth of recording. Very handy for the drive to and from work to clean up cold start and cruise. |
Very impressive fabrication aaron. I too have the gt40r on my FD and it is a great turbo. On about 15psi, which is right around 420whp on a ported motor...is good for around 11.8@122. I am still trying to figure out why you are having such an issue with traction, what size and brand of tires are you running? Do you have suspension mods, especially in the back? Have you thought about running atleast the Nitto 555 radial?
|
I don't get it. Why not race gas and 25-30 psi? Isn't that like a waste of a turbo to do otherwise? Or am I missing something here?
|
wow ... u better be going to sevenstock!

Real long term testing will resume shortly though sooo.....:dunno: :) |

So why not? Just because you can run something to the ragged edges of its capability doesn't mean should all the time. I know my setup isn't going to be pushing 20+ pounds until I feel I've gotten my money out of it :) |

1. Race gas is expensive 2. Race gas is not available at any corner gas station 3. I don't need a 650+ RWHP 2nd gen (who does?!) It's PLENTY fast right now, and once I turn the boost up to 15+ and get the richness out of the current tune, it's going to be scary/dangerous fast. More then 30% throttle on city streets is terrifying.

Basically with the zip-ties yes. Its holding up well though - I had fitted it to the old turbo before blowing that engine, so it hasn't seen a *tonne* of run time, but its been on and off about 4 times so far (those stainless ties are sharp!!! :lol:) and the holes where you "sew" the ties through haven't enlarged at all.
Not exactly, considering that whether its in its effciency range or not - that turbo will pull like a frieght train at 10-14 pounds. |
Updates....
The DEI heat shield is dying a slow death. Where the inner surfaces touches the turbine housing, all the aluminum coating has flaked off. Every time I was the engine bay I end up with a shiny aluminum coated towel. Will it get worse? Don't know at the moment but it certainly does not look as good as it did in the original pictures. I'd have to say that because of this, I am not happy with the product and would not recommend that anyone else spend their money on it when there are other well known blankets that can stand up to rotary exhaust heat. I'm going to send a letter to DEI asking them to make it very clear that the product is not rotary compatible. As for the tuning, the car is coming along quite nicely. I've been datalogging nearly every day and working out the kinks in the light load map in the hopes of getting reasonable gas mileage. Currently the car cruises in the high 14s/low 15s most of the time, falling to the high 13s under light acceleration. Because of the general leanness of the map it's taking some time to really dial in the cold start (there's only one chance per day to work on it), and as the engine breaks in fully I've needed to tweak the idle a few times. Nothing out of the ordinary really. In general the car is terrifying to drive under WOT. It's still running pig rich under boost in the low 10s but it's slowly coming around as I've been leaning out the map. Soon I'll need to book some dyno time because as the A/F ratios improve, power is improving dramatically and the car is too fast to safely tune on the street. This Friday (tomorrow) I'm going to make a trip to the 1/4 mile to make a few easy runs and just see what the car will do right now. Primarily I'll be looking at MPH at the end of the 1/4 mile as it's the best indicator of potential. I'm not going to beat the car at launch yet with things like the anti-lag until the A/F ratios are a little more sane. |
I have used the "turbo blanket" material that SMP sells. It sounds as if it is very similar to the DEI stuff you are using. It lasted about 500 miles on my car. It was a joke and a waste of money. It burnt up to a thin crisp of nothing.
Best bet for a turbo blanket is the Gotham Racing one, it is more expensive, but it works tremendously! |
Aaron, ur a nucking fut. Awesome dude.
