AMEN!!!

comparing things at a certain PSI isn't very accurate anyway.
Stock turbo @ 15psi vs Good sized T04 @ 15psi = HUGE difference in CFM.

CFM is what related to HP being made

I was under the impression it was a mild street port. Thanks!

Heaven forbid! Maybe a correctly engineered to4 on a well prepared motor with non "big tunner" parts may make more power?... lol

It is funny how guys like HKS buy from Garrett (As do a nother famous TURBO Brand in the US starting with T----NETICS) and simply make another casting or two then sell it for 3 times the price cause it has HKS written on it!...

You do not need a T78 or a
HKST51RSPL.*#@!*#WSG to make power. As was said in the above post these things can be done with the genunie equipment so long as the person you buy the stuff off has experience with it, it looks as though XS Engineering has that experience.

It is very possible to do this stuff, we in Australia have been doing it this way for years (maybe cause we are tight *****?) It is funny now that we have some people here who say now that you need a Greddy turbo this and that to make power cause that is how the Japs do it! oh and by the way you need to pay $6000 Aus to get one! LIKE **** you do you magazine reading idiot! Go but the same spec or better turbo from Garrett direct or through a good reseller and pay half that amount.

My case in point Look in your own Back Yard...Able Ibara runs a Garrett turbo T4/5 series on his R100 and RX7 this turbo in Aust costs around $3000 no more! His car is very fast the last time I checked?

In Aust the fastest "true" street rotary 7.9sec 3rd gen (no space frame lightweight) runs a "*******" Garrett turbo which can be bought new for around $2500 maximum.

I personaly do not think it is necessary to fork out big bucks for Jap turbo's when at the end of the day they are not engine specific enough and you can never configure them to your own spec like you could with a TO4/5, however there is a **** load more time effort and work involved in making you own kit up...which you do not have to do with a Jap kit

I wouldn't post any BS flags. That is my friend's car and i've seen the dyno graph and him making passes on the street. Plus how can someone running stock turbos post a BS flag about someone, especially another rotary, running a single turbo.


I don't have to have a single turbo on my car to be able to post a B.S. flag. Look at the posts on this thread. There are guys on here with a T-78 running 20 psi not seeing those numbers. If he's got that kind of power, that's awesome...take it to the track and post the slip. If it comes out like it should, I'll post an apology. Until then, it's apparant I'm not the only one saying it's possibly B.S. I'm just the one who stepped up and posted.

"I don't have to have a single turbo on my car to be able to post a B.S. flag. Look at the posts on this thread. There are guys on here with a T-78 running 20 psi not seeing "

I have seen a few other cars reaching the 475rwhp area on 15-17 psi of boost. on a 62-1
do you think maybe its the person who ports/builds the motor that is the main diff.

maybe people are just mad because they are not getting that kind of power and have to run more boost?

I hope to add to this idea of less boost more power, with my own dyno #'s when my motor is back in the car.

I believe the XS kit run the 60,62 or 63-1 Garrett Turbo size.What most people don't understand is that the entire combination of parts is what makes HP. Some people are just better engine porters than others and hense get better results.If your motor is done right it's pretty difficult to beat one of these turbos at 15 to 18 psi.Bigger turbos does not instantly equal bigger hp!

I don't think there is any B.S. in this post, I think some people are just way too big believers in t78/t88's, yes they are huge turbos and when setup right, can make big horsepower, but I think like another person on this post said, that too many people buy off the shelf kits and expect that their car is going to make way more horsepower then someone else who bought the same kit. Personally to me, 425hp on a t78, that you paid maybe 7500.00 to setup, is not at all worth it. And who knows maybe this person knows how to port a rotary or knows something most people don't. I think 477 hp on a t04 with no nos is very very good, and I think it should be an encouragment for people to go with turbos other than t78's, t88's, and t51r's.

XSPOWER

Just to clear up any confusion, the XS T04S kit is a complete bolt-on kit that includes an XS designed cast iron exhaust manifold, Garrett T04S (the original, not the knock-off 60-1), thick wall downpipe, HKS racing wastegate (50mm valve), dump tube, all necessary hardware, gaskets, and plumbing, etc. for $3699.

You cannot bolt on a T78/T88, T66, T70, etc., and expect to get 500hp out of a stock engine or even ported engine. The port has to be designed for a specific power goal while keeping in mind what size turbo is going to be used, what kind of power band is desired, what kind of gas is going to be used, etc. You cannot purchase and engine with joe blow's "special" streetport, bolt on a T88, and expect 500 hp. It simply doesn't work like that in the real world.

The car at XS was designed to have high useable power on the street. This is why the T04S was chosen. How many of you guys drive your car only at the drag strip? Very, very few I assume. You might run your car at the stip a couple times a month at the most. With this kind of setup, you can have big power on the street and run decent times at the strip. This car was built to showcase the fact that you DO NOT need a big-*** turbo to make big power on the street. Although the port is on the larger side, it is still perfectly driveable. What makes this possible is tuning. The Power FC is an excellent ECU when in the hands of a professional tuner.

Soon, this car will be tuned on race-gas and will be heading to the stip. But for now, the dyno-sheet is at <a href="http://xs-engineering.com/asp/news.asp?id=56&version=0">pete's FD</a>.

Thanks! That dyno sheet shows 460 rwhp at 16.4 psi. We've been told 480 rwhp at 14.5 psi...which is it?

DefBringer

What is that dip around 5000rpm?

tristarx

I saw 467rwhp, but the graph shows 460.7. No biggie. Some guy on the forum called XS and said they were informed 477, so I would assume miscommunication.

Whatever it is, it's MAD POWER.

Well XSPOWER I agree with you those numbers look pretty realistic to me, my set up is a bit more extreme in that I have a perfect tunned length race manifold...v'large rear housing 1.32 a/r, my own design IC etc and Biggest street porting housings will allow. I use 14.5 psi (1 Bar) and make 450rwhp at 8200 to 8400rpm and has made 510rwhp (590BHP) with 20psi (1.38 Bar) boost at the same revs.

What the **** happened to the rest of the responces in this thread !

I am posting here that the claimed power figure of XS is optimistic and I do not agree with it for the parameters they state.

There was a wealth of information pertaining to this particular post and it has all been striped !

THIS IS FUCKED !

Hey Rice Racing:

Im also a non believer of H.k.s and Greddy products... It seems everyone here likes to follow what everyone in the magazines do.

Hey maybe the person who deleted some of the responces works for Greddy or HKS...

Hey Rice,
What posts were deleted? I didnt touch any of them.

XS's claims about their T04S are pretty much right on.

I have a customer that has put down 48? RWHP at 18lbs of boost with their base T04S kit. That was with a stock motor, no porting etc... He has typical bolt on mods running 1300cc injectors.

This car is being done by Dave at KDR and will be dyno-tuned in the next two weeks. What do all you think will be the dyno curve?? I think the peak will be close to 400rwhp with a real nice low end power curve. I will post all my results. Dave told me this is a really nice turbo kit, I'm optimistic.

Hey enzo250,

It does suck anus hardcore that stuff gets modified, I know this thread was great, it showed all sides of the situation. Finally resulting in the company in question testing their car on the drag strip and getting some figures.

The figures were quite bad for a car that was meant to make so much power with very little lag, I think they were in the 11.5 odd second range with a speed in the high 117mph or there abouts when being prepared for the track, all sorts of excuses were offered at the time explaining the lack of performance etc.

Basically nothing added up in their claims, it was realy interesting to see people come out of the "wood work" to voice their opinions on this thread, also some of the responces from XS were interesting as well, it is a real pity that ALL this stuff has been "LOST?" Especially some of the responces from XSPOWER realy showed alot, it is a real pity that all this information is no longer in this thread.

All we are left with is a gutted out piece of crap, with no real input from others, no real questions, no real answers...it is a real pity.

I just want to state again that, in the last few pages of this thread I showed that the claim made by this company was doubtfull to be nice about it with the information they provided to us, and their track performance backed up what I and many others who contributed to this thread had believed.

Not trying to get anyone going here, just trying to finish off the thread as it was (from my side) cause as I found it when I did a search it was HIGHLY misrepresentative of what happened from my point of view. It was interesting to see how many people responded with doubts well sfter I stoped contributing to it after resukts if the cars on track performance were posted, it was very interesting.

Maybe it was too factual for some people, hence the reason most of the good information got delete or "lost" from it ?

Boostn7

There are posts which are missing.

Yeh ! their claims are right on????

No one denies the hp claims...

*BUT* looking at the dyno sheet (tq curve) it's clear the boost is still climbing past 5krpm and yet they get full boost by 3.8-4krpm >simply put... the boost was higher then 1 bar.

And the A/F of 10.x:1 was quite rich to make that power without missing !!!

I think Rice Racing is talking about some posts to this thread that are misssing..if i rememeber correctly this thread had more than 2 pages of posts.. i didnt touch this thread, im thinking maybe some posts were lost in the "crash" or the switchover...????????
