6G Celicas Forums

Thanks mate. I would not described that any better


It is heat sink cover made of titanium fiber and has plenty advantages . Those spacers are not that big as it seems. For rear it is about design and front it is more about function (I need some space there ).

Talk about clearance!

Update: June 20.

Small step by small step... but again more close to result: custom made 3" front pipe ready to go



So with already installed HKS exhaust it gives for whole of length full 3" diameter at last.

Hi,

great to see you forward your project, what shoult be the end result of stage 4?

greetz

Hi Alex. Result should be "finished car" as I always wanted it = perfect Celica from my point of view. No more upgrades. No more plans. Just done at last.

Hi,

got it, and after the finish we do a further meeting

greetz

This is an hybrid based on a real Garrett GT2876R, and it has a quite different behaviour from the pure GT2876.


Malpaso, today I had the last test around home before the final mapping on the dyno, and with the latest map
I made on street, the peak boost is at 3800 rpm in 3rd gear, so probably I will gain other rpm when mapping to MBT on dyno in the next days.
As I told, that's so much better than a normal GT2876R I tested on a friend's ST205 that had peak boost at 4200 rpm.

Definitely WAAAAYYY better than GT28RS that, IN MY HUMBLE OPINION, is quite a wrong turbo for a street 3SGTE, as it gives no more power than a CT20B.... but it is my first choice on my 3SGTE-RAV4!

Who is this? Who is this mean-secrets-spoiling-person .


Thanks for update mate . Now is really only last thing to do: final dyno mapping session! I hope it is available to use soon and my suffer is at last over .

Cant wait to see the PHAT 4" intake you're going to have, right?

Update: July 24.
At last can share the news. The dyno day date is fixed! So can count loooong days till result is tested in Swiss Alps .



Gotthard Pass - Wikipedia link (and try to make few pictures there). Stay tuned

Enjoy those Alps for me mate.

Will do my best mate . True is you are... yes... the only one person who could be able to compare difference between OEM 3SGTE SS-Four and this final result...

On some of the same roads, no less! Hopefully there will be a next time and I can give my "experienced" opinion.

The only thing that matters is if second gear is enough now.

As some of you already know my car is back home because at last dyno was available this month... So the good news!



It was pretty hard because ambient temperature was 50°C (122°F) and took whole 8 hrs... Unfortunately despite superb job of Wolf_tm I have not climbed over 400HP as wished. That temperature was really killing... also idea to not use high octane fuel reached its limits (what was my fault because I did not wanted to be "slave" of only one fuel seller in my country cuz only Shell in CZ has and will have in the future high octane racing fuel for sale). So plan is in two months pass one more tuning (when ambient temperature is lower and with bit better fuel) and we will see what we will see . There are no mechanical limits to get there. Just tropic temperature and crappy fuel were only limits to get what I expected .

Still no need to be sad at all because:
- today is car mapped and ready to handle the worst fuel I can even imagine and will running safe for ever (even under crazy weather conditions) = what is more than everything.
- below 3800RPMs is car like little rumbling peaceful lamb () that takes 7.9 liter per 100kms (29.8 miles/gallon !!!). What is crazy...
- above 3800RPMs car turns to a beast... its huge change! When you hit 3800 it pushes you to the seat and continues up to red-line! When pushing the car to the limits it takes 13.1 liter per 100kms (18 miles/gallon) that was in fact also average consumption of my old 7AFTE . So in terms of this I'm double happy.

So overall impression is great and I'm happy having it back even as is because it is already different car that was four months ago. Thanks Wolf!

What's the number you ended up making? Torque?

But wow, 50C is hot even for Italy!

Great news martin, great news.

Is it sad I got excited over the 29.8mpg? Awesome work!

DAMN. I'd need around 12-13 liters to get 100kms

good work, withholding the power output i see. Tell us xxx HP @ xxxx RPM @ xx PSI w/ xxx RON

wont judge and doesn't speak poorly, i doubt im getting much more than 250awhp from my setup atm,

i expect with something over 1.2bar on your setup, you atleast have 320-340 awhp which is not bad at all


edit, ps: you may have a 400hp compressor, but im sure that t28 housing wont flow that much (less than ct20b/ct26 even) and you may need to go gt30 exhaust side and/or external wastegate , i think this may be holding back your top end. did you have the t28 housing enlarged with a die grinder? may help (at cost of spool).

a large external gate is a good way to gain flow at the top end without adversely affecting spoolup. i had my internal wastegate filled up with weld and grinded back smooth from the inside with the old gate door welded on to hold it together

For me it was shocking as well because expected exactly the same as you wrote... anyway I believe I did not do any mistake in measuring because had chance to test it in many driving conditions and did always the same thing. It started with full tank (that full I saw level of petrol inside filling pipe). Than:

Driving absolutely randomly (city, highway) in speed range 50-130 km/h (31-80 mph) 267 kms (166 miles) that again took full tank as before and filled 27.9 liters (7.4 gallon) = 10.4 liters per 100kms (22.6 miles/gallon).

Driving in the mountains, twisty roads a lot of acceleration (full throttle), road elevation 12%, etc. 292 kms (181 miles), again full tank as before and filled 41.3 liters (10.9 gallon) = 14.1 liters per 100kms (16.7 miles/gallon).

Driving between cities/villages in speed range 40-80 km/h (25-50 mph) 154 kms (96 miles), to full tank filled 12.2 liters (3.2 gallon) = 7.9 liters per 100kms (29.8 miles/gallon).

Driving highway only in speed range 120-160 km/h (75-100 mph) 571 kms (355 miles) and to full tank it was 63 liters (16.6 gallon) = 11 liters per 100kms (21.4 miles/gallon).

So as you can see that consumption is really variable and depends on driving style.


Honestly I would like to share with final numbers only. Now I just feel bad for my stupidity of using that low octane fuel so not taking it as "final result" at all... I should read about octane ration more before making conclusion "map it for 95RON". Anyway you are not far from truth . It is obvious you have own experience with setups like this .

Reason was as I mentioned we have 95RON as basic fuel here (in US i believe it is called "91" because rating is displayed in AKI not as in Europe or Australia). Some petrol stations offer 98RON (94 in the US) and just Shell and OMV (that is leaving CZ market btw) offers racing 100RON (96AKI). Price today is like 1.75 per liter ($5.50 per gallon), 1.90 per liter ($7.19 per gallon), 2.10 per liter ($7.95 per gallon), for 95-98-100RON fuel. As you can see my motivation to use 95RON only was big .

So since 95RON is really crappy fuel I decided to do one small trick with fuel on next dyno session. Mix half 95RON and half 100RON (or lets say 60% 95RON, 40% 100RON) to get something like 97RON fuel (93AKI). Car will be tuned to the maximum with this mixture and than used with 98RON only. That means I will have some kind of "fail-safe" when pushing car to the limits and gain expected power.


Not sure... you can compare:

ct20b
turbine A/R 0.35
compressor A/R 0.36

ct26
turbine A/R 0.50
compressor A/R 0.70

my baby
turbine A/R 0.86
compressor A/R 0.70

Anyway thinking about it overall more and more is better having 10-20HP less and run for 100.000-200.000 kms more for me... so definitely will not want map it higher than is safe for it.

ahhh .86 housing. it is more machined out than what i have .64 housing
