Innovate Stage 2, Race to 300WHP w/o E85
 

So my question is what is the best/most efficient way to hit 270-300whp on my FRS without e85.

(I live in Maine and E85 is extinct here, lol)


My set up: 2013 FRS
Innovate stage 2 sprintex 210 supercharger (stock injectors and fuel pump though)
Stock headers
J2 quad catback exhaust (I have the catless downpipe but haven't installed)
Perrin CAI
Dual Radium catch cans


Any tune suggestions/what other upgrades should be done to hit 270-300whp?

I am very new to tuning so forgive my ignorance.

Race gas

Call Mike at Moto East, depending on where you are, he might be a drive away. Master tuner with good experience with these blowers. You'll probably need a good set of headers too, there's a few for sale right now on the forum if you want to economize.

Thank you !

Ditching that OEM header and replacing it with a catless one, should help free up some ponies.

Header has major role .
Mike tuned both 210 and 335 sprintex.
You can call him about upgrading to 335

Just for reference, I'm dyno-tuned by Mike.

Sprintex 210, w/ 69mm pulley, on 93 octane. Full Catless Exhaust, UEL.
Can't really add much more timing on regular gas. Even with e85, Mike has told me it'll reliably make 290-295. Water Meth should put it about 275ish.

@moto-mike tagged since you've been requested.

think about custom SC cams

Interesting, I thought somewhere I saw someone had over 270whp on pump gas, but I might be smoking crack too. Either way I think Mike is a good bet for maximizing what you have.


Edit: I think it was crack, or E85 rather :) sorry

@Rifle @bfrank1972 thank you guys, very insightful.

I sent Moto Mike a messege. I think I will probably get some new headers soon as well.

Any recommendations for headers that will add to the car prof ordnance wise but not tooo too loud? Or could I just add a resonator to counter act it?

With the J2, you're going to be stupid loud with a header, no matter how many resonators you add.

I would recommend an EL header for FI application/performance gains. It's what I've switched to now. Tomei EL is what I'm using.

Thank you. That's unfortunate about being stupid loud lol.

Do you use a catless header? Also is a UEL louder then EL?


I have been talking with Moto Mike and he thinks my best option to hit 270whp ish is WMI with some new headers and smaller pulley

I wouldn't say that they're anymore loud than each other. The air is more free flowing in an EL and thus has the performance gains. W/M and a 69mm pulley. Call it a day.

I see. makes sense. Ordered a 69mm pulley today! Probably will get W/M and new headers in the next few months.

Any supporting mods needed for the W/M or 69mm pulley?

and last question, what WM kit / Headers would you recommend? for maximum power gains

Header is truly up to you. I went Tomei just because I saw one up for sale. JDL/Tomei/Nameless/Ace all have pretty well tested headers.

On E85 we usually hit about 310 whp on the West Coast. We even have an article in D Sport Magazine (November 2014) going over the build of what it took to hit 310 whp.

On 93-94 octane I do not think you are going to be able to hit 300whp on the standard 210 kit. I would expect about 270-280whp on 93-94 octane might be doable.

Thank you for the response! Do you have any recommendations for how to hit 270-280whp? /any specific delicious tuning tune

I think the three keys are: good tune, water meth injection, and a good header. Also think about whether you want to run a catted or catless header. And with FI I always recommend in person dyno tunes, especially when trying to push the envelope.

Thank you! Good advise. I will be doing a in person dyno tune a week from tomorrow! Headers and WMI within the next month or two

I would suggest a good set of headers, as this will really help the exhaust ports flow better from the heads. ACE Headers and JDL UEL are great options for this, along with many other options on the market.

A decent exhaust system from the headers back, but you do not need to go over board on this. Just something to keep the velocity and flow of the exhaust gase velocity up and unrestricted.

We have found the stock air box works rather well since it keeps the air cool entering the engine. Also you will need to remove the snorkle and we would suggest adding an HKS bumper scoop to intake temps down. Cool air will be more dense and therefore allow more air molecules to enter the engine. So it is important to keep those temps as cool as possible.

Lastly we offer a 69mm pulley option to get the boost up a bit more which you will need to have the intercooled kit for. Then run 94+ octane on a little bit of a custom tune from us for this configuration and you should be right around 270-280whp.

Thank you! Slight problem though, I have already ordered the 69mm pulley (I have the stage 2 intercooler) but the best pump gas available within an hour of where I live is 93+, is this okay to run? Or should I return the 69mm and get a 70 or something.

The 69mm is designed for the intercooler and 91+ octane fuel. So you are good to move forward with what you have.
