Hopefully someone on here has a Go-pro and can take a video of their 0-60 on the Stage 2 setup. I still don't think the video would do it justice, but i did do dyno testing to prove results.

I totally agree. Those results were done with a catted down-pipe, HPS intake tube and Stage 2 tune on 93 oct fuel. I still believe that there is a little more room for power improvement on the stock turbo, but more R&D needs to be done to ensure reliability as well.

I did 245 whp but i have a decated downpipe so there is the small difference. the car is quicker for sure but from roll racing from the dig its not that quick. i raced an rc350 and i got him but it was really a short race. I raced a wrx and i got him too. i mean i thinK that climate conditions are an important factor .i live in miami the humidity and heat right now its crazy but i bet in november or so its gonna pull harder. Im gonna do a dyno test by then.

The most difference its gonna be noticeable on the highway for sure and the car around town its way more fun than before you just gotta play with the gears that after the tune they are faster too.

i would say it does need a little more of power i would be happy with 260-280 whp. i mean at this point with downpipe full exhaust and an intake i would expect a little higher hp numbers.

Sheddy

Yup, i have way more fun with the car now. I would love to see the dyno results with the E30 fuel tune. Due to the lack of displacement, turbo lag is inevitable, so only run on a roll lol.

I agree with all of you but that is just calculation. I need a video lol

In addition, HP at cranck, at the wheels means not a lot for me...

I need number in HP like Lexus provides it

daniellina

Thats a simple calculation right there most of the times a rwd car will put 15% less than the actual hp to the wheels 245*100/85

So we are talking about 288 hp but. the hp that counts its how much power you can actually put down to the ground

Sheddy

Lol, WHP says a lot! Like Daniel said if you want crank numbers which is what most manufacturers state, take the WHP and add 15%.

239WHP= 274HP
273WTQ= 313TQ

ok thanks for the info, is there another calculation to do to adjust because I run RON98

Are you sure you're reading the posts correctly (maybe it's me)? It looks like the IS200T went from 180whp to 224whp on the stage 2 according to Sheddy's first post where he references WHP. The 224whp is quite a bit below the RR Racing results for the IS300 with tune/header/exhaust of 285whp (60whp). Of course, I'd love to compare a downpipe/full exhaust system tuned on the IS200T against the V6 engine which seems to be limited to that 240-285whp range w/o forced induction. If the turbo engine can be safely bumped to around 250whp, then many of us would be happy with the engine. Otherwise, I'd rather go with the tried and true reliability of their workhorse V6 motor.

Sheddy

Those numbers were from TTI's testing.

These are my actual results done on a dynojet.

i eat 350s for breakfast and thats been tested oh am not even boosting yet trust me the tune unlockes allot of things like Throttle and Vavle timings, and butt load of other things...all that makes the numbers truly irrelevant to some extent, but rather how the car response with u go WOT is what matter and when and where the power hits, and if u have doubts go and meet Sheddy for a friendly race with a 350 and lets see how it goes

oh and this is coming from a guy who is an X owner of a 350 3IS and now a proud owner of a 200t

Is there a calculation to adapt that result to RON98 ?

E46CT

if you happen to come across one on a track, post a vid.

Sheddy

98RON is equivalent to 93 oct which was used in that test.

LOL, Sorry guys. but i would leave the racing for the more experienced driver. I simply mod this car for my enjoyment.

Thanks for your comments. I'm hoping to pickup a used IS next year, and am closing watching the tuning/reliability of the 200T play out. I was originally set on a 350 F sport RWD model, but now I'm contemplating other options especially if the 200T's show great results.

Hello every one

There are allot of things TTi is working that honestly I cannot get into the details of at the moment, but I can guarantee you that soon 200T will be playing with the big boys

We are working on many modifications from turbo to engine to exhaust and more, and when we are done 200t will be in a different category, we only ask you to support us and give us a little more time....its going to be worth the wait for all 200t owners.

We are ready to answer any question regarding the technicalities of our tune/modifications and we are ready to support and accept new ideas, ultimately what we do will benefit everyone even none 200t owners, since all new Lexus cars share similarities in their ECU ROM who knows whats next.
