Thanks man, should be an interesting build!

YES!!! You are my hero.

An in car adjustable power steering controller would be WICKED. I am going to contact them after I get done with work.

Thanks man.

 

Let us know what you find out ...that looks very cool

 

In other news...


I'm extremely excited to announce that TurboSource has come onboard as a sponsor!!!


They will be supplying my build with an Adaptronic standalone ECU! This will take some strain off my budget as well as give me peace of mind on picking an ECU. I'm very excited to try the Adaptronic unit as they seem to have excellent support and are working hard advancing the capabilities of these units.

I will most likely be going with a universal "wire-in" ECU.


Also still waiting to hear back from the power steering controller guys. If I can get a hold of one of those then I would be able to ditch the stock PCM/ECU completely and run the car just off of the Adaptronic.






Sidenote: I will be reporting any posts unrelated to my build. This is not the place.

 

Well you could just move the stock ecu inside like you stated previously-that way you don't have any extra costs. You really can get rid of alot of unnecessary wiring in the loom such as inj, ign, sensors, etc. That's how I do it, but since you don't need anything other than ps perhaps it's better to get that controller. I have never seen it before so I don't have any thoughts on it, other than it'll help with the wiring headaches of relocating the stock ecu wiring.

 

Congrats on going REW and with the sponsorship !

Your going to love the 8 with a REW and wonder why you didn't swap it in sooner.
Also I've had positive dealing with TurboSource.


.

 

I know it might be a little early in the build but have you decided on what transmission you plan to run? FD 5-speed or the RX8 6-speed?

 

Congrats on the Adaptronic, it is a great unit. I'm saddened to see it has to come to you thru a Turdblown sponsorship but if that is the only part that Elliot has in your build then that is good. It also sucks that you will be using a product from Mazsport Scott as well but I guess you have to do what you have to do to get where you want.

Will you be using a fancy race transmission?

 

The Adaptronic will not be the only part used from TurboSource. I'll be purchasing my Dash and a few other items from there as well. I have no doubt that all transactions will go smoothly.

For the mount, I based my choice purely off of the product, I feel it is the best offering at this time. I am not in a position where I can afford to sacrifice performance on my build because of reputation. I have ordered from there before without issue and I expect this transaction will be no different.


I will use the stock transmission until it breaks. At which time depending on funds I will either swap in an FD transmission or a Faceplated Dog Engagement Close Ratio T56.

 

Word. I wish you luck. Is using a T56 on and REW common? or will that be something that is experimental?

 

It's not common but it has been done before. There are adapter plates available.

 

subscribing, esp if it involves TT1 content at around 2800lbs and 450whp or so

 

I looked at numbers again and with 260mm non-dot Yoko slicks it's more like 500WHP and 2800-ish.

 

leave a little cushion to avoid blowing over on the dyno or coming in under weight of course

that sounds SIIIIICCCKK!!

 

Yeah that is still like 50lbs over and 25whp under haha.

 

Alright did the actual calculation for classing.

So the Adjusted power to weight limit in TT1 is 5.50lbs/HP.

With modification factors of:

-0.1 (Weight Bracket)
+0.3 (Rotary Engine, 2 rotors or less, 1 turbo or less.)
-0.2 (Dog Ring Engagement Transmission)
+0.3 (Between 244-267mm Non-DOT Slicks OR between 250-275mm DOT approved tires)

Minimum weight: 2750 with driver
Maximum RWHP: 529.

So if I stayed at about 2760 (with no fuel to be safe) and 500WHP I would be comfortably inside the class. I have a feeling I won't be running that kind of power though even though this build will be more than capable...




EDIT: Forgot one modification factor as kbrewmr2 pointed out, here is the actual setup:

-0.1 (Weight Bracket)
+0.3 (Rotary Engine, 2 rotors or less, 1 turbo or less.)
-0.2 (Dog Ring Engagement Transmission)
-0.7 (Non-DOT Tire Compound)
+0.3 (Non-DOT Tire Size between 244-267mm)

Minimum Weight: 2750 with driver
Maximum RWHP: 466

This is much better since I really didn't want to run at 500RWHP anyways. 450 will be a good solid target, I'm guessing I'll be able to make that kind of power at about 18 to 20PSI of boost?

 

you missed the hit for using non-DOT construction slicks though (-0.7). The tire width stuff is independent of that since you could have 13" slicks, or 10" slicks, or 7" slicks...

at 2750, with that in mind plus the other stuff you mention I get 466 max allowed whp which is still ALOT. Or if 529whp is still the goal the weight would need to bump up to 3068lbs.

 

Ah okay sweet. Yeah looks like you are right, which is good because I'd much rather run it at 450whp.

 

Round 1 of my part out is underway, thread is in the FS section.

/shameless plug

 

Just wondering, how much does your car weigh?

 

Well, the last time I weighed it was more than a year ago and still had a ton of stuff in the car. Doors weren't gutted, still had all stock glass, still had power windows, still had heat and A/C, no wiring was taken out, etc.

It was at 2750 without me in it and half a tank of gas.

My new goal is 2500 without me in it and with half a tank of gas.

 

nice, how hard is it to install the lexan glass?

Is there a DIY on it somewhere around here?

Doing some of my windows at the moment.

 

No idea, I've never done it. I am going to delete the front windows completely, and replace the small rear ones with lexan which is easy but I will leave the other glass in, will replace as a last resort. I've never installed lexan before besides my sunroof insert which is flat so I wouldn't know.

 

Fair enough, I'm just doing the front passenger one at the moment, fair bit of weight, door card and all the window motor accessories!

2500 is pretty light! Team is the weight reduction king, what is his weight?

(I assume he reads all the posts in the racing sub-forum)

 

He has autocross rules that he has to stick to, so he has to get really creative most of the time to remove weight. I literally have free reign as far as weight reduction goes. I can sit in the car with an angle grinder and just cut **** out if I really wanted.

 

Yeah I am aware of the restrictions with the autocross guys which makes it even more impressive.

I will be in a similar category to you race rules wise, however at the moment I am just doing super sprints which is not racing and no restrictions. Still learning.

Keep us updated on progress.
