Any new updates from anyone?
Any new updates from anyone?
Virtual Works installed my (Stu and Aaron) Hybrids. They also did the wastegate spring mod although my boost still drops at redline about 2 psi. I only have the bleeder T mod to control boost for now which is a big issue. I am boosting 14-15psi with a second of 16psi. I am going to get a MBC and turn it up to 19-20 psi and tune my SAFC-2.
The turbos seem really laggy though. Well maybe just the second turbo, it's hard to tell. The first turbo seems to boost up instantly but it takes all the way untill 5k maybe more rpm to get full boost with both turbos. I don't know if this is because the bleeder T mod or what.
The turbos seem to have a lot of potential though. It seems like they have way more in them, which I'm sure they do. Will I have to use a boost controller for both turbos like Stu to eliminate the second turbo lag?
Hammerhead...any news? I hope all is well with the Dawg and fuel system/upgrades etc.
stock fuel... meth kit with 100% meth for added fuel 21.4psi falling to 20.5 by redline 500/480. Feels great. Under closer examination Turbos are definitly laggy. Not incredibly noticable on the street.
Even with a Huge spring on the WG I cannot make anymore than 21.5psi. I think the OEM WG actuator was stronger! I have some Ideas, if all else fails. Ill weld it shut and put a Tial on it.
Is there anyway you could post up some graphs?
There is so many other factors involved in order to compare things. So far, hammerheads GT28's have not proven any gains to the T3 Aarons. Which really doesnt surprise me since these are so close in design, power wise. ALthough hammerheads dyno at around 500 is from a basic BPU car. So that is encouraging.
I assume he will be posting up his latest dyno here any day after fixing is wacky waastegate issues.

Tomsid used a modified stock manifold and the last dyno he made around 420 rwhp here in sweden which propaby is like 450+ in the US since our dynos often show lower hp than the dynos in US, that power was made around 1,2 bar if i remember correct.
I spoke with the company here in Sweden that still do the CT12/T28 hybrids and they are full BB so i think i will have a go with this setup.
A evil Protomotive Beetle :-).
EU-Spec. 6-speed Supra MKIV aka Eagle II.
Correct the company is GIK in Gothenborg on the west coast the price nowaday for a set is around 24000 skr = $3400 but these are ballbearing T28 they say they are good for 660 hp for a pair , which seems to be the common sensus i have a pair of these for my Skyline as well.
Come on guys we want updates and more dynos on this setup ....... :-)
Keep up the good work
Yea i thought Ken Henderson was suppose to dyno his like last week?

Thanks, my friend,
I'm impatient by nature, but one thing the MKIV Supra aftermarket has taught me over the years is patience. I take a pretty comprehensive and thorough approach to modding because I only want to do things once and enjoy the car for years thereafter. My tuner, SP Engineering usually has almost everything in stock or immediately available. The problem is that we've never ordered new parts for the OEM twins or, in this case, the Aaron hybrids because the twins have ALWAYS been coming off cars that SPE has built. So my turbo gaskets, studs and whatnot have been trickling in, literally, one day at a time.
BTW, if any of you in the western U.S. need a fan shroud and can't find one, it's because, LOL, I own them all. Not literally, but I had a cracked fan shroud on my black car. Ordered a new one and it came scratched. Went through this exercise FIVE times and called Curt. Curt said every shroud he had in stock (5) had the same scratches and that they all come that way because of shipping and handling issues. Finally, I took the shroud off my red car and installed it on my black car so I'd have at least one Supra to drive around, used some 5000-grit on my new, scratched shroud for the red car, along with some ABS plastic polish and got it to look reasonably OEM new.
As you guys know, a day in the MKIV Supra aftermarket can easily turn in to a week and a week into a month. I deal with delays better than I have in the past, but it is still a lot of work for me. If I don't work at it, I'll start jumping out of windows again so, hopefully, things will be all good within a day or two. As always, time will tell.
LOL @ Ken's stories. You'll get through it my friend!
You guys that are running lean...what ecu are you running? I may have missed it in the thread.
Im surprised to see running lean at 500whp. Well, not completely surprised, but with OBDII im seeing 18psi and no leaning out. In fact, i had to lean it out some to even get into the 11's A/F wise. This is with a 67mm DBB, which also makes ~500whp at ~18psi
BTW where do you get 5000 Grit Sand paper... all i have local is 2000.
Also, regarding running out of fuel. 11.6 a/f 500whp injectors will go 100% and car will lean out to 12.0. It is going to keep going further so there was no need pushing it till I get a fuel system. Aem computer.
hammerhead, any update's ?
