I am wanting to know from actual users, what the off boost throttle feels like doesnt matter if you have a lighter flywheel, modified head etc, how does vacuum feel as far as response, and power with your low compression b16. any regrets? ?

 

im running 8.5:1 comp any it feels pretty good and the car is strictly track

 

I don't think you will find many people running less then 8.5; I am running the wiseco's which are 9.0 down from the 10.5ish(layer removed from HG) that my SiR2 b16 had before. I cannot tell the difference at all.

 

up

 

for me 8.5 drop was a pretty big thing...but i guess it depends on ur turbo sizing etc.

 

I dont see the point of running lower than 9:1 anymore. we have the tuning tools to be able to boost at higher compression anyways and it will have less lag no matter what turbo you are using.
we mostly do in the range of 9-10:1 but 10.5-11:1 compression turbo setups is common as well.

 

I was at 7.8:1 on my B16. Saying low compression has more lag is a steaming load of crap, because I couldn't notice any difference. It was fun pushing 25 pounds of boost on 93 octane.

(11:1+ boost here). NO reason for anything less than 9:1 IMO, as well

what a turbo needs to spool=exhaust gas

higher compression=more exhaust gas at any given rpm

That has already been talked about on this board that doesn't mean a thing.

Lets see, he did a REAL test vs. some random crap people on the board think.

That's Real Information - 1 Stupid, wrong assumptions - 0

Even if compression did make some minute difference in spool, that difference is made up for with the whopping increase of 1.35 cubic inches due to the .5mm overbore. Yeah, i'd say compression plays a HUGE factor in turbo spool.

 

damn what did the 5 fingers say to tha face!

That is all you can go off of, do you know what pushes a turbine wheel and dont just name the gasses. Then think about how compression affects it.

Every thing matters.

He had to increase the ignition timing and the engine has lost 15whp .

There a flipping difference, not to mention its less efficient.

Yes, the motor lost 15 WHP and he had to add timing. That's because he dropped the compression, tell me what this has to do with comparing how a low compression motor spools a turbo? If I have low compression am I going to add a few degrees more timing back into the motor, or should I just leave the timing where it was at on the high compression motor and suffer? Yeah, that makes a bunch of sense. Ooh, I have a good one. If you can only launch at 4000 RPM's on street tires, you should only launch your car at 4000 RPM's if you bolt a set of 24.5" slicks on it, right? Want to keep everything fair and all. Don't make use of the advantages you get from anything, no way, that would be just too unfair.

I see so your inexperienced.

Ignore this guy he has no room to talk, just going off of a somebody elses simple comparison.

 

i have an 8.5:1 B16 and i always see all these guys making all this crazy power at like 10-14psi, i am currently running mine @ 18psi, and i achieve the numbers they do but i always wondered what a 9.0-9.5:1 would be like

Yeah, I'm so inexperienced. 6 months ago you didn't know how to file down a god damn piston ring, so go ahead and say i'm inexperienced. It's a bull **** way to try and end an argument because you have absolutely dick on your side to argue with. So, to summarize

-Boosted hybrid posts small power loss from 10:1 to 9:1 compression
-You say that doesn't compare spool at all because he had to add timing.
-I say you're wrong and that argument has no validity
-You say i'm "inexperienced" so people shouldn't listen to me

Your argument with no facts or anything to support it is bulletproof

Go look at boosted hybrid's comparison. 14 WHP at peak on a 300 WHP setup going from 9:1 to 10:1. Going from 8.5:1 to 9.5:1 would give you roughly the same change in power. If you're taking 8 pounds more boost to make the same power as a guy running 9:1 or 9.5:1 compression, or even 10:1 compression it isn't just because of the compression. Weather, correction factors, THE TUNE, etc, all play a big role in how much power you make.

 

If you look at the boosted-hybrid graph, you'll notice what I see. If the 9:1 setup was given more boost (which it can take, not *just* because it's forged), it would mirror the other graph, since it would make more HP, but it would take that much longer to reach full boost. Low CR spools sooner *at the same rpm*, but makes less power at that psi. Adding boost won't change the part of the graph before the turbo spools up fully.

The other thing is that forged internals can be made lighter since they're stronger. I'm interested as to the weights of both 10:1 and 9:1 setups. Seeing as how most high CR boosted motors don't seem to be posting problems with busted internals, I don't see how anyone can make a valid statement out of 'higher CR = less milage'. To each his own.

Recap:
-lower CR does NOT make more HP before turbo is at max boost
-lower CR allows for more max boost
-lower CR spools faster *at same psi level*, more boost means longer spool time
-lower CR doesn't mean safer when the tools are availible to make a perfect A:F

So what if I asked how to file down a piston ring was I suppose go scrub on it not knowing how or do that smart thing and wait for the best FI guru tell me what to use...

and so for the spicy question!

Did you win a prize for looking thru my thread list?

Keep running your mouth till you go try it yourself idiot, you yourself have nothing just a cocky *** mouth till then sit down and shut the **** up.

Hi profile

He also says that no boost controller was use and there was a restritive *** ITR muffler on there.

But at 18psi isnt your tq alot higher than these people at 10psi?

I have a cocky *** mouth, but you're the one that says his comparison is worthless for some completely nonexistant reason, and you couldn't even put a motor together as of 8 months ago, and probably couldn't put one together now. I've done it myself, rebuilt several motors, and that's more than you can say. You're right, i'm an idiot and have done nothing, lol. Want to go ask people how they made 3-4" reducers with their bare hands, that's a fresh post showing how brilliant your automotive knowledge is. And what, dare I ask, does having no boost controller and an ITR wastegate have to do with comparing the difference in spool due to compression? They're controlled variables, they were the same on each test, and have absolutely no relation to the test. I could swear we learned that in grade 6 science class, didn't we?

If you wish to continue trying to stroke your ego by replying to this thread, go right ahead, because I'm not going to. Enjoy!

 

I'll just ignore these 2, you can clearly see how hard they try to make someone look bad, I dont want to ruin your thread boostage.

One infers ITR have wastes gates or maybe I was talking about a waste gate when I'm clearly saying muffler.

While both try to go in my history to make ''fun'' of me. I'll just ignore these guys aren't worth it.

 

instead of bickering back to them with pointless posts why dont you try and defend your point? cause it dosen't look like you can...

I'm not trying to thread jack here against H-T rules, its also going OT, and this isn't my thread.
