Sounds like a vender

 

your right, go for the pulleys that look cool.

 

How about you provide some data proving the Speedsource pulleys add a significant amount of horsepower over the other brands of pulleys?

About the Speedsource pulleys and use on a street car.

 

I'm not saying I haven't researched or thought bout them but for my application don't seem worth the hassle of trying to obtain, as I am not part of the mazdapseed racer program and I do want to keep my AC and I do not race the car Agency pullies seem to be proper for what I am doing all esthetics aside.

 

they do a lot more than eliminate the AC, both the water pump and alternator are slowed down more than anything else being sold

so you lose some weight and some parasitic drag at higher rpm

I have my idle set at 1150 rpm to maintain sufficient alternator charging with them if you go that route, never have any charging or battery issues

 

Moses gives his expert input again.

 

Nicely done fella... nice to see...

So, what exactly have you had done to the engine then to get that power at the wheels? Also, you mentioned Petits new super charger, so they have the replacement in the pipeline do they?

 

Its an estimation based on conversations with Cam, full build list and baseline runs. I truly dont know what the exact power to the wheels will be but that is where im guessing it will be. And yes Pettit is doing a limited production run of a new SC kit, they have a prototype in the middle of testing but nothing is commercial plained for a while unfortunately

 

Quick inquiry to anyone that can maybe shed some knowledge.

Hearing some controversial information regarding different sets of injectors, I'm sure the stock injectors will be fine for my application here until I go FI but since I have it all tore down figured now would be the easiest time to upgrade them.

I was researching the I.D 2000 and I.D 1000 for the upgrade which people run on our cars, but was informed that high impedance injectors won't work on our car, is this true? Any insight on this.

Or would I be better off contacting MM as I know he supplies and upgraded set as I will probably be contacting him regarding tuning as well. As it appears upgraded injector require tuning as well as I was planning this anyway

Or any suggestions to something I haven't thought about yet.

Again I know this upgrade isn't necessary for my NA build but I won't be NA for long just wanted to get this upgrade out of the way now while the block is apart

Thanks

 

You need high impedance injectors. You sure don't need ID2000 for anything. To big for an RX-8 setup. You could go with ID1000...but that would be a ton of fuel

I would stay stock until you turbo and then change them depending on youe build. I ran 4 ID750's with Blue OEM primaries and it worked well.

 

Yeah they seemed a bit excessive seems the most popularly is a 600/750cc setup respectively and is good for 400WHP just looking for a good set, plus I want to get it out of the way now so I don't have to worry about ripping everything apart again later

 

Seems like a waste of time to tune it if you are going turbo soon. The tuning will take a lot longer than swaping injectors

 

do it when you go FI. Like Dan suggested. The injectors are not that hard to change out.

 

Regardless of injector upgrade I was going to get tuning if not for the only reason of increasing OMP flow rate, also I don't like the idea of running a modded block on an OE tune.

 

The only good reason to do it now would be to tune the new injectors NA to get them dialed in. If you aren't doing it yourself your tuner will hate you for the amount of fiddling with the injector size and latency to get them perfect NA. Small errors will really show up with injectors that big when your pw's are that small

 

Good point, just looking to get as much as I can out of the way now so its something I don't have to bother with later, plus I did just get them back from Pettit's clean and flow check service so I might as well use them for a while.

 

Made some more progress last night, engine bay is back together, starting to get more parts in later this week will post some pics, ran into an issue last night though if anyone can help me out here I'd appreciate it

These clips broke when i removed the bay wiring harness from under the dash and without them the harness falls all over the place but I cant seem to find them anywhere to get new ones.

 

Engine bay progress



Some more motor assembly, now just waiting for my LIM to come back and its ready to all re-assemble,

 

What are you doing to the lim?

 

Its getting powder coated, was bead blasted yesterday and there baking it today so I should have it by tomorrow or saturday at the latest

 

there is other work you can do on it

 

Patience, not on an N/A and I would want to test it on a mock LIM first, get a used one cheap just incase i brake something

 

Nice build Carbon8! Lots of good work!!

One quick question(not trying to be a jerk either)but why is this N/A build in the Major Horsepower Upgrades section?? Maybe I missed it somewhere,




.

EDIT: disregard, I seen that your going to FI in the future.

 

lol, and technically when it comes to a Renesis there is no such thing as bulletproof

couldn't find anything on the harness clip, it may only come installed on the harness from the supplier

 

Where would you like it to be placed?

Considering the extent of the build this is where I placed it as it doesn't follow conventional aftermarket bolt ons and when finished should produce substantial power increase and reliability as far as an N/A reny can at least. Now that's compared to N/A motors won't come close to an FI build but this is also my stepping stone to my FI build.
