Yea, I guess you are right, If more air goes in, more air must go out and the wider piping in itself will help free exhaust flow at the higher RPMs

 

I did that before

 

My only complaint I wish I hadn't went with the v band. They are actually bigger than a bolt together collector flange. I knocked the clamp off a few times.

 

Very nice, Ray!

And thanks for the advice, i wont go the Vband clamp route. Im also gonna use header wrap to help keep the radiant heat from escaping the longtubes to heatsoak the motor.

 

If you don't already have SS clutch line upgrade, it might not be a bad idea if you put longtubes on

 

I thoroughly enjoyed reading this whole thread.. Awesome build man! Good luck with your tuning venture. I also may copy some of your ideas for cooling intake temps, meth injection, etc.. I'm in south FL and it gets stupid hot here in the summer. In for the numbers after tune!!!

 

Thanks man, I appreciate it. Happy to have given you some ideas on what to do with your build. Meth Injection is a great setup to have, colder AITs and a higher octane bump to avoid/negate detonation seemed like a win/win for me and its one of my favorite mods on my car.

 

Thanks, The Clutch/Flywheel combo I bought from Z1 came with a free SS clutch line, I did not install it yet but I will soon.

 

---UPDATE---

Recieved some books I ordered to help me understand the basics of Tuning and Engine Management systems, read them both already in 4 days. Very great reads if anyone is interested in tuning their cars themselves or for more general knowledge.

Also some good news, Seth my old tuner at Rad Motorsports is back for a short time here in Hawaii so I will be doing one last and final tune for now. One tune with meth injection and one a street tune without. He said its will be fine using my Laptop and Tuner cable to tune (This way i can have a copy of both to flash on my own if need be and modify my tune on my own as I learn) That being said, I will hold off my longtube header install till i move to Texas. Tomorrow evening will be when this will take place. I will be sure to post a video of the dyno and Dyno sheets for both tunes. Shooting for 445-450whp with Meth and a safe 425whp with conservative timing without with my Fluidampr+ 3.12 Combination.

 

Good Luck Tonight!

 

Thanks!

I'm also going to change my mixture with my Injection kit instead of straight 100% Meth, I'm going 30/70 Water-Meth as water will help increase the cooling further in the combustion chambers and slow the burn speed of the flame during the power stroke.

 

Just keep in mind a 30/70 mix by volume is more than 30% water! Methanol is tricky stuff to mix with.

 

Thanks, Resmarted. I am aware. I haven't mixed it yet cause im still on duty, was gonna do it tonight or tomorrow morning. Might end up using less water then, maybe 20/80 water-meth mix.

 

It's weird how mixing fluids works... especially methanol. The problem isn't so much what initially the mix is, so much as having a consistent mix down the road lol. So just try to leave a bit of margin in afr for that. A little rich (point or two extra) will be fine. Don't worry about "leaving room" in the timing though; if your next mix has more water, you'll actually want a bit more timing.

Overall though, as long as you don't rely on the water meth too much it really won't matter much.

 

Soo a bit disappointing yesterday, Weak part of my build during Dynoday yesterday was the clutch, The Z1 "Mild Performance" Clutch is only rated at 350 wheel torque and it started to slip on me during the meth injection tune past 375tq.

With the Pump only tune we put down a conservative 421whp-355tq. 11.3 AFR.

With the Meth map, my numbers were relatively the same 435tq-373tq, 12.2 AFR, No knock! However on the dyno sheet, after about 3500 rpm, my gains in the powerband were from 5-20whp and tq with a sacrificed peak HP due to the slipping clutch, So we had to retard a bit of timing to keep the car within the limits of the clutch. This time around, my mixture was 70 percent Methanol and 30 percent distilled water by volume.

This is all I will be doing for now till I move to Texas. I made sure I asked a lot of questions to understand why Seth did what he did to the maps and challenged myself understanding further that what I did know beforehand. In the mean time, I will be getting used to the Osiris Tuner Software, practicing data logging a monitoring the cars performance.

Those are still decent number I'd say.. I have that engine management book as well that has been siting here collecting dust on my shelf haha. But you motivated me to start reading again. In for the numbers with the LTH and new clutch.

 

Yea. Thanks. Car is still plenty fast. Main focus right now is a new clutch once in Texas then retuning on my own with the longtubes installed. I really want to also buy a 2.87 pulley but I would be overspinning my SCi blower with an impeller speed of 58112 with the Fluidampr and a 6600 redline. For now I will just enjoy the car as it is.

 

Go ahead and over spin it!! Won't hurt it any.. I over spun my SCI, SI, and now my TI trim blower. When I dont have belt slip, the blower is seeing 65k.

 

Haha, we will see when I'm in Texas after next month. Definitly would love to do it, as well as finaly installing a Fuel Return system.

Got my clearing papers for the PCS move outta this damn island yesterday so most of my time and money is tight at the moment.

 

Just an update, been busy out-processing and taking care of things to get out of Hawaii and move to Texas, where my new duty station will be. On my free time ive just been getting used to the Uprev software and further developing my learning curve with self-tuning doing data logging and making small changes to my Meth tune to see the results, whether good or bad. That's how you learn.

Only new addition to my car is a Sparco seat. Pro 2000 GRP Tech. Pretty sweet seat compared to the OEM clothy seat. All I need is a helmet and i'm ready for track days in the Lone Star State.
