You think a 93 octane tune is slow, get a 91 octane tune. :eek::rofl2:

No Thanks.... LMAO You folks in Cali should all be running E85. 91 craptane would be a no go.

When your engine builder says to turn it up. You should make 1000hp no problem. :eek::eek::eek:


:ugh2::ugh2::ugh2:

I run flex fuel, e85 99% of the time. I like to run a tank of 91 through the fuel system every once in a while and if I take a trip and e85 isn't available, I can still run 91. That's one of the reasons behind my wastegate set up.

Another reason for the wastegate. I can run spring pressure or low boost on 91 and spring pressure, low boost or high boost (when I want to turn it up) on e85. :driving:

I have 12psi of boost with the boost controller off. Setup this way I should be able to run 24psi of boost with no issues with the boost controller.
I run flex fuel also. Only way to go.

My spring pressure is 10 psi, low boost is 13 psi (the max I can run on 91), high boost, wastegate doesn't open and I run 17 psi on e85.

Mark asked me why I wasn't running 30psi of boost with the GT30 twins. Simple, the stock intake won't take it. LMAO... His comment, what a waste. He already told me the next
thing to break is the stock crank at around 1200hp.

I assume you'll stay below 1200hp then. :tup:

I will be out of turbo way before then.

I may be out of tranny, as my boost shouldn’t exceed 18# :wtf2:

Swap a q60 transmission in the car

This is great news glad everything is working out are you making the trip with the car?

Noop, it is at MA-Motorsport at the moment. It will be on it's way soon.

Exactly the same one as I already have :iagree:

Alright fellas, time to add another feature to this thread! I've searched for a bit on the forum but all the responses were opinion from people that have never had them installed and "they ruin the lines of the car!" whatever that means.

Looking at the Varis Air Vents to go along with the Varis Cooling Bonnet 2. Looking at the position though, it looks like they will be bringing air flow right above our intercooler into the blow off valves so idk how much they would actually help. And coupled with the hood with vents could that cause TOO much airflow at say half mile events when you get upwards of 170+? HotRodz has them so excited to get some real opinions!

Go back into the thread and watch the video on aerodynamics and air flow. You need to figure out what the cars purpose is, instead of throwing money into parts.

I have a problem with front end lift that starts at 120-130mph or so. Be careful with what you do. You can make it worse if you do the wrong thing. Most off the shelf parts are just for looks and do nothing for the Aero. Get with Hotrodz, he knows someone who can help you out with your Aero.

I smell some upcoming diff explosions. End of March or early April, a few of you want to do a group buy for a Winters quick change diff?

Those videos are on post numbers #2478 and #2579.

I don't think they are needed as of yet. Transmission is more likely to chit the bed. MA already sells the modded subframe to fit the Winters quick change diff.

Ohhh, I was just hoping a few would jump on board. lol. I think that's the only way my car is going to handle 1500hp.

Hi Ryan, aero is a quite complicated and I have done some research and talked few pros on the subject for a circuit track car. The referenced videos are excellent resources.

So if you aren't going to do more straight line events you want to stay as streamline as possible. A vented hood is a must for the Z. The only aftermarket hood I would buy at this point is the INGS+1Super Taikyu Racing Bonnet. Was specifically made for track car 370z's in Japan. There are very few in the US. The placement of those vents are in the exact same spot that the Trackspec hood vents are supposed to be place. The Trackspec vents were designed through CFD and most everyone I have spoke to or read reviews about indicate about a 10* drop in temp to go along with the benefits of additional downforce without increasing drag. If you want to improve the efficiency of your hood vents then you will need to duct the air coming into the front of the car. It will move air more efficiently through the engine bay and the hood vents.You will probably want to get fender vents or vented fender to also reduce high pressure areas caused by the wheel wells.

Spooler runs tall and wide tires so his ability to lower the car is limited. I have seen enough data and CFD diagrams to show lower the car by one inch will lesson drag, but I'm not sure how much if any over 140 mph. A flat floor is necessary to decrease drag significantly.

Also should consider a front splitter of about 3 to 4 inches. Again there is the benefit of downforce, increasd drag and improved front end stability vs lift and increased stability at higher speeds.

Lastly, in the rear I would stay with duck bill or shot wing like the Nismo or Amuse. If you are serious about getting rid of in the rear of the car you will need to shave your rear bumper. Rear bumpers are huge parachute if you don't have a flat floor. I had mine shaved and you can see it in the video I posted.

Anyway I hope this is helpful. I know some of it is extreme as it is all about what are you chasing in the end. My car will seldom see more than 140 so maximizing downforce for most tracks is the goal since I have enough power to overcome the drag deficit.

Thanks fellas! I didn't watch the videos initially bc they are so long BUT they had so much great and useful info. REALLY glad I took the 45mins+ to watch both. Especially the first video in regards to my front end. It's a little overwhelming but just means each part I add, I need to extensively research and will do so! Especially considering the cost of so much of them. Thinking of avoiding the air ducts. I mean the filters are RIGHT where the LED lights on the v2 nismo bumper are, anywhere else it appears it won't do much. I MAY be able to go below, but truly wonder how ridiculous that would look. lol I'm not needed to be professional, Just looking to have fund. Sometimes in a straight line, sometimes in curves, and sometimes to the grocery store. lol I think I'm more concerned about looks but not sacrificing performance and THAT's what I need to keep an eye on. Especially considering the APR GTC-300 that I really am in love with.

Bob, you never cease to amaze me and thank you so much for taking the time for a detailed response! I love all your knowledge and we are lucky to have you as part of the FI brotherhood :driving: Your car is well beyond what I think I will ever be. Right now I wanna go fast and just look pretty. lol! But from those videos and what you've mentioned, those ducts would have been a waste. I REALLY like the idea of ducted the airflow from the front grill into the intercooler. That seems like such an awesome concept. And I will certainly look into the hoot you mentioned! I really loved the looks of the Varis Cooling Bonnet 2 which to me looked like it would drastically improve temps, but not sure on the drag side of things. So more to look into, but thank you for pointing me in the right direction!

No problem brother and I appreciate the compliment as I am just doing my part to share what I have learned from others.

Well that is the challenge. I chose to still be a street car. Going to far into the race car category is not what I want to do. Sounds like you don't either. It's a balancing act.

Let's just look pretty, have a little fun, and live vicariously through Bob ;)

We can still "Go like HELL". We just won't be perfect.

I am doing the tune time dance waiting......... With one bad knee I am having to do it with one Leg/foot.

My dancing shoe is worn out. I gotta take a rest break.

Well not today. Looks like he was working on an Audi that made 991hp.

Looks like it will be next week. Ah the agony.

:tup: :driving:

I am in severe pain right now. NO 370ZTT to drive..... I am miserable as chit. This boost junkie needs his fix....... The Vette just doesn't cut it.

^ for that reason, i am thankful i get my kicks thru lateral Gs and not longitudinal

Once you experience a turbo car, a boost junkie you will become. I can do lateral G's too. In a proper Turbo car you will get out with the shakes. LMAO

I truly am sorry to hear that.

I know you are doing what you want for your own sake (who doesn't) but sharing what you have shared so far, even though none of it is really proprietary, it is very valuable and will save anyone who cares to pay attention heart ache and money (youtube personalities aside). I for one am glad you've had the financial and quite frankly, more importantly, the mental fortitude to stick with this platform.

As they say,
Pimping Pioneering ain't easy

That's my 2nd Job!!!!

I owe, I owe, off to jigalo I go. To make extra money and pay for my build, I hoe, I hoe, I hoe, I hoe.....

I have been very fortunate these last couple of weeks, They all wanted riding lessons.

I was selling a bunch of NA parts when I boosted my Z and making late runs to Fedex to ship them off. My wife now says i sell culito "***" at night to pay for car parts. It's now an ongoing joke for her everytime i do something car related. LOVE IT!
