Are we using regular pump gas or anything we want. Cause if the timing is ramped up and it's using alcohol for fuel, then that's not the turbo making the power, it's all tuning.

Admittedly though, if that is only on 15 psi, then 392 is a boat load of power.

Noway, unless it was a motor run on a dyno by itself. The turbo does matter as far as size is concerned. But the Holset compressor isn't going to magically make more power then the garret compressor. The exhaust housing is a tad different, the internals are a tad different, but that's it. If Holset could make more power, EVERYONE would use it.

The average for a decent tune and well matched turbo is 10whp per psi of boost.

WD

i heard from a reputable source that per lb. of boost increases hp's by 7% of what ur motor is n/a. so that would meen that the ka per lb. of boost would b around 10-11 hp's.
check this out.

How it works:
In order to understand how this calculator works, it is helpful to understand the basics of supercharger technology and why superchargers make more power (check out our tech section for more on info). A rough starting estimate to calculate HP gain is to take boost (say 5psi) and multiply it by 7% (a constant) to get your approximate power gain (in our example 35%). Why 7%? Because 7% is approximately how much more air and fuel gets into the motor with each pound of boost that is added. To get a more exact figure, take 1psi boost and divide by normal atmospheric pressure, 14.7psi at sea level. 1 divided by 14.7 equals 6.802%. Under ideal conditions, you can expect to burn 6.802% more fuel and air per pound of boost. This is the starting point for this calculator, however, as boost rises above 5psi, other inefficiencies kick in, so gains above 5psi become progessively less effective in making more power. When you need to retard your ignition timing, which is often necessary when running a supercharged engine to avoid detonation, other timing inefficiencies kick in. This is factored into the "HP Loss due to timing adjustment", which is an estimate as to the amount of ignition retard that will be required at a given level of boost. To offset these losses, you can run a higher octane fuel or an intercooler, both of which increase your detonation threshhold and allow you to run more boost without experiencing detonation. For more on detonation, check out "Detonation, Knock, and Pre-Ignition 101".

oh and by the way everyone has been askin bout the strut tower, and that was some stupid noob **** that i did before i knew how to clock a turbo,i just hacked that ****,hopefully i can weld that **** up and fix it back close to normal.

haha dude.. i was thinking that was the issue when i first seen it... but when i seen the rest of the bay.. im like man he looks like he knows whats going on..

then im like ****, did he blow chunks out of the outlet, then i seen that your compressor shaft was still inplace..

looks good bro..

What manifold do you Holset guys run?

Any clearance with the master cylinder with ABS?

Just paid a deposit for a ETD manifold and was looking into a HX35. Just wanted to see if there was any clearance or fitment issues.

Yeah that was my car with the H1C. There were no abnormal timing changes at that time. The car just flat out made efficient power with that turbo. I believe I had stg 2 BC cams and custom intake at the time. And I was running a 50/50 E85/ 91 piss mix. The 392whp was on a 1 bar spring only, the boost controller wasnt even hooked up for that run.

that's huge, it probably stand still at idle. must be slaming you back violently when it hit.

sorry i didn't see this on the 11th. but as explained bigger holset may require some cutting and pasting

they are not direct bolt up turbos. you will have to make your own dump.... if you don't have a welder.. you can still get some mandrel bends once you have the turbo mounted and mock up a dump/down pipe... mark it tape it and take it to a local shop and have it welded.

I'm having a little trouble figuring out the best turbo for me. Ive got an rb20 and want to get a hx30 but was having trouble finding info on them. Looking for 350 to the ground and this is a drift car. What do you guys think? I have poncams and all the other stuff to support.

it would be a lot easier to find a hy35. It will suit the rb well. They usually have a small turbine side (9cm) so you would have a wide power band good for drifting. You should still be able to reach your goal of 350whp as well.

At first glance i though this was a hx35 because of the compressor housing discharge no facing forward like most hx35's. But i am starting to think this is a hy35 instead. Even though the compressor housing is differnt, the turbine is very small for a hx (9cm i think) and the chra and turbine are held together with a v clamp. What holset is this?

I need to get the turbine off to weld the wastegate shut and i need to clock it anyways. I am having trouble getting the two to come apart. I let it sit in penatrating oil for a few hours and then attempted to seperate them with a chisel and hammer. Don't worry...i was barely tapping it. It didnt move at all. Tomorrow i plan on hitting it with the air hammer (lightly) unless anyone has a better idea.

p.s.
Its not my turbo so believe me when i say i am being gentel (spelling?)
with it.

-Thanks

you said it has a 9cm^2 turbine housing right? yours looks identical to mine, except for the inlet. but mine has the v band clamp that holds the turbine to the chra.

mine was rusted together. i tried a lot of stuff, most of which are probably very wrong. what eventually worked for me was that i held the turbo by the comp. housing about an inch or 2 off of my work bench. then i wrapped the end of a hammer in a towel and hit the turbine housing with the hammer. it wasn't the "right" way or the best way to do it, but it was the only way i could get it off.

i hope that helps

Anyone here running a Holset HX40 on a KA? I know it will be laggy, just curious as to how much. I know it flows 70lbs/min, and that is quite a lot. Any info regarding the HX40 will be greatly appreciated. Looking to run it at 1 bar till I get pistons and rods.
Thanks a lot.

The twins car had a hx40 on it. They held the stock block hp record for a while till cory took it. They were on 30psi and made a little over 520whp i believe. Search for it and you might find their video.

As far as a hx52 goes.....they are huge. A local honda guy had one on his built gsr and he hit boost around 6K. When boost hit....you better be holding on to something.

this partiuclar turbine is not twin scroll. However the H1C on my 240 is twin scroll.
