AGP L2R

[rubbersidedown]

start a new thread possibly?

 

[UndergroundR32]

No, my discussion with jdmawd is over. Sorry to get off subject rubber.

 

[rubbersidedown]

its cool. there weren't many posts that were on the subject anyway.

I have a serious question for you. Would you say that the major advantage of the L2R other then efficiency and flow. is spool between shifts? I was under the assumption that initial spool would be a tad quicker than my 50?

It could spool quicker. But, in my case, probly a bit slower. Im getting full spool by about 3700-3800. But yes, the main advantage is instant spool between shifts. My boost guage looks like a switch. When I get off, it goes vacuum, when I get back on it shoots right back up to 20psi. Absolutely no lag.

 

[larryd]

yeah same here.. the boost response above like 3800 and between shifts is pretty much instant.

I just want to get the turbo to spool a few 100rpms sooner, I was used to that big28 hitting full boost at 3200

 

[rubbersidedown]

what could be done to make the turbo spool faster? different cams? high compression pistons? what're my options?

 

[larryd]

higher compression should do some..

cams could go either way I suppose, they could have a positive or negative effect on spool.

nitrous is always an option if your die hard

 

[rubbersidedown]

nitrous? well if i'm just looking to spool faster then do you think i could get away w/ just using something small like a 50 shot?

 

[larryd]

i honestly think something as small as a 35 shot would have this turbo spooling around 3000rpms.

 

[rubbersidedown]

well damn. i'm there. but then my next question i guess is... if i'm just using a a lil 35 shot then could i still run stock pistons or maybe a set of '95 pistons? i'm a little apprehensive about getting aftermarket forged pistons after hearing about how they slap around in the cyclinder or whatever.

 

[rubbersidedown]

oh, and on a side note... is there an engine block heater available for the engine? I noticed that its an option on a lot of newer cars. I hate having to wait for my car to warm up in the morning.

-edit-
and one more thing would getting the T04B or T04E compressor housing make a difference in spool time?

 

[larryd]

i dont know to much about the effects of nitrous and pistons but I know when I was planning on running nitrous and the turbo I was going to do a forged internal setup. you might want to ask that question specifically in the nitrous forum on here..

and no clue about the block heater..id like to know myself since i hate letting the car warm up as well.

Timing advance has a lot to do with how quick your turbo spools. If you have the adjustability, you may want to bump the timing at 3000-3500. This is part of the reason the 1g's spool big turbos a little better than 2g's. For the most part 1g's usually run more advance. Or course, fuel tuning is important too.

As for forged pistons, if you get Wiseco's you don't have a lot of these problems. I just built a 4g64 with them a month or so ago that purrs like stock even when cold.

[larryd]

hmm.. well maybe thats why my spool isnt so good then, becuase my timing is horrible

The problem with this thinking is that it would cost you a small fortune to keep the bottle open all the time. 40-60 for a refill and they can last 20 or so passes it starts to get expensive quick. I will agree that the 4g64 looks like it will work out very well. But then again I am a little biased I have one sitting on the engine stand.

Its amazing how few people in this thread know the difference between spool, lag, and boost threshold. They are not interchangeable.

For instance, on my current turbo (not an L2R), my boost threshold is about 2600 rpm's, the spool is about 4-600 rpms as I get full 21psi by 3000~3200 (gear dependent) and the lag inbetween shifts is almost nil. <300 rpm.

 

[Thalomos]

I've been looking at the L2R a while now, and everyone talks about how it's god etc, but i see all these cars, running times that a 20G can run... so i'm sceptical for now, but i'll keep my eye out.

thats true get the 20, i know glazer ran 11 flats on it. i think its a better choice than a gt30 hybrid

 

[GalantVR41062]

why would you ever want full boost by 3000rpm(not RPM's its not plural people) in a dsm with the L2R that would hit hard and probable cause traction issues in unideal conditions, I say the L3R with full boost by 4300 is great you dont go boosting around like a rice man with his blow off valve noise making device and when you get on it be in the right gear you dont go trying to race the vet from a 3000rpm start in 4th or somthing you use 3rd or 2nd come on people. My mutt 1 did not got full boost until 4800rpm on the dyno, now that was a little to lagy, for the no HP it never provided, but that was due to low compression and many many vac leaks. and as for N2o the fastest GVR4 has the stock 140,000 mile short block and a 54 trim turbo with a shot of N2o running
10.9 @129 so the stock 6 bolt will take a lot of abuse, so put the L2r on a stock 1g motor turn it up and run N2o if its not fast enough.

if you dont want "turbo lag" go buy a V-8 and use your Low end torqe to pull on them form 1500rpm idiots.

 

[BrnOutKing]

I've heard but don't quote me - FP is actually making a new turbo using the GT30 wheel?

they thought the AGP turbo's were so good they thought they'd create there own.... as they didn't like the 7cm housing. thought it would be to constrictive?

Any truth to this rumor?

I am glad somebody has brought this up!

It has been bothering me that so many people talk about spool rpm and dont say at what gear as well. My T-25 will get full boost at 2800 rpm in 1st but in 3rd it will get full boost at about 2300 rpm. Lets be specific when we are talking about spool time. I just wanted to clearify your post tell me if this is wrong.

1. Boost threshold: Does this mean where you get positive intake pressure. So your boost gauge reads 0 psi at 2600 rpm in 1st gear?

2. Spool: I think you mean at what rpm you get full boost. Boost threshold rpm + spool rpm = full boost rpm. Say 2600 rpm + 500 rpm = 3100 rpm at 21 psi. Right?

3. Lag: How many rpm you need to run through to get full boost back between shifts?

 

[jdmawd]

1st gear 20 psi 3600 from a dead stop

 

[Thalomos]

Wow, so the L2R spools "super duper quick y0!" and gets "Instand boost between shifts mad quick tyte style y0!"

But what does all this matter if your still slow?

Just my observation

Slow is such a subject term. So is fast. Use numbers. How long has the Green been out? How many of sold? How long has the L2R been out? How many of Sold? What about the Mutts?

Where does everyone get this attitude of 'it's gotta break records right out of the box' crap? It's still all tuning for christ sake. Get it in a few more respectable tuners hands and then make your judgements. I find it hilarious how many 'band wagoners' jump on when something knew comes out. The Green is the king of the hill right now so everyone is 'pro-green'. If/When the L2R or L3R starts throwing numbers that they should around, those same 'band wagoners' will be first in line to kiss a$$ at AGP and get one for themselves.

It all boils down to this. Buy the turbo you want from the company you trust that meets your needs. We know what the Green/Red is capable. Its a well known. Give the AGP turbos a chance and I think you will see the same thing. I am still waiting on the numbers from the Mutts.

I am not talking up or ragging any specific vendor. I just think all this 'clique'y crap is getting old fast.

that could be true, for any turbo. right captain obvious
