Great job Dandy. Awesome numbers.

 

Same as yours(I think)
My cams for my n/a motor=260/260 duration 10.9 lift.
Jwt doesnt recommend going above 7200rpms
My "former" machinest suggested no more than 7500 with the: jwt springs, arp rod bolts, & stock oil pump.
So im still thinking about reving to 7500 with a jwt ecu.

I read the graph... Its seems as though I will be better off with the Vq35HR dbl shim next build. Thankyou.

 

With the stock oil pump I wouldn't go over 7200

 

OMG!!!!!! I'm getting even more anxious!!!!!!

 

^^^ Kevin, are you buying his motor?

Dan, that is very impressive. Are you planning to beat this at the track, or take it out, sell it, and then drop in the 3.5?

I'm curious, what's your next project after the Maxima? Have you been thinking of that?

Also, which tracks are you hitting this year, if you haven't started? I saved my light rims for Cayuga, but if I sell them, I'll be keeping the I30 as a daily driver, and picking up something smaller and lighter for the track.

 

Another thing I might do is switch to the HR retainers as well...

I think the stock oil pump might be ok at 7500, as long as you have the stock crank pulley on there (ie damped), but I can't be certain. SR20DEN was revving up there for a long time and IIRC he didn't even have a stock pulley, but I could be wrong, I'm not 100% sure.

 

The DEK is VERY close to coming out of the car. There's a chance I *may* hit the track once more to chase a 12.5x but only if a friend of mine ends up going in the next couple weeks. I definitely want to have the DEK out of the car by about the end of the month (or sooner even), otherwise the 3.5 project will get delayed, there's a lot of work left on that yet besides actually just putting the engine in, and I've gone just about as far as I care to with the 3L. Time to move on to bigger/better...

Next project after the Maxima will be a RWD setup. I haven't decided for sure on the platform yet but there are a few I'm considering. In any case that's still a few years off.

 

So, you were optimally 'tuned' for the atmospheric conditions?

But you're auto... aren't you?

 

Yes I was. Probably spent the better part of 2 hrs tuning on the dyno. I also have an air temperature map that corrects for varying conditions such that my AFR doesn't stray all over the place.

 

Wow... I'm late on this, but those are awesome numbers.

Maybe I should do a DE-K swap into my 2002? It'll save me some oil in the long run

 

Is this incorporated into your EU 'tuning'?

 

Um... why the quotes around tuning? Yes it's all done in the EU...

 

Because I don’t like to use the word so loosely. But, in your case, and definitely in your case, it IS tuning. Habit.

 

Congrat Dandy, your pulling some very very nice numbers, I think with a P & P jobs on the LIM - UIM - Heads you would probably hit the 300 hp.

 

Hmm, dunno... but I'm not putting any more work into it now, not worth it to me as the 3.5 awaits. The heads were not ported but I did do some bowl and surface finish work throughout, casting cleanup, etc and the openings (heads to LIM to UIM) are all well matched also.

 

Check out the spec on the stock 3.0L heads versus the same P & P:

Stock P & P
Intake port width: 55.35 mm 57.50 mm
Intake port hight: 32 mm 34.50 mm
Exhaust port width: 44.65 mm 49.50 mm

My vernier caliper was calibered just before taking measurement.

On the intake port I couldn't shaved as much material as I wanted, I was limited by the LIM's ports width, it's pretty much the maximum I could shaved.

The inside of the ports are also much wider than they where originally, those heads will defenitely flow much better, but that's all theory until we dyno'd.

 

Well there is a lot more to porting than just hogging out/opening the whole passage up, sometimes that's actually counterproductive (as I think I've mentioned before).

But anyways, I'll look forward to seeing your results, I hope it turns out well for you. Any idea when you'll be ready to dyno your engine?

 

Dude you are the man.

 

Huge +1.


In some cases even ADDING material in certain spots can be beneficial. It's all about velocity, even at high RPM.

 

That is some great power, keep up the good work cant wait to see what your 3.5 comes out making

 

I took the week off to rest & finish the P&P, so hopefully by early next week I'll drop the heads at the machine shop so they can do the valve jobs. The machine shop will probably do the heads within a month, then I should be able to re-assemble the engine by July-August, after what I'll have to send the engine for reciprocating > I found a local reputable shop to balance the entire engine once the assembling is done.

Congrats again on those great numbers.

 

Specially near the valve bore, the air flow doesn't like 90 degree angle but I'll ask the machine shop to flow bench the heads and see the result.

 

Simply awesome. Expect a lot of traffic from this, .org guys know their VQ's.

 

I don't get it...

Cams = 40whp?????

Wow.

 

How did you do your math? Dandy has way more than cams, as we should all know if we're posting in here.

 

Never mind that... I wasn't thinking...

Question though, how do you get 3.5 cams in a 3.0? You have to use those adapters???

 

yes you have to have adapters so that you can use the 3L timing parts

 

.. or something that does the same thing. I didn't get adapters, I had my sprockets machined and spacers made...

look here for a pic of what I mean

 

Dandy those are some serious numbers. I will be happy to see that number on my 7lbs of boost, that is awesome. Now i can rub it in my friends K20 RSX that the VQ30 has some potential too with the right person behind the build. NICE!!

 

This DE-K isn't a "built" motor.

 

i really hope my eu can do half of what u did with urs. those are impressive numbers, they deff inspire me to get my car up and running

all u powerful 4, 4.5, and 5.5 gens are out there kickin a$$ we need more 5.0s im working on doing my part. hopefully 250whp at one point

 

Holy Crap Dandy thats crazy!!!

Its funny. Your HP numbers are putting some of these VQ35 guys to shame. If only the VQ30 made the torque the 3.5 made of.

Its going to be nice to see what your capable of making with a VQ35 properly tuned and driven.

Way to go man, huge props!!!

 

I second this motion down to the teeth. amazing #s!

 

i'm definatly excited what you can do with the 3.5!!

great numbers!

 

Sweet numbers Dandy!!


I am glad the budget shim/spring idea worked out.

 

Seems like I haven't seen you in ages on here

 

Yeah that was a key part of it for sure. If not for the oil pump I could have gone to 8000 easily, maybe 8200. Thanks again for doing the spring pressure testing, that started my wheels turning when I saw I actually had some numbers to compare.

 

wow amazing results!
congratz man!!!
