Resistant for how long? What content of ethyl-alcohol is their treatment good for in saturation? It'll be interesting to see, as Methanol is much more corrosive than even Ethanol.

Cabletie

The guy said that some racing teams here are using it with e85. It is resistent to 100% ethanol btw but he doesn't know about meth. I think I'll send him a little quantity for a test

Excellent suggestion.

Hey italiano.What water injection system you used?

Cabletie

Balor_Gr

Mate im dying to see how managed to do boost by gear without avcr !!!


Im thinking of getting water injections but imo the "spray by boost psi" is kinda strange.
Id like to find out if there is a kt that knows my exact rpm in combination with boost.
Because if the pump pushes max at lets say 10 psi our cars have 10 psi from 3000rpm to the red line.
So for as you raise rpm you gain less and less water per combustion right?
I may be wrong because i dont know **** about water/meth injection but that what my brain tells me.

Cabletie

I see your point, but you have to choose the right jet size for your application and then use the nitrous tables (if you have hondata). In this way you can have a secondary table that will control ignition advance based on rpm, and fuel as well! especially with the fuel table you can control what you are describing. As long if you do not detect detonation you are good with the jet. ( in my case with the intermediate jet I see 1 piont of AFR more. Then I control that with the secondary table that will take out fuel and leave out more room for water/meth)
I don't know if my sentence is good! let me know if you understand me LOL

What is AVCR?

AVC-R is one of the first electronic boost controllers that utilized parameters for boost-by-gear & boost-by-speed. Most people around here didn't use them because of their expense and for some, its complication.


I used to use the boost-by-rpm feature:


Here's the boost-by-gear portion of it.



I had one of the 1st versions back in 1998


I now use the GReddy Profec

Quick update! The engine is still running strong ! now at 12 psi with water meth. There are two main problems tho.

1- During these hot days the "abarth radiator" seems not helping. I bought a 3 row gpi radiator that I have still to install. I'm thinking about removing the "abarth radiator" because it actually obstruct air flow to the half size radiator. What do you guys think about it?

2- The manifold has cracked. I welded it but it continues. It cracks on the merge, so not on my welds, and this is the only positive thing about it. Now It has an inner diamter of 42mm. I'm thinking about making a new one from zero. In your opinion an inner diameter of 45mm would be too much? I'm planning on 316L instead of 304 stainless steel.

TheShodan

I think 45mm is unnecessary for that size of a turbocharger. The Equal Length manifolds that are so popular on many of these builds are really overkill for smaller turbo'd B16s and they run 45mm sized inner diameter stuff as well. I simply suggest sticking to the 38mm and use better materials with shorter runner lengths where ever possible.

Cabletie

I agree with you, but won't they help with more aggressive cams and high rpm?

For the cooling system any suggestion?

[QUOTE=Cabletie;51341358]I agree with you, but won't they help with more aggressive cams and high rpm?

No. Not unless you're changing turbochargers. You're a B16 using exhaust pulses of a small displacment engine with a turbocharger at about 38lbs/min or so. It won't help in the way you think. It will take a lot of the characteristics that you like from the MHI unit and basically throw it all out of the window.

Hard to give suggestions until we know more about your new exhaust manifold configuration. If you're talking companies, Koyo, Fluidyne, and C&R come to mind the most. As for half-sized vs. Full-sized, I still say Koyo, but again, we gotta see what you're proposing for an new exhaust manifold.

wow havent seen those avcr screens in a long time!

TheShodan

They're still being used quite a bit outside of the U.S. ('Cuz 'Murica & Drag Racing) in which laptop-based control doesn't really do the job on the circuit or street when it comes to changing boost pressure levels quickly.

Balor_Gr

Im wondering what other bc if any have boost by gear as a standalone lke avcr.
By the way avcr is VERY good.I still cant understand why pretty much noone used it in the states.

TheShodan

iTrader: (14)

I stated the reason above... Americans want simple and popular, because they are devoted to drag racing in a way that this controller makes it ....uncomfortable for most of them to use.

Balor_Gr

Well its super famous here.Its actually the most common thing on high hp cars.
​​​Like "everyone above 400 has one" common.
Did you mange to find anything newer with boost by gear?

TheShodan

iTrader: (14)

I completely understand. In Europe the AVC-R and Profec are the common one used.

The only standalone boost controllers that use Boost by Gear is the AMS1000, and at over $1000USD, may be a bit on the overkill side.

The HKS EVC6 2.4 has boost-by-speed that was very easy to manipulate compared to the AVC-R. But again, not Boost-by-gear, again because of the fact that although drag racing has grown globally, the need for that particular feature is really only limited to those in the U.S., that don't mind using a laptop to work with the rest of their system. It's just a different kind of thinking for a different kind of racing.

Evc is interesting.I only knew it had boost by rpm.
I research further about it.

Hi guys! bought some elbows 304L 48mm outside diameter and 42ID. So 3mm thickness for my manifold. The design should remain the same, and I'll hope it will not crack anymore!
Moreover finally I made an agreement with CSS and My new block has arrived! I'm so happy about that! Planning on upgrade my 16g for the build block!
By now I'm at 14 psi with stock block I think I passed the 300hp line since my dyno was 289hp at 10.7 psi

oh and I almost forgot that the new gpi 3 row radiator is awesome! cheaper and better that the mishimoto! no more coolant temps problems

Balor_Gr

My friend how was shipping and generaly the order from css im thinking of getting one shipped to greece for quite some time.

TheShodan

iTrader: (14)

Get a sleeved block done and have it shipped to Greece if going through all that. Don't go through all that trouble with import fees, customs documents & manifests, etc, just for some custom machined block guard.. excuse me. "Support System".

Spend your money one time, smartly. "Buy Once, Cry Once."

Cabletie

awesome costumer service! I bought one block directly from them and with shipping was 700$.

tony_2018

I like that quote

Cabletie

Some news here guys! done new manifold sch10 1.5" .













with big surprise, spool has not changed and the top end seems stronger even with stock cams so I'm pretty happy!

Also I bought a turbotechnics for a ridiculous price that will go on the css block
