Is that a 70a/r open or divided?

I wouldn't worry too much about what others are seeing. I have noticed people exaggerate spool numbers. It's something that has to be datalogged for sure to know. Most people eyeball it think they are spooling sooner than they really are. Just make sure there are no boost leaks and no exhaust leaks before the turbine wheel.

Maintenance is a GOOD thing to do before strapping it down. Nothing worse than chasing down issues during dyno time.

I did search and have even been looking on link forums to see if I can find any logs with a similar setup and have not found any. Not trying to be rude but I want to see a log not just someone saying it should spool sooner. I hope it will spool sooner as well but I am not finding proof that people are getting these to spool sooner.

I know someone is gonna come on and say two diffrent cars and yada yada yada...all I'll say is that it's the same displacement similar compression and this guy actually built this to make top end power not spool fast and he still spooled by 4500.

Yeah considering the dyno I will be using is almost 4hrs away from me, I want to make sure everything is right before I head down there. I have found some boost leaks. One is the pcv and another large one is where my nozzel for the methanol goes into the intake tract. That is my task for next weekend is to get these fixed and then see if there is any more.

Slippi84, not to down ya but I will be the first to say that you are comparing apples to oranges. I thought it spooled sooner than it does untill I got to see my logs in link. Again I will say that I have some issues keeping it from spooling sooner but I doubt it will spool fully by 4500 rpm. Say what you wish. Feel free to post any comparisons you find of dsm or even evo's with a similar setup and then we can say mine is slow to spool but so far I have not found a whole lot of actual proof.

Reality is diferent. I don't know how big is the turbine wheel on 362 - indicer/exducer, but I have Holset H1E with 60mm inducer/ Comp.wheel/< S362. The turbine is roughly 73mm inducer/63mm exducer and I see 22 PSI @5100 RPM with 9:1CR, 280"s and JMF SMIM. This is according to a log from my AEM/no guess/. My timing is conservative-13*, but I don't have METH and this is not a small turbo ,so I'll leave my timing there for now. The turbine housing is T3 0.70 AR. Plus with a 8300 RPM redline, it is good powerband. The car begs for more RPM , but I wouldn't do it with my single/BC/ springs.

I atleast was comparing the same turbo. The 35r is a smaller turbo than the s362 and the s362 spools faster. Not to mention those two other things especially the 280's mainly are spool KILLERS.

I know, I just was giving an example. My car is in perfect shape and my turbo is a bit smaller.

I just did tons of searching on here and dsmlink forums and could not find a single post about spool with a s362 in any housing.

I agree you can't compare cars at all. I mean my friends rx7 sees full boost (26psi) with a t78 by 4,000 rpm. That is way lower than any dsm will get.

I found one log on link forums but the guy did not actually log boost. His boost est puts him at 15psi @5300 rpm.

Got a link to it?

Call martin at VIP or PM him and he can tell you all the info you need to know on the borg turbo's. Don't be so skeptical you said it yourself. You have a issue or two and have yet to tune and you get full boost around 5100. Andy4g63 like he said had a tip top car and it was tuned with a smaller turbo and he reached full boost at 5100. This turbo is made to be more efficent period. Just messing with your tune and adding timing and leaning out the a/f ratio in the lower PM you will see 300rpm sooner spool atleast. Maybe 4500 is the other side of the spectrum but 4800 should DEF be doable.

Here is the log I found.

I am not saying it is not doable but you come on here like you know so much about this turbo. Do you have one? Everything you have said is all hearsay which should never of been brought into this thread. All I can give is my experience so far. The little issues that I am working out are minor and I am sure the spool will be better once these issues are corrected like I have said many times before in this thread. What annoys me is that you have not shown any proof to back up your statements.

I do appologize if I come across rude in this post I truely don't mean to be rude just get tired of people saying things withoult ever experiencing them for themselves.

Seems like a pretty accurate rpm since his actual boost is also 15 and it appears as the maf is calibrated. I am going to try to find more and will report back if I do.

Don't be a ####y. Rev that motor! You are not doing any harm with 8,300rpm. I revved my car to 8,500rpm for YEARS with HKS 272/272 and STOCK springs/retainers with no issue.


Those BC springs with the 280's will not sweat anything south of 10k rpm. I would set the rev limiter at 9k and enjoy it.

^^ Took me a minute to figure out who you were quoting.

I don't think it's rude if you think that which is fair because your right I haven't given any of my own experiences. I have talked to 3 different borg warner dealers including bullseyespower and they all have said the same thing said. Marti has a system that alows him to put in your exact engine cams displacement compression ect.. and that comes up with the same thing. I have owned and ran two 60mm turbo's with spool characteristics similar to a s362 (GT14 and ebay t70 which is even bigger) Both of which spooled faster if not faster than your s362 is. I'm not trying to call you out just motivate you because while I haven't shown anything concrete to you that shows it should spool faster you have not shown me anything except your car and "estimates" from dsmlink which I have owned by the way and boost est is garbage if the car is not calibrated.

yea, that had me confused for a second too. On that note, I've zinged past 8500 on several occasions before with BC + 280's

I know but above 8K there is no power to be made .Even after 2-3 shift and it was"granny" shifting on that log, the RPM's drop from 8300 to 5300, so I am at full boost, 3-4 shift is even better it goes only to 6100.

That is why I know I won't regret my high compression pistons

Well I finally got the chance to dyno the car today and boy was it interesting.

We started with a first pull of 352.96 and 296.12 things looked to be going well as the second pull gained power with just adjusting fuel.

Well here is where it got scary. I decided to walk away for a minute to take a piss and in the process I got this bad gut feeling. All of a sudden I hear my car going on the dyno and then silence. I open the bathroom door to see the shop completly filled with smoke. My heart sank as I walked around to the front of the car to see oil all over the dyno. Result was that for the first time in my dsm lifetime I got to witness first hand the aftermath of a oil filter backing off at over 8k rpms. Well we roll the car off the dyno and while others start to clean the dyno I head to the store for a oil filter and new oil. Well today must of been my lucky day. We put a new filter on(extra tight) add oil and start the motor. Its a miracle it runs and no knock. Well I decide F it the motor will either blow on the next pull or not and since it was a 4 hour ride for me to take it home I would rather it blow on the dyno then leave me stranded on the way home. So we finish cleaning things up and strap her back down. Amazing, the motor seems fine. We made some more adjustments including adjusting cam timing and ended up with me deciding to stop it off at 430

Here is the long awaited baseline and then after tune graphs. It still has alot left in it but I am on stock internals that are about 3 years since the build and I rather keep it running safely (if that is possible) rather than getting a high number on the dyno.

haha what a story nice numbers.

Are you going to wire up a safty on you oil filter?
The car drove home too? , a DSM is so unreliable you cant even count on it to break down when it is suppose to.

Yeah I will definitly be working on something tomorrow to make sure this doesn't ever happen again.


Mine has been a good one and gotten me to my destinations. Was kind of cool being the only dsm at a evo dyno day and almost had the highest numbers of the day. Guy with a evo did 440 @27psi. I know I could of gotten higher numbers but I am iffy on just how far I want to push this motor.

I would be fine with 430 out of my setup. There is a 420a gy with 404 tha runs 11.09 so with yru awd platform and 30 more hp I don't see the need to get crazy unless it's a track only car. Def congrats

What oil filter housing are you running? I've heard of this problem happening from balance shaft removal. i know of a car that did this a couple times, and i suggested that he switch out his filter housing(91+ style) for a 90 style, or forward facing and he never did.. after a few incidents his crank finally snapped in half. Never knocked or anything though, just one day the crank split. not really sure if it was related to the oil filter blow offs or not. It seems to be more of an issue on the 91+ housing, at least from my experience anyways.

It is a 90 oil filter housing. I have never had it happen in 3 years and numerous dyno pulls in the past.

The balance shafts are out of the motor, it is on solid mounts and we were just ending a 8.5k pull.

We will see if the motor lasts into the winter. I am looking for a beater car I can buy cheap to commute to and from work and will be building a block this winter. Hopefully next season I will get to see the full potential of this turbo.
