So you delayed the power by rpm in all gears untill 3500 rpm? If so then you should be fine. If not then sending full boogie in 4th and up (say from 2500) would likely cause some issues. 1st and 2nd really shouldnt need any reduction except to prevent wheelspin.

Basically. My power/torque is really low under 3k, after 3k is when it all wakes up. I usually dont really go wot unless im in 3rd past 3k... That's party the reason too even though I still spin tire, just not as much as before.. later this week when im at my buddies house ill pull up the tables and take a picture so you guys know what i'm talking about. keep in mind i peak at 25psi, and redline at 6900 rpm.

Update: I took a look at my tune and I was totally wrong about dumbing the car down in 1st and 2nd lol. What we did was lower the power/torque below 3k so there isn't much of an issue with clutch slipping. I make all my power past 3k and top end

Hey Kyle,
For clarity, you could install this kit and run only 93 if you wanted. Also, say you're running an E30-40 blend in your vehicle typically and you're travelling, and you don't have access to E85 wherever you are. Our kit allows you to fill up with 93 and dilute out the E85 dropping the ethanol %. You do not have to be specifically tuned for a particular ethanol content, you are able to run any blend. The Ethanol converter box and GM sensor work instantaneously with your ECU to correct constantly. The new platforms perform their best at E30-E40.

We made 400whp on stock block, internals, and trans, your power goal is definitely achievable without sending a rod and piston to the moon. We have countless customers in the 330whp range with our upgraded turbo kit (GTX2860) and full bolt ons. Feel free to reach out to our [email protected] for any direct questions you may have!
Wow thanks for such an awesome and quick response much appreciated yeah I didn’t know what the l15b7 was capable of as I’m new
To these motors I’m used to my k20 but I’m very interested in the flex fuel kit so thank you for this answer

Do you still have a stock clutch in your car?
Yes I do. Eventually I will upgrade it, but I don't really have plans to anytime soon. And I haven't taken the time to research all the different clutch options and what makes the most sense for me.

But I did get the W1 installed this weekend and I'm running the W1 ktuner base map and the clutch was holding up really well when I got on it (93 pump)

Sweet dude. I definitely need a clutch before I go big turbo, but that won't happen for quite some time either. I'm in no rush to be wasting that much money right now.. As far as the clutch I see a lot of people getting the type r retro fit, but I think i'm gonna go with the ACT organic full face and single mass fly wheel whenever the time comes

Yea I couldn’t afford getting a clutch right now and honestly don’t even want the headache of that install yet lol. Only reason I even got the W1 was because their $100 off sale ended at the end of April and once I got that stimulus check it was basically a no brainer for me.

yea skimming through the threads I’ve seen people running many different clutch options. I feel like In the beginning I saw a bunch of people go with clutch masters 350 or 400 fx. But haven’t seen those around lately.

I heard people had a lot of problems with that clutch. I trust ACT so ill go with them. To me I see no point in buying basically a stock type r clutch when for the same money and can buy something a little bit better.

Yea I’ve seen a lot of people mention the ACT clutch too. I’m a big research guy, so I’ll exhaust every avenue and put it in all in a spreadsheet before I make a decision.
But I’m going to start with the ACT :)

Just installed fx350. Engages low but wow, the car feel so much better. I’m not having any chatter or lockout. 400 more miles to go before letting it rip. Running tsp stage 2, prl downpipe/frontpipe.

Why is ACT a little bit better? I was under the impression that it was just the reverse. I have the type r clutch and am amazed by it every day.

I put my trust more into a reputable company that has been making clutches for years with proven efficiency. Just a personal opinion on what i'd personally like to run

Hey guys, just to add a little input on the type r clutch, not sure if any of you follow L15B7allturbo on IG, but he has a type r retrofitted clutch and is currently dailying his 500whp Si. Not sure if I’ll ever even go that high so it’s definitely what I’m gonna go with.

Interesting. I guess I gotta do some more research lol.... Eventually once I pay off the car and it's mine I wanna buy a separate engine and build that and throw it in the car with the big turbo lol. That'll be a few years down the line though
