Thread: SR20VE 4-2-1 "budget" header

So will this be the final design, or is there more testing to be completed?
If so, do we have an estimated time on headers being built?

Excited

Love this guy...always a GREAT answer for everything.This thread is awesome.Lots of great info,and q&a
It s also good to know that the VE R&D will continue for us VVL-ers.Between this header and the new hybrid cam work going on,we are making leaps and bounds here to eat more v-tec!


X2 Thats an understatement!!!!

The last header pictured is the production budget header with full merge collectors. I am going to send the header for 3rd party testing this week and maybe they can test it this weekend or next week.

I am STILL waiting for the flanges to come in. I'm not sure whats taking for ever but thats the hold up at this point.

Ha ha... this is O/T but when we had our VE dyno day we held 4 places open for the NZ Honda peeps to come along so we could compare our VVL with their VTEC. We like the Honda Club & there is a bit of friendly rivalry between us which is always good fun. There was some smack talked but not one NA Honda showed up. A couple of guys did flash dyno sheets from another dyno on their forum that made it look like we were toast... numbers around 150wkw which we haven't hit yet & is a bit of a magic number for us.

Anyway, one of their members did turn up in a Toyota that had made 145wkw on the other dyno. Amdeman goes & gets 139.9, then I go & get 138.9 & then this Toyota goes on.... 118wkw! He was a really nice guy & I felt sorry for him but it did prove the point about same dyno same day!

One of their guys had posted a 150wkw dyno sheet with the statement 'Beat this Primera pussies!'

I wish that car had shown up...

^^^ ha ha ha too true, i have learnt to take dyno numbers with a grain of salt over the years. we a bit fluxuation as well, i wonder if it is as bad in the u.s.

I've dyno'd my basically bone stock 06 RSX-S at about 5-6 dyno's around the area, even one 3 hours away. The dynojets all read within about 2-3 hp. I have also checked on 2 dyna packs. One a 4000 the other a 3000. The 3000 they said was calculated to read the same as a dynojet, and it actualy was about 1% low consistently. The other dynopack 4000 was about 6% high consistently. This one was not recalibrated to read on par with dynojets though.

All this was done in SAE to actually compare these to one another becasue a lot of people bitch that the dyno that I use ( Intec Racing) reads higher than any other dyno out there, In reality, that dyno had the lowest readout of all the dyno's I checked ( other than the dynapak 4000). I did check a dyno dynamics about an hr a way and it read about 7-8% high, but that was at a different time before I did all this other testing.

People wouldn't believe the kind of manipulation dyno operators can (and will) do to control the numbers coming out of their shop. SAE correction, if I understand it correctly, when applied, should force the dyno to spit out numbers that can be compared to others, and that actually mean something.

Last dyno I went to they left the air temp sensor out in open air claiming that the numbers were inflated when it was put near the air filter (no shіt), and further inflated if they put it by the exhaust manifold (doubly no shіt). That's the way the device was designed. Just because you don't like the numbers it puts out, doesn't mean you mess with the equipment until you're happy. Those air temps are needed for the correction calculations.
Sorry for the rant.

The place I was talking about had a Dyno Dynamics. It read 25% too low (because they failed to probe the air temps properly). We have a local Mustang dyno that knows how to run it properly and thank God we can go there.

The Dyno jet I use to dyno reads about 5hp lower than the Dyno pack that I dynoed on a few years ago and both were SAE. I just use 1 dyno all the time to see any gain or loss in what I do.

let's all not forget why we are here....

Where's mah heada!!!!! lol


On another note actual hp/tq is great to know for your own personal edification. Actual hp/tq is what will get you down the track with solid numbers. I wouldn't be surprised if some people do make 220whp actual and get down the track showing their cars are making that power.

But if you want to compare across the country and across the world you have to convert to something that makes sense to everyone. I like using the intec dyno because so many other cars have dynoed there and I can compare my SAE to theirs. I have yet to see anyone else show an SAE corrected dyno for a VE making 210whp+. The only car that has made those numbers had an ASP header on it.

once my income tax check comes im grabbing one of these bad boys.

n1's, this header, and some higher compression pistons and your putting down 220whp easyyy.

stratton.
