thx for posting
one of my friends was running 28-33 psi or in the low to mid 400whp range with pump/meth in his evo. he tossed a rod through the block not too long ago. id say he got around 10k miles out of it with a ton of racing. stock block with arp main and headstuds. this was using a 20g.
ive made 425 on pump with a b16/gsr combo motor. timing was safe and afr was rich. 18 psi off a 60-1. the motor has seen just about 10k miles, 30 track passes and around 10 dyno pulls. i coulda got that setup to around 440 on that boost level with a more aggressive tune. i wouldnt want to push it too far, it leaves very little room for any error or mishap. plus as people have been saying, unless you've got nice boost control, its real useless on the street. with a regular michelin tire my car would spin all the way through 3rd if i romped it hard

Not quite sure what iron vs aluminum vs open deck vs closed deck has to do with this thread. If the motor is tuned properly and not detonating its *** off then its pretty irrelevent.
I've made 425whp on my old B16/T3-67HO setup back when I used to daily drive this car, went 10.9@130 on 93 octane pump. One problem with pump is its consistancy, especially nowdays where some stations are using E10.

Re: highest hp on pump gas
You guys are seriously walking on a thin line between love and hate.
One bad batch of gas and kaboom..there goes your setup.
Stop trying to achieve a number...have it tune to where it is safe and reliable and stick with it. Finding the right setup is the key to meet your goal, not pushing your turbo pass blowing a hot air for that extra 5Hp..
Don't try to push SC44 for 500 lol...if you want to make 500 whp, then you should've gone with a different setup.

Re: highest hp on pump gas
I will also add this..
90% of the time, you won't hear a blown motor problem AFTERWARDS. Any problem for that matter. Every tuner always post a victory (dyno chart) but never a loss. Because a loss can potentialy ruin his business.
Just because someone makes 600 on pump gas, posted a dyno chart and a video, doesn't mean it will survive in different environment.
Just a $.02 from an O.G.

Re: highest hp on pump gas
umm what era of F1 was that in ???
also you are aware of the fact that F1 engines travel much faster than detenotion can occur right, on top of that F1 engines are nothing like every day street driven honda engines.

Re: highest hp on pump gas
That's in the current era. And it is for the exact reason you state. They run low octane because when an engine is spinning at 19,000 rpm you need it to burn as fast as possible so it will finish burning by the time the exhaust valve opens.

Re: highest hp on pump gas
I made 520whp and 340tq on 19psi on 92 octane pump gas, on decently conservative timing in the map...
Setup is 84mm gsr GE sleeved
9.7:1 cp pistons
Blox B cams
Gt35r .63ar housing going to a .82ar next week lol
3" Down pipe no exhaust

Re: highest hp on pump gas
I have a customer running a 84MM GSR with a 35R with the 3in outlet 9.5:1 compression, built head with type-R cams. made 522HP@22 PSI on a mustang dyno. I went for a little more, but started getting det on the plugs so I backed it down and left it where it was. The setup was really good, we tested the backpressure on the manifold and it was like 12-13PSI when we were at 22psi on the front side. I had about 15deg of timing at 22PSI at 9500RPM

Re: highest hp on pump gas
Thats a really good setup... But your timing compared to mine is 3x as much easily... i am at 4.5 degrees of timeing at 9k on 19psi 
still making good power.
Car has seen no signs of det on the plugs yet... Car is getting the .82 ar housing and a victor x IM on monday and getting retuned prob with some more timing, expecting right around 550 after re tune

Re: highest hp on pump gas
Just an example how much a turbine outlet matters.. I had another setup, identical but he had a 2.5in outlet on his 35R and his motor maxed out at like 450HP before having serious detination problems, and I only had like 10 deg in it at like 18 PSI or so.. Mabey I can print up both graphs so you can see how much difference .5in makes on the turbine housing.

Re: highest hp on pump gas
I usually run really conservative on timming, but this guys motor was fully built and he wanted to max out what it could do on pump.. PLus it just kept taking the timming and makeing more and more power lol.. what kind of dyno were you using?

Re: highest hp on pump gas
Very true, people really do under estimate the sizing of housing when they are trying to make big power #'s
Ill be going racegas tune soon for track season... Hoping for 650 and 425...
People that are doing these setups need to sacraifice that 1000rpm spool time for the bigger housing, especially since most are revving to 9500+

Re: highest hp on pump gas
I was on a dynapac... our's at speedfactory has been proven to read lower then dynojet and mustang dyno's..
HATCH34 in this thread is one of my close friends same tuner and same dyno and he made more power then i did on 16psi

Re: highest hp on pump gas
nice.. I know our mustang reads about 12% lower than the dynojet we used to rent to tune on.. not sure how it compares to the dynapack numbers. I though the dynapack and mustangs were pretty close.
