This afternoon I am excited to share some more dyno results from our good customer and friend FireDan50. He informed me that this appears to be the current stock block HP record? FireDan has built up an absolutely beautiful 370z over the years he has owned it. It has been a pleasure to work on the car with FireDan since his return to the states early this year. It has grown from 422whp with the Stillen supercharger kit which had a short lifespan unfortunately due to some sort of failure from the Vortech supercharger used in the kit. He was pleased with the performance of the kit, but had some concerns about how satisfied he would be long term with the power potential available from the supercharger set-up. He ended up getting one of the VSR top mounted turbo kits installed and said to hell with the supercharger. We already shared the pump gas results which we saw 496whp at about 8PSI which was also posted on this forum. He wanted to get the most possible out of his current set-up and we began to discuss the wonders that VP Racing fuel can do. We decided to pick up some Q16 and see what she would run. This stuff is so detonation resistant a child could learn to tune on it! Still takes true experience and skill to get the power out of it though:tup:. We saw the car creep up to about 535whp at the same 8PSI of boost that it came in on, but the 6266 is a fairly decent sized turbo and really prefers a little more boost. Out of curiosity we started to inch the boost up. By the time it was all said and done we saw a 611WHP rip at 10.5PSI. This was also where we found the limits of his stock MAF in the 2.5" intercooler piping used with the VSR kit. Being that FireDan50 is still on the stock block, we said we will leave the MAF upgrade and more power for a later date haha. Being leaded and oxygenated however it allowed us to run a leaner AFR and still make smooth reliable power.

Z Nationals update!:
Looks like we will be moving to an AEM TRU-Boost set-up in the future. At the Z Nationals dyno competition he tried to adjust back up to 10.5PSI but only got it up to about 8psi. The adjustment on the cheap prosport boost control seems to be hit or miss.... which isnt ideal. The TRU-Boost will allow us to store two different boost settings in the gauge, and we already have the quick map switching set-up via the UpRev software. Should be a whole heck of a lot easier to make sure hes hitting the right target boost.

He still won highest HP 370z/g37 at Z nationals even at only 8PSI! Congrats Dan!

I love it.. I want a Twin Scroll so bad, but BoostPerformance isn't building them yet. VSR has been getting better on there kit assemblies. When they first started that kit the welds looked rough. The kit is much better than it was! You guy's are awesome getting them tuned just right. I almost drove up there to have mine done by you. Might still do it this winter.. Keep up the awesome work :tup:

Thanks a lot man, I appreciate that! We would be happy to help if you decide to make the road trip:tup:.

Yeah the kit looks pretty solid. I think it could use a better intake system. We actually removed the filter for the racegas tuning. Also I think they should upgrade from the ProSport boost controller to something higher quality haha. Otherwise its hard to argue with the results!

Thanks,

X2 :iagree:, I got suckered into the ProSport Gauges if the Boost Controller is anything like the gauges anything would be better :icon18:.

I'm not sure if it's a record or not, but I couldn't find a higher number on here for stock blocks. I know there are guys with built engines that could put down some crazy numbers but maybe they're not as crazy as me with a stock block lol.

Alex, is the torque numbers right that you mentioned up top? The graph looks like it's showing 517 ft-lbs

Good god those numbers are sweet. I really cant wait to turn up the boost on mine now.

Ah damn, thanks Dan I actually forgot to adjust the RPM for the peak power as well. Thanks for the correction bud!

Pretty cool! Congrats. Reliable is a key word.

What I read about Q16 on VP's site is that you actually have to run more fuel than you normally would to maintain a safe AFR.

Being oxygenated doesn't change what AFR is safe, being leaded may, but it'll also foul your O2 sensors and destroy any cats still in the system.

Cool for bragging rights on the forums, but kinda useless @ $16+ a gallon and more likely to destroy your expensive sensors.

They have a few oxygenated unleaded fuels that would have been cool to see, though. Maybe you can try those next time?

:tup:

Haha absolutely. A beautiful car like the 370z is deserving of something more along the lines of a DEFI gauge versus ProSports.

The motors are absolutely incredible. They seem to rival the cast iron 4g63 at power hold capabilities. We have just blown away with every VQ37HR we've tuned. We have some pictures of one that we did a basic rebuild on our facebook/instagram where we got hands on experience with the cylinder heads. The intake camshaft set-up is pretty awesome and it was very cool getting to see how it all works. Overall awesome engineering makes for an awesome motor haha.

Well FireDan50 is a very responsible guy. He understands what he has and the Q16 is just for some fun and maybe a pass down the 1/4mi.

We were going to use the MS109 fuel, which we have used TONS of in the past, but opted for the more potent Q16 which has never let us down. It is leaded, but its not going to destroy sensors in a single dyno session. Used sparingly he should have no issues for some time to come.

As for your question/comment regarding the fuel, you can safely run leaner due to the detonation resistance you are correct. It does require roughly %5-%10 more fuel over a basic pump gas when it comes down to picking the right injector for your build if you intend on using an oxygenated race gas. Compare it to the way you can run leaner AFR on E85 thanks to it burning cooler and being more detonation resistant, but it demands 30% more fuel than pump gas. Also be mindful of brand as certain injectors do not like the MTBE oxygenated fuels.

Yeah, MS109 is what I was thinking of in my post. Some results on that fuel sometime would be awesome, both Turbo/SC and NA (like with Ecutek).

And I agree, a single dyno session or drag race pass here and there definitely won't kill anything. Problem is you get addicted to that power with all that octane and start running it more and more. :P

I would be happy to oblige with some fuel testing next time I get an opportunity. If the car still had OEM cats or HFC then we would have used the MS109.

Also you speak the truth about power. I have sadly reached the point in my career at Motion Lab that anything under 600whp isn't too special anymore haha.

lol, love the frank sinatra at the end!

sounds like a jet engine taking off!!:tup:

Sounds incredible. Solid ride.

Alex is that video a true simulation of how fast that car would accelerate in 5th gear?

These pulls were done without load in 5th gear. This would be similar to the way a DynoJet performs testing. The pull would be slower on the street due to additional rolling resistance, however the power output would be identical with or without load as far as graphed power goes as long as we weren't applying TOO MUCH load on the car during testing.

As far as our dyno goes we tuned FireDan50 to 496WHP on pump gas on our dyno, he put down 540WHP on pump gas on a DynoJet. Unfortunately he hasnt had an opportunity to compare our race gas results to a DynoJet yet.

Hopefully that answered your question :).

Yeah man! Thanks for the help! Awesome numbers on pump gas even. That's exactly where I want my car to be sitting for numbers on a dynojet

Its a hell of a ride! The Quaife rear diff upgrade really started to shine after the turbo upgrade. Definitely a well rounded build that if you were to replicate yourself you would be thrilled with the end result.

The only thing I'm really concerned of is what kind of fuel system I would need to run that kind of fuel and 2 is running race fuel really a cost effective move instead of just running an e85 tune which is much cheaper and more readily available?

Great questions! The fuel system upgrades weren't really dramatic as it was still a returnless style system with a single DW300 (320LPH) fuel pump. The fuel pump was at its limit, but we also ran out of headroom with the MAF sensors too so this was truly maxed out for the way the car is currently set-up.

We prefer the race fuel due to consistency. Also availability. E85 in our area really has dwindled down to almost nothing. The closest pump to the shop is around 30minutes away. Also getting back to the consistency aspect, to be sold at the pump the fuel must only contain up to 55% ethanol. E85 always gets worse in the winter time and when tuning for real power like 600+WHP on a stock motor, octane inconsistency can make for a quick catastrophic failure. Q16 will make more power than pump e85 in our experience. C85 would be a fantastic fuel to make power as well as it is pretty much e85 on crack.

Due to the returnless style system you end up maxing out your fuel system very easily even with large pump and injectors, as fuel pressure is actually dropping with each PSI of boost versus rising as it would on a traditional factory turbocharged car. Having said that though you really cant expect much more than 600WHP from a single 320LPH fuel pump.

Hope that answered your question somewhat.
