Sick setup man, Sounds like it does good.

Yeah id definitely see about routing the copper gate back to the t70, basicly to use as a backpressure relief as im sure that much power being pushed through the t2 you will start to see high back pressures and im sure that gate is dumping some of the pressure you could use to spool the t70 up.

Very nice setup overall man and yeah cant believe you fit all that in there. Good job.

Nice setup, and enjoyed the videos

WOT transitions and then kissing the rumblestrip....nicely done ahaha!

Walperstyle

do you have a dynograph for this setup?

PS. I would highly advice having some kind of heat shield between the turbo and BMC.
This is not safe

Damnit Walper, why didnt you say something sooner? I melted the master 4 hours before your post. Lol. I knew it would happen esventually anyway. So now I just ordered pathfinder master to get the lines on the other side. Thatll free up some room for a proper heat shield.


I have a dyno graph that ill have to post later. It makes the same peak power but has about 80 ft lbs more down low.

So here it is, some apples to apples comparison on the same dyno over at Lowcash Racing in Phx.

Both pulls were using pump gas 91 octane.

The skinny lines are Old Tq and Hp with the stock log, and ebay t70.

The thick lines are the New Tq and Hp with manifold, s15, and t70.

The maf was moved to Draw thru and ecu retuned around this.

Everything else stayed the same on the car, only changes were in tuning and boost controller settings. The new setup needed much more fuel and some timing pulled out. The other variable, the electronic boost controller. In the old setup it was on the one and only 44mm (10psi spring) with some added duty cycle across the board to get to 14 psi. Even with the controller it took forever and a day to spool that turbo. Once it hit it felt great, and if you can keep it in the power band, its all gravy. On the new setup, the 44mm (still 10psi) was in charge of regulating the little turbo, and the second wastegate 38mvs (7psi) was charged with regulating the big turbo. I used the controller and added duty to get the big turbo back up to 14psi. I plan to change out the 38mvs spring to 14psi to free up the controller and get it over to the 44mm to get more spool out of the little turbo. Since its just spring pressure, its slowly opening as boost builds vs having the controller hold it shut til the desired pressure.

Blah blah blah...Dyno sheet time.



Its clear there is more torque spread throughout the rpm band, with the biggest jump being about 80 ft lbs.

More hp is available everywhere except the last 500 rpm, as Duty was pulled back just a tad to promote shift.



Since the dyno, the spring on the little turbo went from 10psi to 14 psi. Can definatally feel more low end umph, still no boost controller on it tho. That lil black mark on the sheet is my guess as to Tq gained from the spring change. Who knows, could be wrong.

Added some duty to the big turbo and put it on 17 psi. Again can feel a differance as the just keeps pulling up top. Compressor is a little louder too.

Had to close the gap on plugs, blowing spark out. went down to .022, feels so smooth now.

Melted plastic Bmc, teeheeheh.

thats a sick setup, great job on all the work that had to go into that.

Got the pathfinder bmc with the lines on the other side, made tons of room between down pipe for heat shield. Also made some new Dot brake lines. They fit nice and are hid away, cleaning up the fire wall a tad.

Thanks man, there is just always something else to do or try. While the bmc was off I also took off the rear subframe and did solid mounts. Slammed the frame to the chassis and cut the chassis for more arm clearance.

I was able to make a stainless heat shield today. Going to add a piece to fully cover the down pipe and get heat away from coils.

that is a nice heat shield. great job on the manifold. I'm going to suggest this idea to my buddy who is running a similar sized turbo, this looks like it would take out the lag problem all together.

if the rep system was still in place, you could bank on another +1

Hit the Drift and Drag tonight. Tech line was super long, took forever. Wanted to drag race just to see what shes doing, but there were soo many draggers there, wasnt worth the hour wait in line.

So I drifted. Car felt great, super responsive and didnt break anything. Brakes are holding strong, heat shield is doing its job. Now its time for new rear tires.

anything new with the setup?

FutureFab

Alot has happened since last post. Ill try and touch all the major bases along the storyline.

Hurt the det transmission at the track one night a week before Xdc round 1/2 season opener in Phoenix. OUch. Scurried quick to find a trans local. Found one and picked it up monday night. I still had stock sheet metal front end that was more or less swiss cheese, so this was the perfect time to add some tubes.

Now you can see the setup on the motor.



It was tuesday and round 1 was on friday.I stayed up each night til 3 or 4 in the morning after I got off work. I had to build the tube front, remount the radiator and Ic, put the swap back in, adjust the Ic piping, add front tow hook, battery cut off, hood pins, clean up my wiring, and adjust alignment and some other loose ends. I also moved the rack forward and built a oil pan for more ground clearance.



Then I needed saftey gear. I had to get a seat, new harness, fire suit, fire shoes and socks, helmet, and gloves. Luckily we sponsored Andy Lee of Bondurant School of Driving with a road race cage for his World Challenge Camaro (he later won rookie of the year and took 2nd overall in points this year) and he hooked it up fat with most of the gear I needed. Thank you Andy!





So it was thursday night and it was becoming clear that I wouldnt make fridays race. What a bummer. I was in a slump. Friday morning I get a call from Vitaly Sopkin and he asked if he could borrow my catch can to get his car to the race. Since I wasnt going, I let him have it to get him on the track. He also said one of the guys at the track needed his cage modified to pass tech. He came from out of state and really needed it done asap. So I told him to come down to the shop. I went to the metal store and picked up some Dom to make his diagonal in his hoop. I made the bar and got him passable for the track. After I got him out the door i started chipping away at my car again. Later that day it was close, I still needed fire undies and driving shoes and a fire extinguisher. It was now or never. At 3pm on friday I went and dropped 360 bucks on Alpinestars shoes (the only size that fit me in the store) fire undies and a fire extinguisher.

I went back and kept working on my car. At around 10pm I registered for Saturdays race online. I dont know what took so long but it did. I was up allllllllllllll night no sleep finishing the car. I remember mounting the seat and just being delusional from lack of sleep. I made the mount and welded it and inch off. cut it off and made it fit. At 830 am the car was done.

I went home quick, showered and went right back out the door. I drove the car to the track with spare tires in the car along with all my tools and jack. I got my wrist band and proceded to tech. Made it just in time and passed. Then drivers meeting, a break, then practice. This was my first drift competition and there were some pretty serious cars there from all over. My first practice session sucked as I was trying to get used to the course and what not.

After first practice was an hour break, I went and ate some burger king, first thing I ate since the previous night. Still no sleep, but a second wind was coming.

Second practice started and I was feeling it. It was a strait line to the first blind right and I was hitting it in 4th. The car felt really good for an eyeball alignment and just being thrown togeather. I saw Garret N. in the line and we decided to tandem. He led I followed close in 4th. He got a lil squirrly and I was close and dedicated to my line. We met.







Fuuuuuuuuuuuuuuuuuuuuk.

I just made that.

I went back to the pits to check it out.

Evil Dan and I ripped off the hood and headlight and all the mechanicals were still fine, even the ic pipe, it just had a dent. My tube front wisker was bent into the tire tho. Big buddy Gerald came to the rescue and HeManed that Ish back out of the tire. Back into the car and back to the track. Well I got there just as practice was ending. I asked for just one more run but they said no.

One more hour break before qualifying runs. Dan noticed my right rear tire was burning a tad more on the inside, so we cambered it out a tad real quick.

2 qualifying runs to get into the main. I qualified 13th. Woohoo! Im in! And they only took top 16.

Pics I found on net of my mangled car. Wont let me save and upload tho.

http://s746.beta.photobucket.com/use...ml?sort=3&o=63

Practice before the final Dan was spotting me and telling me I needed to snap harder and sooner. I did and he said it looked great, just do that. Third practice was over and as Im going back to pits my car is dying. WTF. I didnt have a gas guage (or any guage cluster for that matter) so I figured its out of gas. 20 min til top 16, Gerald runs to get me gas. He makes it back as they are calling my name on the loud speaker. Eeeeeeek! Dan runs over and tells them im out of gas, just need a min. We get some in there and head to the line. Dan keeps filling it up with multiple jugs.

Couple guys go then its my turn. Im following first pass. Dude misses a shift and duffs me up. I had to slow down not to rear end him He grabs a gear and pulls out a tad, I get it into 4th but im off my line. I end up going off track at the 3rd turn.

Next run im leading. I stand on in hard and hit all the apexes Fasssst and wide. It was awesome. But I was now going too fast into the reducing speed area and straighten for a second. Dang, I blew it. I got booted first round.

It was super fun and Id do it all over again in a heart beat. More to come...
