My setup is Hondata, 550cc injectors, I/H/E.
Would it run safely@9psi w/o internal mod(forged pistons, rods)?
Should I go for 9 psi or stay with 6 psi?

Thanks!

 

nope... at 9psi you will see over 200 deg intake temps..... way to high for my taste

What if I get Hondata IM gasket, will it help on reducing the intake temp?

 

Stock H22's shouldn't run more then 7-8 lbs. daily. I am going to run 6.5 lbs. on a T3/TO4E. I think you would be doing a little more then pushing it considering you don't have an aftercooler.

the intake temps are created from the air being pressureized, not transfer from the engine....

 

You will be fine, sounds like a fun set up.

About the IM Gasket, it cant hurt, took my intake temps down over 30 degrees w/ the Jackson.

JDogg, thanks for your suggestion.
So is there any other way to help on reducing the intake temps? like intercooler?
I think I will stay with 6 psi now since the intake temp over 200 is damn too high.
Do I really need Hondata IM gasket for 6 psi setup?

 

if the charger is off or you havent put it on yet get one, otherwise its too much of a pita to install one with the charger already on.

you should be able to make about 230-240hp with 6psi tuned properly

 

aftercooler

JDogg, for 6 psi, what's the A/F ratio you suggest? 12:1 is ok?

id run it 11-1 or 11.5-1... you wont pick up any power going any leaner so run it rich to help save the motor.

 

Why won't he make any more power running it leaner than 11-11.5? Just curious.

 

cause the intake temps are so hot.... if you ran race gas you could run it leaner and get some more power.

The main purpose of fuel (aside from the fire aspect) is to cool the intake charge. The increase in power by going leaner isn't worth the additional heat generated in the long run.

FYI, I found that my "b" series jrsc loved an A/F ratio of 12/12.5:1
EGT's were respectable, and in a day or two I'll post some pics on how the internals liked it.

A/F 11-1 or 11.5-1 is for 6psi or 9psi?
currently, I'm running 12-1~12.3-1.

 

the last one i tuned was at 9psi and the egts were nuts even at 11:1

at 6psi i would not go leaner than 12:1.. there isnt enough power picked up to be worth the risk

 

I've run 10 psi on my D16Y8 with stock internals for over 2 years. If you have a good standalone and proper tuning it will work fine and last if not abused. Get yourself a good anti-det electronics (J&S) and it's even better. Keep in mind the stock D16Y8 motor as 9.6:1 compression and the H22 has higher then that. I can't remember the exact compression ratio of your motor, but if it's pushing 10.25 I wouldn't go past 8 psi. On a side note, read up on this site http://www.lhtperformance.net/ They make intercoolers for the JRs. Mostly D and B series ones, but I'm sure they can make one for the H22... I think John was working on a few protos already for the Preludes.

 

h22 chargers heat up the air alot more than on the smaller motors, they flow more air b/c of the bigger engine but with the same size charger....

 

JDogg,
If I get over 900c EGT, will detonation occur or its case by case?
I dont have EGT gauge but I'm sure no detonation occured,
so i'm worried if EGT is too high.
What's the relationship between EGT and detonation?

Umm, last time I checked the H22 charger was the M62 and not the M45 like mine is. No offence, but get your facts streight. An M62 blower at 10 psi will put out less heat then my M45 at the same level. You don't have to spin the 62 as fast to create the 10 psi as you would on the 45.

 

m62 is the same blower they use for the gsr/itr chargers

 

Who has the forge pistons and rod with JRSC setup?
I'm considering to get internal done then go with 9lbs boost.

 

There are SEVERAL people running 9 psi JRSC ludes with Hondata on stock engines. Get a GOOD, EXPERIENCED Hondata tuner and you will be fine. 12:1 a/f should be fine.

And you call yourself a tuner?!?


What sort of timing curve were you running to get these "nuts" egt's? Ever consider that maybe the fuel is burning in the pipe, and not the combustion chamber?

What about cam timing? Were you running a fat overlap, once again, burning the A/F mix in the pipe?

9psi is considered low boost. For a low boost application, low to mid 12:1 A/F should suffice. If it doesn't, you have other issues, the first being timing either too advanced, or too lean.
