hybrid turbo upgrade


TT Paul

Recommended Posts

well ended up with syvecs now all working sweet in ttc mode and like it, but looking at getting better hybrids, i can do it myself as in fitting so save money and lbr !!;)

 

going to fone turbo dynamics and cr turbos for pricing,advise etc.. my first idea is just larger exhaust wheel, but saw something that said bigger an't better :rolleyes:..

as in larger turbines more lag! i have just reg size turbos with steel internals which are a little laggy but i'm use to that now, but blade pitches etc can be changed so seeing what other peoples thoughts

are regards these, not going single due to cost, run'n, more strain on engine.. just use what i got..

 

any tech input ideas etc.. before i buy

I know you said you are not going single but IMO you would be mad to mess about with hybrids, as you like a bit of spanner work I'd just build up a basic kit, log manifold, PT6262.

 

Run it at 500/500 and it won't be any strain on the engine, now you have a Syvecs make use of it.

personally would go with a 6266. It spools the same as the 6262 and full boost by 3500 rpm on a tubular manifold. no TT hybrid is going to match that

And don't forget it starts building boost by around 2200 rpm so going from 2200 rpm to full boost feels almost lagless comparing to a TTC going from 2k rpm to 4k rpm is night and day

i thought this might happen i know what every ones saying its just personal preference, just the route i feel like doing and fitting a single kit is abit of an ask i know to a degree, what to do but its the unknown..

 

and the fault with the running high rpm i think was due to a split in vac pipe

Someone take this guy out in a single turbo supra...:D

i didn't want to loose the low down boost response but from what I've been seeing on a small gtx35 there isn't any loss only gain.

 

This was a dyno i found of a 0.82 T4 GT35 at 1.3bar and 1.5bar boost pressures compared against BPU TT (i can only go on the posters accuracy and word, so don't shoot me if its wrong) But going from other GT35 owners they have said its about right

again its build cost, fuel cost, etc.. a single will be more £s over the life of the car

 

I know it offers more power which will be more strain on engine autobox then be upgrading that, built box, cams, bigger injectors .. a

 

people are missing my point regards hybrids not a single all replies are good if I was going single! I'm going to use what I've got just bigger hybrids and I've not had any

issues with them so all the haters i''ve proved wrong, and how many times I've read all these big single supras for sale spent £££s but don't get time to drive it, so they sell it at a big loss

or break it .. and some say the car is not as good to drive day to day?

but TTC acts like a small rubish single anyway, if you want to keep the stock twins why dont you just keep it sequential, as you cant really gain much uptop why not try and gain it down low ?

you already have hybrids which are not that old i believe , if they are shot already then you will save money going small single , a hybrid stage 3 rebuild cost me £1,300 and i fitted my self they lasted a year(my fault posible but was ment to take 1.6 bar but i had over boost of 1.5 and the destroyed them selves), so that would have been another £1,300 for a rebuild but i picked up a second hand single turbo kit for that , (xspower kit but with turbo binned and a decent one put on instead which kept cost down) this single turbo kit has out lasted my hybrids as i have had it 2 years now and my auto box has covered 160k MILES 70k at bpu and 10k at 524bhp 510ftlb with the single

some people love TTC

but i for one dont was alot slower around town and thats where most of these cars are driven.

 

if TTC was better why the hell would toyota waste there time and money and put the sequential in the supra in the first place.

Wait until the sequential system starts misbehaving ;)

 

But yes, you did ask for opinions on hybrids. I think enough people have let you know it's not really effective and you've already got most of what you need for a single, but if you wish to proceed with hybrids anyway, then that's fine. You'll likely see about +20bhp at best and higher EGTs, and there is no expertise in this area as no-one does it, so don't bump the thread too often due to a lack of responses ;)

That's my GT35R dyno overlaid with a TT dyno, it is an accurate comparison, (well as accurate as you can get when you overlay 2 separate dyno graphs.)

Due to gas flow restriction on a stock manif / DP / MP combo, you will get higher EGT when pushing things to the limit.

 

One option would be to go for Alex's option. An ehtanol mix will drop your EGT considerably.

ah thanks nic. was perfectly what i was looking for and sealed the deal for me going for a single gt35 setup.

 

i don't understand the comments of "if i go single it will cost more because i need fuelling and better brakes etc" People seem to think you have to go mad on power with the single. Regarding putting strain on the gearbox and then needing more parts like fuel and brakes. what difference does it make ultimately if you are making 500bhp on a hyrbid TT or 500bhp on a small single?

 

From the single setups i've been looking at and how i plan to build mine, the single setup is going to be so much more reliable than the TT> 1 turbo over 2 for example, much less complications with pipe length, Remove so much mass from the engine bay you can actually get in the turbo side and work. With a single setup its a manifold, turbo and wastegate and some pipe work. By nature that has to be so less complicated than the sequential TT setup

You won't be disappointed Tim, it makes for a very responsive setup, the key will be getting traction in the first 3-4 gears. :)

Completely agree, mine was far more reliable after the single install.
