Is the C30 with the HBP a risky setup longer term? Using 96% of the unit's capacity has me worried for track use. I can't use the C38 since I don't have E85 and won't have a built engine.

It sounds like I can safely run the HBP on 92+ with the C30 when using an Ace header, but I still want to be sure I'm not placing unnecessary stress on the Rotrex unit.

Stress on the engine is the main concern not the compressor. Regardless of C38 or C30, support mods, including engine rebuild, are necessary for HBP upgrade. CSG Mike has also mentioned that ACE header upgrade is also recommended to do the tune most efficiently.

I installed four clamps on both ends of the two hoses connected to the solenoid under the intake manifold. The difference is huge. Power and even mpg are noticeably better. Check the following thread. I should have done this when I installed JRSC in 2016.

With a new MAF sensor (probably, o-ring replacement would have been sufficient) and the clamps, P0172 is completely gone. My engine is singing again.

Apparently on 92, when paired with the ACE header, the HBP can be run safely. I’ve confirmed this with CSG multiple times now. No supporting mods needed given the relatively small power bump on pump gas with the HBP.

My main concern is longevity of the Rotrex itself given that it’s being used at almost full capacity. Does the redline remain at 7400?

I saw virtually no power increase on this setup so don't recommend it. The HBP is really designed for E85 or race gas and in that case you'll need a built engine.

To answer your question though, it depends on what you consider as 'risky'. Yes, you'll wear out the C30 faster. How much faster? I don't think anyone can answer with any certainty.

Once you go over 8psi you are playing with Fire. I believe the stock pulley is already pushing 10psi close to redline. HBP can be run but just that much more risky.

I believe you can have the redline set to whatever you want. Although most people don’t go above 7600. With boosting stock motor probably don’t want to rev past 7400.

But again Some people blow the motor NA or on super low boost. Some people are runnng 14psi and going 50k miles Strong. But the more boost the greater the risk and chance of blowing up your motor. Generally 8psi is considered the top ending of “safe” on stock internals.

FYI: Currently on JRSC C38 with 700cc injectors and DW65c fuel pump; stock internals and ceramic coated ft86 speed factory catted UEL header. Manual transmission redlining at 7690 (140km/h) on third gear pull (according to logs). I believe I once saw it redlining at 7890 but could not find the log. So... No problems other than loss of boost due to altitude (5250ft above sea level) and high oil temps (110 - 120C with spirited driving). PS: Ceramic coating the header helped quite a lot with engine bay temps.


Best.

Please qualify that statement, because it's absolutely untrue.

How does water/meth factor in getting more reliable power?

So you’re saying assuming everything is setup correctly and tuned properly there is absolutely zero risk to boosting even 9+ psi on stock internals? And Not an inverse ratio of more boost to lower average life expectancy of the motor?

You’re saying if I have 100 NA motors, 100 boosted at 8psi, and 100 boosted at 12psi they will all last the same amount of time on average? Each group will have the same amount of pre mature failures and same amount hitting 200k+ miles with no major issues/failures?

I think that is what he meant by “qualify that statement” because “playing with fire” sounds more extreme than you saying there is a higher risk. For instance, vegetarians live on average six months longer than the national average, but if a vegetarian said eating meat is playing with fire I would laugh. Similarly, it is reasonable to conclude more psi therefore more risk, but that doesn’t mean someone is doomed to blow up their motor.

Take Edelbrock. The stock kit comes with a pulley that greatly exceeds 8psi and the powertrain can potentially be warranteed for 30k miles or something. Hardly playing with fire or Edelbrock is insane.

Is the air filter that comes with the kit supposed to be dry or oiled?

Included filter is oiled

It is oiled, and can (should) be cleaned at regular intervals.
