can a 13b even spool up a twin 3037 kit real good or is there alot lag and how much hp at 15 psi?

im4u

can no one help a damn person out?

Lost Time

357.6 RWHP @ 15psi
Full boost by 3210 rpms.

Good thing you responded lost time, couple more hours and I think his head would have exploded

nocab72

Actually I thought it was more hp than that, but laggier.

Like 413.4RWHP @ 15psi, with full boost not until 3325 rpms.

That is pretty nice but... dont those turbos reach $10,000+ You could get a T78/T88/RX6 and still have a bunch of money left over. What about higher boost.... Those twins might be able to push out some crazy numbers with race fuel.

JoeD

are you guys thinkaing about the same turbos?? he is talking about the HKS 3037 kit, ya know...like the HKS 2835 kit for the Supra, which is one of the laggiest turbo setups you could buy. well, the 3037s are bigger than the 2835s, and i know there is no possible way of those turbos spooling full boost before 5000. even the quickest spooling turbos for the FD (RX6 and T04E) dont hit full boost before 3000. (yes yes, i know....spool up time of different turbos is dependant upon the setup of everything esle, but that is beyond the point).

I'd have to agree with JoeD...I want either 99 turbos or To4e (60-1) nexttime...too bad I only have 6k miles on my factory new ones...might be awhile..hopefully..or maybe not

I was about to say.... Maybe they mean it gets to 15psi by 3325 rpms. Those supras boost to like 30psi by 5k rpms.

Here are the beautiful things

Doesn't the KSP engineering FD have twin GT 3037's? I know it makes upwards of 500+ hp.

Johnny

I dont care if it makes 1500hp...I wanna see it charted against boost pressure,and rpm and torque...

I hate dyno queens.....garage queens are ok

Did anyone find out when these huge things spool on an FD?

JoeD

the spool of a turbo depends on many things, but mostly header design and A/R. there is no way of knowing the spool characteristics of these turbos because no one has tried them yet.

but dont expect you can strap on a large turbo and make insane power (remember folks, we are talking about FDs here, not Supras ). you could be running a ****** T100 or something crazy on an FD, but the bottleneck is the porting of the engine. why do you think the upper limit on streetable single turbo setups for a 13B is in the range of 450 rwhp?? because that is how much the porting will allow, regardless of turbo size. if you want more than that, you are looking at two bottles of the big ones or bridge porting.

bottom line, on a streetported motor, HKS Twins will make just as much power as say a T04S. but the Twins will make the same power at a lower boost pressure because they flow more.

Good info, thanks I still have yet to drive/see a bridgeport. Most people say it's on the border of streetable.

JoeD

how 'bout not streetable at all.

Yes, Friends of mine Okamoto and Uchino have 3037twin by KSP.
I have uploaded the pic before.

found the pic



Thats a nice engine... what are all the specs like port, spool up, max boost, you said something around 750 hp? Do you know if your friends lowest time in the 1/4?

If anyone is familiar with Axia Sport, they're now into the 58's at Tsubaka Speedway, which is nipping on the heels of RE's SuperG2000 mobile, in the 57's, and may have eclipsed PanSpeed for 2nd place. I think their official time was 58.886 and to make this post relevant, they're using twin 2835's. I believe issue 14 of RX7 Magazine has a writeup on the car. I'll scan pics of the setup later this evening if I have time. I think the 30 series would be a bit too laggy. I've been researching the GT line for some time and may end up going with a single GT3040 or a straight GT35. According to the aussies, the 30 series is the "grunter", great for low end and midrange and a decent top end, quick spool up to boot. No real numbers in terms of spool up or top end hp however. Just about ANY turbo is laggy on the Toyota, part of it's nature being an inline 6. Actually, it's probably pretty dependent on it's turbo manifold design too.
