That's cool... There's always a learning curve as combinations change, but I've got a pretty good handle on spec'ing the PTC's with Dusty. Sending you a PM!! Edit: Or maybe not... Hollar at me if you can!?!?
Thanks,

Interesting turbo/dyno test tonight= bigger isnt always better

I spent over 4-hours on a Superflow SF-600 flowbench 2-weeks ago flowing a couple different sets of iron heads. I would love to add a set of the VPE to that list if you're ever interested...
K.
I flowed a set of the VPE's. No better than any other ported iron I've flowed. Around 205 on our test bench just like Champions. I'm trying to remember the low lift #'s but I remember I wasn't impressed by them. They are a good quality head but no better than others.
Is it worth the extra $500 for the champion gn1 aluminum heads over the Cnc ported irons? My current mods and mods going onto car at the same time as heads r in sig, along with my goals.
Bc if they will get me to my geasing less boost or keep it at 27psi and hit 130mph then it's worth the money to me

Bison and Otto thanks for taking time away from your schedules to do all this testing.
Bison, would you recommend porting intake, heads, and adding plenum spacer before going to a bigger turbo? As mentioned by GNVYUS?
That's what I figured Dusty, but I'd still like to put them on this same bench with all else equal to the other's I've already tested. I have a couple different aluminum heads to flow and I'll post a new thread with all the info. at that time.

I dont see them making more power unported. If you were going to run a larger solid cam in there id rec them since they will accept larger springs easier. Other than that your looking at nothing more than weight savings. Running less boost to make the same power means more compression and more cubic inch with more converter required and better fuel. Its easier to run more boost and less timing and compression ratio in most instances. Boost doesnt break engines. unning 130mph with the parts you listed shouldnt be to big a deal and can be done with room to spare.
Depends on how much bigger. Porting the intake is a waste of time. Just cleaning up around the injector boss and squaring the port exit will make the intake flow more than the heads will. Heads are always a smart move and will make more power with less manifold pressure every time. A plenum spacer wont increase power but will help airflow distribution when the engine starts turning more rpm.
Ok...brian, if it was ur car and u had the mods I already have, what heads,cam,ratio rockers,valve spring wud u put on it to get 600whp on ottos dyno and 130mph on a full weight gn
Btw I'll prob have Otto(and u if ull b there) swap out my converter for something else. I think mine is a 0 pump and from what u told me to tight down low Sense ET/mph Is more important to me then a dyno number I'll prob want a ptc 9.5? Lu or nl?
Ive found all decent ported heads out there will out flow the valvetrains ability to let the engine breathe in most cases. It wouldnt matter if the heads flowed 250cfm if you are using them on an engine that has less than 70ci per cylinder and was under 6000rpm. The engine has to require more flow for the heads to be a benefit. Ex flow has more that can hurt it than the intake flow. Someone should figure out the reversion flow back into the cylinder. Then people would be able to see why increased CR and proper cam profile and timing are like adding a bunch of displacement.
About 8 years ago i went high tens/127-128mph Dave Reed's maroon T. It had 8:1, 234ci, journal 6776/.85, Cottons old intercooler, Champion heads/intake, stock rocker arms, AC16930 NL, old SMC, stock MAF with one screen, RA 108 chip and27psi. Converter slip was 15-18% and the car was 3800lbs with me in it. We were out of injector wit the 50's we had in it or it would have continued making a lot power if octane/timing and boost were thrown at it. With a 9.5" PTC it would have went 131+ on that tune. All the 9.5" are non locking custom converters and are designed to make the car e.t. A lockup will show more peak horsepower but less average road horsepower on the dyno. I would use 26918 springs today. I think we had 941's on that engine.
Would you mind elaberating on this a little more please Brian. This is what I'd like a little more info on this:smile:.
Two questions so it's clear to me if u don't mind..
1. So a 9.5ptc will clearly out ET and mph a vig 5 disc whether I lock it or not? But the vig locked will show more hp on the dyno, the ptc just gets it down the1/4 faster
2. Even on a factory unopened bottom end, are champion irons,ported stock lower intake to match, 1.65 RR, 210/215 cam.( unless u Rec something elsel?)
And whatever springs Otto wants in it and installed at whatever hight he wants....can 600whp and low 10s @130+ happen if I have u or Otto tune it at the track to fine tune after dyno?
Not afraid to turn the boost up

2 i ran low 10's on a stock bottom end well over 130mph and had a lot of time at WOT on the street.
You shouldnt need much tuning once it leaves the shop. 600whp will get you more than 130mph.
Ya I figured. I just wasn't sure if all u had to do was dyno tune it and that's it.
Bc I no u can't tune 1st or 2nd gear on the dyno. So I thought u had to do that on the track. Bc I don't wanna become of those cars with nice 60' but running high 10s @131 when most with same 60' r low tens at that mph(if that makes Ne sense haha)
Btw. Thank you bison for helping people like me...I know sometimes it prob gets irritating Bc u prob answer the same questions from different people time and time again.
Thanx again for all ur input and hopefully I'll get to meet you while the cars there
TE44 dyno'd today
I dyno'd my TE44 today. 422rwhp and 511 rwt at 27 lbs of boost/93 alky/exhaust cutout removed. first dyno pull was with cutout capped. Stock cam, stock heads w/ mild port by me, 177/150 valves. See other mods in signature. Attached is my PL file. Can someone look at my datalog and tell me if I have more HP to gain by tweaking tune with current setup. Also would 210/215 roller cam help alot? Heads have been decked to remove the O-ring work done by previous owner so CR is more than stock. If I should post elsewhere, let me know.

Well looks like you need to add a bunch more fuel, and based on the WB data, I would say its misfiring under high boost. I would say the injectors are big enough but your fuel pump is not keeping up maybe. BLMS are at 170 maxed out the injectors are close to 87-90%. Or turn up the fuel pressure 5 psi. WHen you start seeing the a/f ratio bounce every bounce is a misfire. I have learned from experience. Coming up on boost it went lean and knocked, not a good thing. You may want to richen overall system fuel on the chip, but the duty cycle seems high its a fuel problem somewhere.
Since you are dealing with a small turbo id be looking to increase the road horsepower not the peak power. Id avoid a larger camshaft. Instead id look at running a taller tire/removing a little gear, running a higher octane and increasing the timing up to about 24*. All assuming you are not running out of injector or dont have a fuel delivery problem. You are trying to propel the small cam/turbo application with cylinder pressure rather than horsepower. If you increase the rpm limit you will bleed off too much down low and it will be a turd with the small turbo running out of breath. Id get some dragstrip numbers and see where you stand.
Thanks. Yes, could be fuel pump. I was told it was a Walbro 340 by the previous owner but he was misinformed on other items by his previous owner so I would not be surprised if the fuel pump is not a Walbro 340. I will check fuel pressure tomorrow. I believe I had it set at 43 with hose off.
Since you have a power logger, why not record fuel pressure at the same time? The sensor is a bit expensive, but well worth it to me anyway. You will use input #4 and configure it as a 100 psi sensor B. You might get a discount If you say norbs sent you, or maybe he will jack up the price, LOL Kelly is great to deal with.
I am impressed with your numbers so far te44 is a great little turbo for the street.

WB-762 is the sensor you need.

I will check fuel delivery. I didn't want to buy a camshaft anyways. Current tires are 255/60/15. I have been looking for MT 275/60/15. Funny you say add higher octane because I just found out Sunoco station down the road sells 110. Current timing is about 21.5* so certainly room to cautiously move it up. I had plans to go to dragstrip 3 times this year and each time something came up so I had to cancel, but I know I need to get there. Thanks for the comments Bison.
