Hiboost vs. iON?

[HiBoost TS]

Hello Guys,

I just want to share the valuable information I was able to get having the oportunity to dyno both cars, the same day and in the same dyno.

Yes, the cars have different setups but very close as the GT28RS and the VF22 are pretty much equal. Both are ball bearing and have pretty close turbine and compressor sizes.

I was surprised when our car made more HP since we had the stock midpipe with cat converter and a 2.25 Bosal catback while Jared's had a full 3 inch from the turbo back.

I really thought that the GT28RS would make more HP at top end because it is a bit laggier than the VF22.

Anyway, just want to give the information we get from all this tests and really appreciate all the guys who have trusted their cars to us to get the most out of our proteges.

By the way, the downpipe was tested for fitment and it fits perfectly and made a big difference in throttle response, quicker spool up and steady boost. (thanks to fastmp5 for letting use his car)

good info !

 

[FSDET]

so when can we see a rematch with jrods fan and mani fixed ?

so when can we see a rematch with jrods fan and mani fixed ?

We are hoping to get things fixed and have the car 100% by the end of August

Thanks again for everything Juan, Looking forward to hooking up with you again soon to have the fully functional car ready to go.

i'd go with hi-boost personally

 

[iON Performance]

HiBoost TS - Thanks for chiming in Juan; in regards to the VF22 vs the GT28RS, I'd have to say they are anything but similar. We've been working w/ the IHI turbos since they debuted on Subarus; the IHI's turbine shaft/wheel + compressor side are all lower inertia then the GT28RS (just due to size). You'd be comparing apples with oranges between the two unless both set-ups were on the exact same car.

If the map on the Haltech was based on the VF22; then the GT28RS would be further disadvantaged, since the various factors that determine maximum power require different fuel and timing curves.

We're definately interested in seeing Jared's car back to proper working condition (ie: working fans, non-leaking exhaust manifold, and properly re-installed exhaust) so that the proper map for the Haltech can be made.

I say they are similar not the same. The mapping is not the same as we spent some time in the dyno to tune right. In fact we had to pull a lot of fuel above 4000 rpms in comparasion to the IHI.

Less fuel means less power at the proper Air/fuel ratio and we had to pull around 10% and there is the difference in power. We improved from the IHI map to the right A/F ratio on the Garrett, 20 WHP.

And yes, I want to see Jared's car working right.

But, we will keep working on both setups to get the best of these cars.

HiBoost TS - Juan, the VF22 and GT28RS are not similar; They are totally different species in terms of original intent of design.

In anycase, once Jared's car is running right; the 10% fuel that was pulled will have to be added in (and probably more fuel as well). The crack in the exhaust manifold as well as the down-pipe not being installed properly will definately cause this to happen.

Anyways, we'd like to see what happens with the IHI route We've hit the brick wall with the IHI's on Subarus already

chillinmcmillan - Gains maybe "similar" however your maximum thermal capacities would be different due to the cores. FYI, we use full stainless piping & SS t-bolt clamps in addition to 4ply silicone hose. So depending on geographic region; corrosion maybe something you would be concerned about.

Doesn't Porsche use mild steel pipes?

 

[jred321]

do porsche turbo's ever see winter?
and i don't think porsche is terribly concerned about longevity. mild steel will last a very long time before corroding completely, and by then you're out of a warranty anyways so i doubt porsche cares.

 

[Heathen23]

really? sounds great.......... does anybody know any knowledgable MSP owners in NC???

Nope. We are dumb (wink)

PM me anytime if you need help with something or have questions on my set up.

 

[StreakinOraNgeX]

Quick questions, with just fmic at stock boost around 6 psi, Juan and Jack estimate at around give or take 20 wheel horsepower?

 

[iON Performance]

StreakinOraNgeX- from our own testing we saw a ~20whp gain @ stock boost level on a stock car (note stock boost was only 5.5psi peak on our prototype car)

 

[StreakinOraNgeX]

Because I'm probably off or just tripping but I have the hiboost kit and it feels fast but not twenty wheel horsepower fast

 

[StreakinOraNgeX]

they both should be at around 20 horsepower though right give or take 5 hp

 

[iON Performance]

StreakinOraNgeX - it really depends; we can't really speak about the hi-boost kit. But if you're @ 6psi with our kit, you'll be making a little more power then ~20whp.

 

[StreakinOraNgeX]

So I might be misinterpreting but are you saying that with upped boost the efficiency of the intercooler rises, ie charge temp and horsepower?

 

[iON Performance]

StreakinOraNgeX<SCRIPT type=text/javascript> vbmenu_register("postmenu_1105540", true); </SCRIPT> - 10psi boost w/ the stock I/C set-up will make less power then 10psi boost w/ an aftermarket FMIC I/C set-up. You will also be more resistant to heat-soak w/ an aftermarket FMIC set-up.

Efficiency of an I/C is rated in terms of pressure drop across the core. As well as it's ability to create the maximum temperature differential between the end tanks (in/out)

 

[03MSPRO]

Ion,
what's the pressure drop across your IC?
Spearco's ICs have a pressure drop of about 1 psi?
