I agree with all of you 100% on the numbers our big turbo kits are making on pump gas.
No arguements.

Nobody has done a tune with the turbo we recommend yet, the BR440 kit. This is a street turbo, we made 401 on pump gas with it compared to 360 with pump gas on the stock turbo.

On race gas we were able to make 443 with this turbo kit and on race gas with the stock turbo we only made 390. About a 40-50 whp increase with this kit.

The bigger turbos are meant to run in a total different area than the smaller units. Nobody that knows turbos are going to argue that. We had a bunch of BR440 kits sold, as soon as the BR500 kit was done everyone wanted the bigger turbo and changed their orders.

NOW, as a side note, I don't think anyone has done the BR500/580 turbo justice on pump gas yet. While I don't believe they will make 450 whp I do believe the numbers should be over 400. On the same note, the BR440 will spool like mad and do just over 400 also.

I think the BR440 kit what most guys should run, everyone is power hungry. Problem is in order to make big power numbers in a turbo car you have to run higher boost, atleast with a small displacement engine.

Yes, we can get you in to tune and install the turbo kit you have, give us a call.

i have an rnr kit here, should have dyno numbers next week. That will be on pump with the aem. Alot of companies are using the regular garrett non ball bearing precision turbo's. The rnr kit also has this turbo. Looks like a 50trim. Will be interesting to see the results.

Mark, hows the whole thing going with Ron's car

 

That's funny and wrong.

As for the numbers, it should be pretty clear that what we are seeing is the difference between dynos. Pruven's dyno reads high. During my dyno days at Pruven, Stage 1 cars were putting down 310-320whp on the basline map with no tuning. This is nearly 20whp higher than what they put down at Turbotrix under similiar conditions. If anyone wants to play the numbers game, stick with one dyno and stop comparing apples to oranges.

my 2c,

shiv

 

Well I am glad I could amuse you Shiv. Could you please go back and read what was going on with the car, you must have missed my post about him adding parts and then the car having misfires and Marks post confirming this and saying it was rich off the scale. This would mean there were problems, not just a "difference" in dynos.

The car is getting re-tuned in the near future.

Not everyone has a M@@N dyno , and if you read the rest of the post shiv you would see that he did change things like David just said. Go back about 2 pages and look at my post and you will see some of the changes to the car

 

Wow...if that's true my peak numbers (288 hp and 295 lb - ft. torque on Pruven's dyno) kind of suck for my mods. It was a bit humid when my car was on the dyno and the buschur parts do drop about 50 lbs or so. The car seems a lot faster and I'm pleased with the results, but those numbers would seem a bit low.

 

I'll second this ^ ... why? Because I got flashed at Turbotrix and I made 291whp on their Dyno.

My friend (won't say his name) got Dynoflashed @ the Pruven Dyno. He made 322 whp.

We both were on the highway.. and he wanted to test out my Turbotrix's Evo-Flash vs. his DynoFlash. We both dropped it down to 3rd to then 4th and so on. He beeped the horn 3 times and we went. On this OPEN highway, I pulled on him and beat him at least 3 car lengths.

So this makes me think. Wow, does the Pruven dyno actually read more ... we all know the answer to that one

Just my $.02

 

DAMN!! So I would be making like 390whp on the pruven dyno on pump gas?? I should get that chart just for bragging rights LOL Bah 366.5 on a real dyno is more than good enough for me.

 

Three car legnths is alot!!! What kinds of mods did he have and what do you have? Cause three car legnths with simmilar mods is a big feat.

 

Wow, I knew this couldn't stay civil. And I think shiv was commenting on "wrong" in reference to the hexadecimal code and the intake.

What doesn't make sense to me is a larger turbo should do better on pump gas, not worse as David is suggesting. A larger turbo should generate less heat at lower boost levels, and we're not talking about a turbo that is too large to run at 21psi comfortably. So, shouldn't simple physics make this turbo perform well on pump gas? And I'm not trying to start anything, these forums are open, and I have given BR $1500 dollars of my money, quite hapilly I may say, so don't start accusingn or name calling.

And yes, there are dyno differences, everyone knows that. To make it seem like there's not is wrong. Read the last sport compact car.

 

its funny cuz we both have the same mods just not the same brands.

I have K&n typhoon intake, Turboxs cat-back, turbo xs DP, random tech HIGH FLO CAT, Unorthodox Racing Upper and Lower I/C pipe kit, Hallman MBC.

He has RMR intake w/ Ralliart induction pipe, JIC cat-back (titanium), JIC DP, and a CAT DELETE PIPE, Ralliart upper and lower i/c pipe kit, HKS EVC 5 boost controller, and he had a fuel pump (which I didn't have one)

yea, it was almost like 3 car lenghts

 

How about driver skill/performance?

 

we are about the same.... besides.. how hard is it to shift a car .. what skills do you need to do that, and let the car do all the moving?

 

Its easy to misshift or just shift up at the wrong time/rpm. Shiv is saying there is 20 WHP or so difference between the dynos and your bud measured about 30 WHP more on the pruven dyno (I assume both have decent power through the rev range), it just doesn't makse sense for you to beat him by like 3 car lengths unless it was due to the driver or his car wasn't running right at the time.
