Today was an awesome day.. after months of emails with a customer of mine walking him though his build he showed up today for the tune. Let me start off with saying for the last few years I have been waiting to have a customer build a suby like this... and finally I got my wish. 2006 Sti Mods: Sleeved EJ257 Block 8.5 to 1 compression Carrilo Rods K1 Crank 79mm stroke 1600cc injectors Dual Bosch 044 pumps GSC S2 Cams Cosworth Intake Cosworth CnC head 1mm oversized valves Custom FMIC HTA86 TURBO Tial 44mm wg AEM EMS (TopSpeed Tuned) I am probably forgetting some small details, but thats the engine stuff atleast. When the car got here we pulled it off the trailer and I loaded one of my basemaps to get the car fired up and strapped it on the dyno. Impressive to say the least.. I maxed out the 1600 at 32psi @ 7300rpms, otherwise I would have upped the rpms. But next thing on the list is the new 2200cc injectors a larger hotside and a retune for 40psi :naughty: Until then here is the final graph from 32psi on E85... TopSpeed Tuned FTW!!!!
for realz.. still had the .82 backside on it which is a bit small for this power level. Which is why the power falls off in the higher rpms, or so we will find out when I retune it with the 1.06 hotside.
think the HTA is worth the money? and would you recommend sleeving a block with that setup? or would the factory liners take the abuse? these questions are relevant to my interests. :banana:
Factory sleeves are good for 26-28psi, anything more than that and they will oval. In drag race situation you can run them at 30-32psi for short burst on the factory sleeves but not sustained. In any event if you really plan on making big power (ie: over 600) you need to sleeve the block.
My leghumping is reserved for instances when crappy tunes are made better This one is good from the get go. That's impressive Doug. Is this the highest hp Suby you have done to date?
650whp must be insane to drive! Is this a dedicated race car or is it running around the street somewhere?
I can't remember if Dan Lowman's STi made more power or around the same....If he did, that was to the crank, not the wheels
I think Lowman's car was around 620hp. That was ages ago so I don't quite remember. Lucy was a dedicated track car but power is power. Regardless I'm very impressed with this powerband and how smooth and progressive it is. It's not like WHAM boost HOLD ON FLUX CAPACITOR ACTIVATED! It's s nice progressive pull when means it'll do a much better job putting the power to the pavement....although I bet it still LIGHTS up the tires.
Dan's car made 606.. IIRC and i never dyno'd lucy on the kill map. However she did make 580whp @ 26psi
http://www.youtube.com/watch?v=LRXhiKKWHoM Here is a video of Lucy making 520 on low boost map 24psi... not to mention that was on Cobb's "low reading" mustang dyno @ 4400 feet elevation She was a mean little girl too!
riding in Lowman's car with Doug made me realize he isn't afraid of death! Great tune, I hope the diffs hold out
yeah thats what i remember. that, and i think someone said in the same thread on the topspeed dyno on that setup would probly make well over 600hp
yea.. I know the customer is going to swap the .82 housing out for a 1.06 to see if we can gan some topend and loose some exhaust backpressure in the manifold.
*Cough* no other details about said fueling system.... *Cough* http://forums.nasioc.com/forums/showthread.php?t=1238595 Siegel
FAIL... where did they install twin 044's in a subaru???? Props to AMS though for testing flow rates of different pumps.
Would it matter if it's in a Subaru? One of the charts shows the flow on their test rig of a twin 044.
It was that test and a long phone discussion with a Bosch engineer that made us pick the Bosch 044's... Siegel
Cool... we had a set of twin 044's for clarks car that we were going to use to replace the aeromotive pump. But after alot of research and talking with numerous other fuel pump mfgr's we decided to ditch the 044's and run one single weldon. No point of over complicating things with twin pumps when you could just run one pump. Since the aem is turning it on anyway and we all know twin pumps are a dangerous thing since its super hard to tell when one is failing.
It's spelled "Reel" and as for innovation, unless you have a pump that runs on moonbeams and is variable from mundane to unfreakinbelievable flow, it's adapted at best. Now if you installed a failsafe and warning light to show a pump failure, to me that would be innovation.
maybe, but if you have a closed loop system it can detect the fuel pressure or flow and throttle the boost or wastegate there is a possibility of saving the engine. Twin pumps can be complex but it can also be simple if proper fuel feed to the rails
