Intercooler upgrade, ported head, stock size ss valves, degreed hr70 cam. 7-1 pistons. 2g mas, 850 / 1400 injectors. Race gas blend. Tuned with Neo afc and Innovate logworks data logging. First run about 21 psi average. Boost was choppy. This is a spikey turbo. We leaned out the turbo spool up and tweaked the fuel a little up top. Last run 25 psi average. The boost trace smoothed out some as we raised the boost. We let it cool for the last pull and made sure the intercooler was fully cooled. But could not get 300. Made 300 uncorrected, does that count? The extra boost and tuning mostly helped the torque. I am really pleased with the torque.Edit, I also gained hp in the 3500-4800 rpm range. It was just the peak hp that stayed about the same. Shop wide band was reading .6-.7 leaner. I need to do a recalibration. I meant to do it beforehand. My car still has some of the 1.75 intercooler piping on it, that will be the next upgrade.Edit, this turbo really should have an external waste gate. That would probably add a little power as well as better boost control. My short block was pulled from a parts car with a sized motor. It turned out to be a fresh stock rebuild that spun a bearing and locked up when an oil line failed. I replaced the crank, bearings and head. The head was replaced again last year. I have been flogging it for 4 years. I do not understand why people do full rebuilds on motors with fixable problems and spend tons of money on everything but what actually makes the power. http://i237.photobucket.com/albums/ff45/StarquestRescue/Data%20logs/DSC02132.jpg http://i237.photobucket.com/albums/ff45/StarquestRescue/Data%20logs/DSC02131.jpg http://i237.photobucket.com/albums/ff45/StarquestRescue/Data%20logs/18gtdo5hDyno.jpg http://i237.photobucket.com/albums/ff45/StarquestRescue/Data%20logs/18gDyno2ghz.jpg Edited April 28, 2013 by StarquestRescue Quote Link to comment Share on other sites More sharing options...
BOOSTED88tsi Posted October 2, 2010 Report Share Posted October 2, 2010 Thats tight! I agree with the crazy rebuild comment, ran my truck at 28 psi multiple times on a hx35 with stock rebuilt bottom end! Quote Link to comment Share on other sites More sharing options...
jahjah Posted October 2, 2010 Report Share Posted October 2, 2010 congrats on the power I do not understand why people do full rebuilds on motors with fixable problems and spend tons of money on everything but what actually makes the power.reliability and longevity?

StarquestRescue Posted October 4, 2010 Author Report Share Posted October 4, 2010 way to go john!! and yes there is something to be said about teaching new dogs old tricks!!The tricks are not new. Just proven tuning concepts from the dsm world, that are seldom explied to tbi cars. The 18g is proven low 300 hp capable on the starquest. It is kinda a wild animal as far as boost spikes and tuning. I need to look into an external wastegate. 100+ more torque than horsepower, those are V8 numbers.Excellent job John, those are fantastic numbers.Thanks everyone Awesome, bringing to the track anytime soon?Yes, i have already run a 13.1 @ 105. I think i can squeeze a high 12 out of it. I want to work on the street tune and boost control more. Quote Link to comment Share on other sites More sharing options...

psu_Crash Posted October 6, 2010 Report Share Posted October 6, 2010 Very Impressive!! Probably more torque than my "m pee why" Holset monster puts down! :mad: Quote Link to comment Share on other sites More sharing options...
modifyd Posted October 6, 2010 Report Share Posted October 6, 2010 (edited) Congrats on the numbershttp://www.starquestclub.com/forum/public/style_emoticons/default/biggrin.gif Where did you get it tuned? I am kind of skeptical on tuners but i would drive a distance for a reliable one. Oh, and I could pick up that Conquest stuff!

dmyers151 Posted October 6, 2010 Report Share Posted October 6, 2010 I'm pretty sure he does a majority of the tuning himself on the street and at the track. Then uses the dyno for feedback to do the finer tuning. Quote Link to comment Share on other sites More sharing options...
StarquestRescue Posted October 6, 2010 Author Report Share Posted October 6, 2010 Congrats on the numbershttp://www.starquestclub.com/forum/public/style_emoticons/default/biggrin.gif Where did you get it tuned? I am kind of skeptical on tuners but i would drive a distance for a reliable one. Oh, and I could pick up that Conquest stuff!I tune it my self. I have two Innovate ssi-4 data logger boxes on the car. Tuning is done with a neo afc. The 2g mas makes the car run 20-20% leaner, this is a help as my injectors are 43% bigger than stock. I am adding up to about 20% fuel at low load and subtracting about -10 at high load. Bod Brady, the dyno guy was coaching me based on what the dyno graft was showing. I only paid for a hour. The 3" exhaust install was finished that morning and the ebc was hooked up a couple of days before. http://www.bradyshighperformance.com/Mostly a v8 guy, but i know some of the front wheel drive guys get tuned there. 2wd dyno. He keeps asking what kind of car it is. Quote Link to comment Share on other sites More sharing options...

StarquestRescue Posted October 10, 2010 Author Report Share Posted October 10, 2010 (edited) Current picture. I ran a different bov on the dyno. The one in the picture leaks 1 to 1.5 psi at high boost.http://i237.photobucket.com/albums/ff45/StarquestRescue/Data%20logs/StarquestRescue297hp403tqtbi.jpg Is your Throttle body ported?Yes, but i consider that mod a small potato. awesome numbers johnThanks Is that like a skin graft?Spell check fail. Well i put 5 gallons of e85 in it today. Gas gauge was a little over E. I added 20-25% fuel to get home. I will probably need to add more after the last of the gas is run out. I am going to run out of injector flow real quick. Hopefully i can run 20 psi. I did not do a tuning pull yet. I really need bigger injectors for that. I was at 92% duty cycle on the dyno with the 850/1400 injectors. Edited October 10, 2010 by StarquestRescue Quote Link to comment Share on other sites More sharing options...

I'm sure when you get the small end hacked off that OVC pipe and do a full 2 1/4" all the way through your numbers will improve even more. You said a intercooler upgrade, what type is it? I can hook you up with the 1600cc injector, just let me know when you want it. Its $115.00 plus shipping and PP. Keep up the good work Edited October 10, 2010 by brianpaul98 Quote Link to comment Share on other sites More sharing options...
Technology Posted October 10, 2010 Report Share Posted October 10, 2010 $115 for a single 1600cc injector? I think that made baby Jesus cry a little. Anyway, e85 is the best, it smells like an old musty sock at first, then it starts leaking out here and there and starts smelling like booze, then a while later it starts smelling like horsepower, then you want e98 like you actually needed it, but only for the smell. Just kidding about the leaking part. lol. Quote Link to comment Share on other sites More sharing options...

jinx Posted October 14, 2010 Report Share Posted October 14, 2010 18g considered too much compressor for a std 05h turbine wheel, I imagine its clipped? big torque swell, then characteristic g54 nosedive. Reckon its the stock starquest turbine housing/wastegate arrangement, or the bad airfolw path of the stock manifold now limiting the hp ?The "350hp" tbi car had neither.... which also makes me wonder, what that exact cam would do for your 18g setupSeems like you're just the type of guy who sweat the details, to yield standout results. Well done Quote Link to comment Share on other sites More sharing options...

Well doneInitially i was leaning towards a shop built td06 18g, ended up with a home built tdo5h. The ChrisViper 18g cars are td05h with external gate. The dsm guys seem to favor the 05 over the 06 with an 18g compressor. In hind sight i should have went with the shop built turbo. I think my home build is on the way out. I still think cams and head porting is overrated. Same with headers. A external gate should help keep back pressure in check. I try to focus on bang for the buck and the least work.
