Supposedly within 3% 

I had an option to go to a dynojet with a less experienced tuner, a mustang dyno, or this one with a very reputable tuner. Even though he didn't have to change the tune much other than taking a couple degrees out of the timing, I went with him because I want experience on my side when positive manifold pressure goes into effect.

M30 swap for my Olive Drab Vert!


60lb Siemens Dekas, 3.5" down pipe that reduces down to 3" from the down pipe all the way back. And at the moment just a generic cone filter


And thank you Otis.

Positive manifold pressure is within sight! 

Today I got in my piping for the wastegate and started the process of plumbing it in. I also had some oil lines made so I can get oil to and away from the turbo.






I also have skipped posting a few steps showing progress on the gauge plate but here is the nearly finished part. Keep in mind there will be 3 gauges across the top and other items on the bottom half. I am considering making these for the community, let me know if any of you would be remotely interested.

Down pipe progress!!!!!

Added a V-band at the bottom and finished the day with a wrap. Ignore the welds, I did!

Positive manifold pressure: CHECK!


Did a little test run at 1am down some country roads and HOLY HELL! This car is scary fast and I have driven some fast cars in my day. 14psi +/- and it pulls like it is being chased by every demon in hell! I cant wait to get it back on the dyno for some new numbers. I am going to guesstimate 415whp I hope I am right.


I will post some videos in the following days but for now I need to make sure she is ready for the WNC picnic. 


LIFE IS GOOD

Videos will be up hopefully this evening. No one is willing to record yet. They have been to busy clinching butt cheeks


Accelerating onto the interstate under 3/4 throttle and boost near 12psi the car looses traction and the rearend wants to slide out at 60+mph. So much fun

I would offer you a place to stay but I live in the Mountains which are 3+ hours away from the vintage. Otherwise you would be more than welcome to stay at my place and hangout at my shop.


Jeff thanks for holding the camera. I cant wait to get this thing tuned correctly and realize the actual potential this set up has. Hopefully next time you ride in it I will be making more boost and have some wider rubber on it.


I will probably need to upgrade my tuna can suspension to a more hardy Halibut setup


Using the video time as a measure it looks like I made it from 60 mph at 0:55mins to 100mph at 1:01 so my 60-100mph time is 6 secs. Then I hit 120mph at 1:04 which puts my 60-120mph time at 9 seconds. Kinda slow..... I will have to work on that. I am still learning this "new" car and power.


The wastegate spring is a large green spring for my 44mm Tial which is rated at .8bar or 11.6 psi and I don't have a boost controller as of yet so this is running on the low side of my boost goals.


And just so you know the gear change was from 3rd to 4th and this is still with just minimal tuning on above 90 cells on the VE table.


After doing some research on 60-100mph times and reviewing my video I am impressed with the time. 1st point, I started at 60mph from a deceleration and all vacuum.... The official numbers posted by supercars are derived from a continuous pull from 0 mph up to a speed well above 100, so no loss of boost/power. 2nd point, I shifted during the pull even though my gearing will take the car past 100mph in 3rd gear. SOOOO I will be attempting this time again correcting these two very important details because as it is my current (messed up) 60-120 pull is already in the company of cars such as the Ferrari 512m and the Noble M12 GTO-3r which both do it in 5.1 seconds. I would like to see my car do better and post a 4 second pull at 11psi which will put in the company of the Koenigsegg CC8S. Doable? You betcha!

I love driving this car! Except for last night. After 3k miles on the new engine my coolant system decided it was no longer happy with the half ass bleeding job I initially did and I found my self sitting at a gas station last night trying to add and bleed the system so that I could continue my enjoyable evening ride.


Another attempt today for the 60-100mph. Same tune, same low boost, just different approach. I feel like I can definitely do it faster even with the current tune and boost. But in this video I am dead on 5 seconds flat.




How do you embed this thing?

Nice!
