And the rocker pads thank you for keeping them healthy.

Civickiller look at the NA curves, do you think 5200 would work for vtec.

 

I've read that vtec should engage right where hp crosses tq
that's where I put vtec on all the cars I've tuned

vtec engagement looks the same na and turbo

 

*facepalm*

No, no, no.

Whatever you have read, your information is false.

 

Or is it the tq crossing low vs high

I haven't tuned a car in years

 

thats pretty obvious.

 

O Reery?


OP: 380+ on 11lbs on that set-up, thats awesome IMO.

Derrick: I made the same numbers (with a **** hair more trq) with 3-4lbs more. other than the .5 over bore and valvetrain. what else is factoring those numbers, or do those components make that much of a difference?

I think this is a critical component that is often overlooked.


Everything bolded plus a very good machinist.

 

I didnt think .5 over bore made that much of a difference.

now I know..

 

Wrut?

Definitely from the cam setup. And it's only like a 4% drop in torque through that region. Hardly noticeable with a power-to-weight like that, especially in the lower gears where traction is more of an issue - hell, it'll be impossible to notice given wheel spin and where the trans will drop the RPM back to on shifts.

I know it wasn't mentioned in the OP, but this is a stock rod setup. Yes, it CAN rev higher, but another 200-300 revs put more stress on the engine parts than keeping it lower and adding another 5-6 psi of boost most likely will. Gotta balance out torque and reliability.

Ya gat dat right. :p

And I look forward to seeing this again, Marcell. I will most likely be at the shop that day. You bringing the Wes-man again, too?

 

No, you are missing what I have bolded. This is the key to taking average parts and making the perform better than average.

 

For sure.

 

oooo I see, I tend to read over things...

 

Clearances mean a whole ton more then what people think.

 

That's what I figured, it's just not something I've ever seen before. Was curious to see how it felt, the drop probably looks bigger on paper than it feels on the street.

Lookin good as always guys.

 

Congrats Marcell!

I guess what we have all learned from the previous posts, is if you don't what you are talking about, keep your hands off the keyboard. Nothing kills a reputation more than assumptions and statements with no valid arguments.

Now lets get back to the awesomeness

 

damn! Marcell, those are some banging numbers...makes me ponder a lil bit for what to do with my build...whenever thatll happen...lol

 

What did the spec sheet call for ptw? I'm assuming those RS pistons aren't made out of the same material most other aftermarket pistons are made from so they require less clearance?

 

RS machine are cast pistons. So, I would think 0.0015", same as Honda.

 

i want to have your babies.

 

So what happened today good results???

 

^^^I had a minor set back.

After getting everything set-up. The 1st few pulls looked very promising. It made more torque and built boost approximately 500 prm quicker using e85 at the same level of boost, 11.2 lbs. However, we could not go any further because the clutch was slipping. So, in a couple of weeks hopefully I will have this remedied and we can proceed with making more power.

Good news: the set-up and e85 will definitely make 450+ whp with maybe 3 to 4 lbs more boost.

Bad news: I have to get a new clutch to get done.

Also, my tuner (D-rob) will limit the set-up in terms of torque because the block is only using stock rods and cast pistons.

 

nice man other then needing a new clutch lol. im suprised the one you had lasted. 450 will be perfect lol..

 

awsome #'s for such a simple build.

Kinda crazy, bc I'm almost done making my own turbo kit for my 200hp 11:1 comp gsr motor with skunk2 tuner2 cams using a billet 6262. Can't wait to see how it compairs to your build.

 

That sounds like a helluva street build. Start a thread. I would definitely like to see how it turns out.
