Drew, did you have a chance to do any dyno pulls at Gintani (baseline or FI)? Just wondering how it read in comparison to VF's dyno. Numbers aside your car was FLYING in Mexico .

HFS...

Here i was in my little "I'm content to keep my car mods NA" world and you had to go and post a vid like that!

Your link might turn out to be the most expensive one i've clicked on since i found my house on HAR.com...

Congrats to you and Gintani on creating a f*cking BEAST of a car man!

Yes, but when the motor hits the rev limiter on the dyno and the TB's close there is a spike, hence the reason the boost level shows a higher peak boost, and sometimes they are abnormally high. PG's FI dyno's show this as well, there are spikes that are approx .5 - 1psi higher than the actual boost level on his dyno graphs too, same DJ.

The car didn't make bigtime power on 91 as other Gintani cars have on a DJ, I do have cats, regardless it made the performance #'s on the road, the latter means more to me. If anything it's exciting because I think there's more power to be made with the Meth as well and hopefully even better performance#'s.

Can you help me to understand something or clarify it for me. I recall Niterider's dyno (in dyno db and also dynojet) putting down like 505 whp and 345wtq at 5psi. I noted this last year as it was before my SC decision and I was evaluating SC options. Here is my question, why doesn't your dyno show more of an increase than 10whp when you have 8.75psi and water/meth? Both cars have exhaust and I would think that increase in boost and water/meth would make at least 50whp more? If that increase in boost and water/meth only increased whp by 10 it doesn't seem worth it to me at all, IMO.

Maybe some guys at Gintani can chime is as I'm sure they have some R&D dynos with more info and details. It just does not make sense to me.

Different dynos brotha. Drew's car has put down the quickest 60-130 time, so obviously the power is there .

Yes, but there are usually slight spikes at or near redline. With my old AA kit I would spike as much as 4psi over what I was supposed to be at becuase the blow off valve was too small for the job.

The DJ didn't look like it was at VF based on the video.

I answered your questions about the peak boost #. AS PT pointed out different dyno's as well, I have cats, Brian doesn't, DCT vs. 6MT DT loss, what gear did he dyno in, etc.?

As it has been stated earlier the car does not have aggressive tuning to take full advantage of the Meth, this was my choice, what you think has no bearing on it. I am running two small 175ml nozzles, it is used for additional cooling ONLY, because I wanted it.

Does 60-100 in 3.5s, 60-130 in 7.7s and a 130 trap make sense? Is that worth it to you? Larry, I just got the car, there's more to to do.

+1 cant compare the dynos. I dynoed at a different place, different day. Many dynos at different shops are set up differently. Thats y the best way to get as consistant dynos as possible is to dyno at the same place, before and after mods.

As u can see, many other SC cars have dynoed higher then Drews car on a DynoJet as well, however the numbers Drew has 60-130 are faster then any of the e90/92 SC cars out right now. So the only possible answer for this would b A) other dyno numbers were false claims or B) is it just because of the different settings used on the dyno, different day etc...

Im gonna go with B. Just because I have seen this first hand. I seen how much of a difference a different dyno can make. Ive had my car have up to a 60whp difference with the same exact set up but just a different dyno.

[niterider]

And as far as the spike goes, this is mainly because on a dyno the car bounces off of rev limiter. I have seen hooked up cobras/corvettes with after market whipple blowers and Vortech blowers spike up to 2.5 psi higher then the running boost. However the Dyno will normally record the highest boost level which will always be the spike. If u actually monitor the boost when driving the car it will never get the boost levels as high as the spikes does on the dyno, well except if ur belt slips. Ive seen that happen too.

And Drew I showed like 10 different people ur video, it is so cool , I cannot get over it. Even people who could care less about cars like my sister and mom and stuff were like "thats really cool, is his car coming out on a movie or something?" lmao. Thats exactly what my sis said.

I'm aware of the times and I'm not saying anything about them. So the answer is different dynos? Are you saying that two dynojets can register more than a 50whp difference with the same car? . I am just trying to understand how much power difference there is with Drew's setup, 8.75psi and water/meth, compared to another gintani kit with 5 psi. Just doesn't add up to me. I think that the forums and future SC owners need to understand.

Ok well first off, he is not running 8.75 psi, thats just a spike, he is at 7.5psi and the meth is JUST FOR COOLING. Second their is a lot of factors that come in to play with dynos. Again, the dyno settings as per the user, the exhaust set up, the transmission, the weather (which some dynos compensate for) again that depends on how the dyno is set up, the gear etc.

Im sure many people on the forums are aware of the dyno differences and how they affect numbers, it has been pretty beat to death. This is why I think comparo runs with other cars and V box numbers are a lot better to use when comparing vehicles. IMO of course. Hopes this helped

Why are you using 8.75psi for Drew's car? Did you not read the many responses above about boost spike? Drew is at 7.5 psi. Did you just fail to comprehend the other things posted abotu different transmissions and possibly different gears? Didn't PG show how much of a difference dyno'ing in various gears can show?

I think most of them do.

Is it hard to believe that he actually posted the information you wanted to hear and yet someone still finds a reason to complain? You keep saying Brian vs Drew. 6MT vs DCT (Different gearing, different dyno) So it's not apples and apples.*

Can I see your dyno sheet with boost, af/r, etc, blah blah? Drew has nothing to hide, his car is a beast. No corners were cut, everything was legit, he even used full 91 gas... He put his car to the test, he even went to the dyno that PG went to so you can't complain and say gintani cheated... Why is it SO hard to believe? *

I'm sorry PG, but your situation was different. We were wondering how you made 40rwhp more with less than .5psi more boost. Which we later found out to be due to different gear dyno runs.

You guys are trying to compare different cars, on different dyno's, on different days, with different transmissions, probably different gear on the dyno run, and both cars have different supplemental mods.

I can see where you guys are getting confused why 2psi more only made 10rwhp, but all of the above needs to be taken into account.

Hell, even HPF cars, on the same dyno, will be as much as 30rwhp apart.

He is? Who demanded anything from your dyno charts Robert? You posted up dyno's without telling us what gear you used from each pulley! I'm not so sure the two correlate. But yes people have been extremely hard on you at times, and much of it has been unwarranted.

Honestly your the only one that doesn't understand.

Again, Robert, your situation was different. If Drew showed us 2 dyno's, one with 7psi and and one with 7.5psi, and he made 40rwhp from one to the other, you better believe I would agree with anyone questioning it. Again, you can't compare your situation with his.

Questioning your dyno numbers was a valid concern, which was shown to be due to different gear selection between the two dyno's which was not disclosed initially, what you guys are doing here is not.

Robert, my situation does not necessarily correlate with yours, I never predicted/claimed anything or even spoke about my car being SC'd until this post. Do you think Larry feels the need to continue to pursue it this way because of how you may have been treated in your dyno thread or because I choose to go with Gintani? Or is it for other reasons? Because he sure didn't ask about your peak boost being higher. It's interesting, another ESS guy "bigpuna" asked me simular questions, either I'm nuts or I see a pattern here. I appreciate you not choosing to go that route!

I think the questions asked by E92MMMTHREE were VERY fair as were biglare's initially and bigpuna, I've asked the same questions in the past. But do you not see here what Larry is attempting to do here? Though he will claim innocence, lol, I've seen it in other Gintani threads.

I think it's fair to ask why I dynoed less than stellar #'s with more boost and Meth compared to Brian and others, when I heard I was a bit underwhelmed, lol, but after I drove the car, saw the Vbox data on the 1st night I got the car, I was absolutely ecstatic!

Then when I saw the comparo runs with the M5 and 997tt, I knew the car was making the power, but just like you there's always more to do to go faster and make more power.

Listen I'm not these other guys, I'm not upset with you, do we disagree at times? Of course, but I flat out love what you are doing with your car and how you share it with us, that's all I'm trying to do here as well, but honestly these questions are not tough or harsh, lol, and to some the answers aren't satisfactory, fair enough of course there's legitimate questions that should be answered, but if people want to doubt your results or be negative most of the time, every forum has a few, I say f 'em.

Why dont you all meet in Mexico and see who is the last one standing? Who really cares who has the fastest/most powerful paper E9X M3 anyways really?
