All I know it's I wish I was that fast. Stupid turbo!! Lol. Ok I'm sorry turbo. I take that back. Stupid driver and no traction. I wish I made 11s. Mid 11s is my goal though.

any vids of said 11.6 passes?

Yeah I will try to post them up tomorrow.

What he probably means is that the duty cycle on e85 cannot be compared directly to gas. Duty cycle will be correct for E85 since it's based on what your ECU is commanding the injector to do.

He explained that the calculations for the duty cycle will be off since we are using e85 and scaling it differently. My duty cycle is at 115%, which he explained it really isn't that high.

Yep, it's not going to be over 100% since that would mean it's continuously open. :tup: If you're calculations say it needs 115% does that mean you should get bigger injectors?

Seb said I didn't and I was good. I might someday get the ID1300's when I take the boost a little higher just to be safe.

Alright guys here is a little video of my trip to the track. Wish I could have ran faster but I will get the launch down with more practice. This weekend is Street Car Takeover here so I will most likely be getting some good roll racing in.

Great Vid's ... Great Passes ... :tiphat: ...

Started my A2A install, I can't believe how crappy stillens kit is....so complicated compared to just using an intercooler. Whoever designed that intake manifold should be shot. Let's hide three bolts completely underneath the intake manifold and hope whoever buys this kit has a magical elf that can climb up underneath there and loosen/tighten those bolts...I bought a long 12mm wrench specifically for that manifold. I chopped it up, welded it back together, grinded on it... so i could reach those bolts, it took forever. I was thinking about hacking up the aftercooler in the intake manifold like other people have done, but I would have definitely gotten a ton of aluminum shards in the engine.

gonna be back at it tomorrow

done venting

Sooooo, I have a surprised for you guys. I refused to acknowledge the fact that I had to send out my blower to have an impeller upgrade. I decided to hell with it and upgrade to the largest known trim for the V3. It's specially made for C07 corvettes and a couple of the Vortech reps didn't even know it existed for some odd reason.

May I introduce you to the Ti-Trim. same internal gear ratio, larger 3.75” inlet, larger and differently contoured impeller. It's got a much higher CFM rating and in the corvette world, you are expected to build your engine when upgrading from the Si-trim to this. Will I blow up my engine? I guess we'll find out in a couple days. :ughdance:

Seriously though, it's supposed to double the boost, so this is uncharted territory as of now. I have a feeling that it won't be too crazy, but I've seen a 350z run this and he was @19psi (was forced to build his block after about a year of tracking it). I have a couple solutions if it gets that point, but I'll revisit those if it comes down to it.

^Damn, go big or go home I guess. :tup:

:eek2: :usa: :leghump: :postwhore:

I'm not looking to break records here, but Seb will give me some of his time while at SEMA. Hopefully we can work something out and possibly have a better alternative than swapping over to something like a V2 blower.

My a2a isn't Topgunz kit but very similar, I would recommend any you that don't have a great tuner to use Seb! I had my car tuned by a different tuner the first time before I blew the engine, he spent hours trying to get it right because I was never happy with it but it was never right to me. Seb has only done 4 flashes on my car after we found some problems and the car runs way better than it ever did from the other tuner.

Evening guys
is anyone running a aftermarket radiator with the tredstone ?
if so which one and have you seen any fitment issues
tia

Not needed unless you track the car hard. I never had a heat issue. Oil cooler is much higher priority.

It will run cooler than the water setup because your air intake temps will be much cooler.

I live in AZ where we were in the mid 90's till just last week.
Water temps with AC blasting, no over heating, even middle of the summer with stock radiator. But I do run a 34 row oil cooler.

Thanks guys
Good to hear :)

Hey guys, sooo I just finished the install of the Ti trim V3 a few hours ago. Many thanks to TopGunz and Evan for answering all my noob questions.

I have some vids, but wanted to see what you all thought about this:

On the first startup, the first thing I noticed was a violent amount of vibration in the cabin. It's odd because when I'm on the throttle or in 'Drive', the vibration goes away and the car drives normally. Once I put it in park or reverse, the vibrating is noticeable. I also notice it when starting the engine too. (refer to the YouTube video links below)

After driving it for about 10 miles, the vibrations got a lot more tolerable. Definitely a lot less now, but it's still there.

I already checked all the bolts and everything looks fine. I did notice that if I held down the supercharger with my hand with some pressure, the vibration will lessen.

Any input would be appreciated. I'm assuming this may be normal behavior for a break-in period? I've never had a brand new V3 blower, so I'm not positive on my end. That or this blower is just straight up violent.

(Pay attention to the cranking. You can hear it's rough. I can def feel it a lot in the pedal.)

Video of Park and Drive: https://youtu.be/YE_eAcdQrag
(Notice there's a 'wum wum wum' noise in park, but when the rpms raise in drive, it's gone. Reverse vibrates like crazy btw)

Really hard to tell anything's wrong in those videos. I have to ask. You put oil in the sc right?

I had somthing like that it was the stillen manifold vibrating on the strut brace

I spaced it up with washers

Sent from my SM-G920F using Tapatalk

Sounds normal to me but did you make sure the supercharger isn't hitting the frame below it?


Sent from my iPhone using Tapatalk

Yeah I just realized it's very hard to tell from the videos. Oil is fine and it's not hitting anything. The vibration is very noticeable in person. I noticed that it's only happening at lower RPMs.

Yeah I had a similar issue but my intake tubing was up against my strut brace also. I spaced it out with washers and the vibration went away. Just check everywhere where the piping could possibly hit any of the frame or metal on metal. And of course makes sure the bolts on the supercharger and bracket are really tight.

I'm seeing 75% so far. Making 8psi

Let me know Dyno numbers if you ever decide to dyno it please :) should be interesting.

Dyno results will be coming as soon as all these issues get settled.

I hope you dont run out of fuel up top if that trim pushes a lot harder. There is always a limiting factor when going for more power. Definitely keep an eye on your fuel pressure gauge when they are tuning it. Better yet would be to get a camera on it.

Also, make sure they have a boost reference hooked up to they dyno. It is AMAZING how many shops will not get this out of sheer laziness.

Yeah, I'm road tuning it for now. Seb just sent me an updated tune, but I was still in the 11s at almost-WOT. I'm carefully watching the AFRs, so we'll see how it goes. I'll be on the dyno as soon as I'm ready for E85 and I'll make sure everything is good before we proceed.

I'm going to jack the car up again and check all my bolts tonight probably. Just trying to figure out this damn vibration issue. It's pretty much only happening in reverse now.

Is your car a automatic? I have a vibration in reverse also.

Same here, I'm going to check with Pat@level10 about it.

Yep it's the 7AT. I had vibration before, but not to this extent. It's literally shaking my cabin.

Sent from my Pixel XL using Tapatalk

Please let us know what he says!


Sent from my iPhone using Tapatalk

Will do!

Hmm I completely forgot about the transmission. I'll check everything over again and then maybe give them a call to. They are only 40 mins from my workplace.

Sent from my Pixel XL using Tapatalk

I spoke with Pat@level10 and he doesn't think is the transmission. He thinks is the exhaust making the clattering and vibration through 1-2 and reverse. He asked me to bring it in so he can check it out but since I'm about 2 hours away I told him I'll take a look first.

Interesting. I'll take a look at mine as well.

BTW, Sebastian sent me an updated tune and it looks like my AFRs are freaking out up top.

At 7k rpms, my car starts sputtering and my AFRs on my gauge start jumping everywhere. You can see on the graph that it's all over the place.

What's causing that ?

Sent from my SM-G920F using Tapatalk

He said briefly mentioned that it could be my fuel pressure dropping or an issue with my primary O2/WB sensors.

I ran another log to confirm the issue, so I'm just waiting for him to get back to me now.
