My other vehicle in my garage makes 200hp/liter

What's the definition of a "way better engine"???

PS - It's not really about the "way better engines" that make over 100hp/liter. It's simply about modifying the motor to rev to 8000 and breath well at that rpm to make power with the same displacement.

 

wow, you have a formula 1 engine? 200hp/liter naturally aspirated? i'd be curious to know what car it is!

we are talking NA here, not even race cars reach 200hp/liter naturally aspirated.

By way better engines I talk about engines who already have what has been mentioned stock, ITBs, high compression pistons, 5 valves per cylinder, hand crafted, engineered to rev to 9000rpm... etc.... top of the line BMW engines, Ferrari Engines, Porsche engines. All produce between 105-120 hp/liter NA, and that's about as much as you will ever reach on street car with this dissplacement.

 

It's not a car...it's my Yamaha R6, 4 cylinders, carb'd, 600cc (.6L), 12.5:1 compression, 120hp (actually a little more since I have exhaust and rejetted the carbs)

It doesn't have 5 valve's per cylinder or variable valve-timing, hell it doesn't even have fuel injection and it has 200hp/liter. My point is you don't need all that high tech stuff that they use on Ferrari's, BMWs etc. to make power with low displacement. All you need is a well engineered motor (the VQ DEFINITELY is), high compression, and breathing ability (intake manifold, cams, headwork, exhaust) at high RPMs.

Look at Honda motors...I've seen B18's (1.8L) put down 220-230whp N/A. That's between 120-130hp/liter.

 

dude, I said "you will never reach on street car with this dissplacement".

2cc monocylinder engines in RC cars produce 1000hp/liter, that's irrelevant.

3.5L is not low dissplacement, and you will not get 120hp/liter out of it. If you do, it will not be reliable, not be driveable and will cost so much money it would be nonesense.

 

RC car motors are NOTHING like the motors in cars and can't be compared. Plus they run on completely different fuels, and are air-cooled 2-strokes. That's like comparing an ant's strength to a human's. The FOUR CYLINDER, FOUR STROKE, WATER COOLED MOTOR in my bike uses the same basic design and principles to make power that the motor in the 350Z does and is only 1 liter smaller than a honda B16.

I never said 120hp/liter although the full race VQ35 used in JGTC racing makes over 400hp.

I'm was simply trying to say that 350whp is attainable in a streetable 350Z, and that you don't need individual throttle bodies, and 5 valves per cylinder to do it.

BTW - you quoted yourself as saying: "you will never reach on street car with this dissplacement". I can't find where you said this or anything remotely close to it previous to that post.

 

The e46 M3 can make 420hp with NA mods.

 

What kind of dyno was this, dyna pack, dyno jet....etc?

I have the 1/2" spacers sitting in my room right now and I will be doing a after dyno with them installed.....do you guys think I will see any gains with my 05?

 

Dynojet.

 

I have 262 whp and I trapped 106 consistently last time out, I even trapped 107 on 1 run Id like to see this guys trap speeds when/if he goes to the track. That VTC sure must help, cuz you sure got great gains from it. Seems like all the people around Crawford in TN see great gains.....BTW I own a Crawford plenum so Im not hating, just stating my observations on some Crawford plenum dyno's Ive seen.

 

full race VQ engine in JGTC 300 produce 300 hp, as the rules limits them to 300hp
full race VQ engine in JGTC 500 produce 500hp, but are turbocharged and are derived from JDM VQ30DET

I missquoted myself, but the meaning is the same. I was replying to your 200hp/liter car fantasy. "105-120hp is about as much as you will ever reach on street car with this dissplacement(3+ liters)."

and I will be EXTREMELY surprised if someone brakes 105hp/liter with the VQ35DE on a street driven car. VTC or not

we only have 1 dyno, from 1 car and now suddenly 400+ crank hp is feasable.

 

We are saying 400hp is feesable with big cams, higher compression, all boltons, and maybe ITBs. The 400hp mark would be reached depending on how much power the higher compression and ITBs give.

 

Regardless of what power the JGTC cars make (I thought I read a while back that they had an N/A VQ35 that had 400hp.) That was a side point.

You miss-quoted yourself and now you've miss-quoted me. NEVER did I say that any street car would go and make anywhere near 200hp/liter. If you could quote me saying that...I'd be very impressed. What I was simply trying to illustrate, which you COMPLETELY missed, was that a motor doesn't need all that high tech junk to make a high hp/liter number.

As for you...you say the most that we'll ever see on a 3+ liter motor is 105-120hp/liter. Well 105hp/liter on a VQ35 puts it at 367hp and 120hp/liter puts it at 420hp/liter. So you pretty much AGREED with what I said. I said that 350whp is attainable on a VQ35 normally aspirated....and that's between 105 and 120hp/liter, which you deemed was "as much as you will ever reach in a street car with this displacement"

 

shut the F up, please

I said the best ~3L NA engines in the world produce between 105-120, I wasn't speaking about the VQ... I said I would be surprised if the VQ can reach 105... YES you needs high-tech, advanced materials, and lot's of engineering to rev to 8000rpm+ and produce power up to there on a street car. If it didn't require all of the above, an M3 would cost 30K and the 350z would produce 350hp stock.

Why you brought the 200hp/liter motorcycle engines in the discussion remains a mystery... anyway, send me a PM when you get the engine to breathe well at 8000rpm and you reach 400hp

 

Don't tell me to shut the F up. I have as much right to post on here (assuming I abide by the rules) as you do. Doing so makes you look childish and immature.

There are 3L VQ's over at Maxima.org that are revving to 8 grand AND MAKING POWER up there...on the STOCK VALVETRAIN. All they have is an intake manifold swap and an ecu flash for a higher rev limiter. I have a video of one somewhere. Look at to old FORD TAURUS SHO. My buddy has a freaking 89 than makes 280whp @ 8200rpms N/A and rev limits @ 8500rpms. That's just an OLD 3.0L V6...

FOR THE LAST TIME...I BROUGHT THE MOTORCYCLE ENGINE INTO THE DISCUSSION TO SHOW THAT YOU DON'T NEED ITBS, 5 VALVES PER CYLINDER, VARIABLE VALVE TIMING ETC. TO MAKE HIGH RPM POWER. My motorcycle engine shares a lot more in common with a car engine than you seem to want to realize.

Is that better or do I have to translate it to Spanish, German, French, and Japanese for you to understand WTF I am saying????????

 

It's kind of hard to not tell you to shut the **** up when you know EVERYTHING. I mean, it must be cool to know everything about everything.

 

Best argument evAr...just tell the other guy he thinks he knows everything (which he obviously does not) and it will just make you look better. Cute...but overused and played out.

In other news...you obviously know more than I do since you seem to be able to GUARANTEE that you will run better than 13.3 with a few bolt-ons in your auto Z. I didn't know you could see into the future!!!! Can you teach me to look into the future too??

Now you just look dumb. If you have a problem with me, PM me instead of sitting here and polluting ANOTHER thread with nonsense.

 

Thanks for hijacking this thread. At least it started out NOT SUCKING.

 

Wonder what will happen on the flip side if one was to attach a 04 plenum to the new 05??

 

putting a 04 plenum on an 05 track would be interesting. you will probably notice a good increase in torque, and maybe power down low, but the higher rpm would suck i think..... it'd be fun to see a dyno tho...

 

thats what I was thinking, perhaps one could recover TQ lost in the 05 engine at a low sacrafice to HP. And perhaps even a run with a spacer. to see how that works...
