My favorite characteristic about this swap is that he used brainpower to find a better power adder.
As opposed to starting a thread: "What do I need for xxxWHP"
I want to know how you got 1.8's for $30 lol, unless that's a miss-type.Odd...when I put mine together it was like this: Heads cost me $700 Brand new full S3 WBS IC with new meziere pump cost me $500 Gen V cost me $300 And those 1.8's I added onto the top of the cam with the added lift.. $30 Total cost $1530 ... I still agree that the TVS looks like a better option if you want to stay with a blower. BTW...does it have some good blower whine?
How do you call a cam, headers, N*, 2.8 pullied motor just a cam-only motor, even "for short"?
You say nothing of relevance changed between 299 on the gen v and 350 on the TVS, but you changed injectors and a fuel pump. If you were out flowing the injectors AND pump on the TVS, how were you not on the Gen v?
What does your 350WHP Street Tune have for timing?
Was E-60 used on both gen V and TVS dynos?
So we're all set now... The TVS has been on 2 different dynos with multiple witnesses, here's a run down of past events in a nutshell.
Mods:
GenV w/ MPS
N*/LQ4
SSAC Headers, no cat
Stock Grand Prix GT catback
Cold air/Open cone intake
XP cam with 105# springs
DHP/wideband tuned by me
I call it a cam-only L32 for short.
This setup made 299whp STD. This number was highly contested as being a sandbag number... It's true I made more uncorrected power in the dead of winter, but the corrected numbers were right around that figure. I don't remember exactly but +/- 5hp. This number was attained with a spot on tune, AFR that was locked in and on point and timing was on the cusp of what it would handle. Bottom line is that it wasn't making any more power, period.
Anyway I swapped the TVS in place of the GenV and immediately found out that I was going to need more fuel. So I upgraded to 42s. Those weren't enough so I did 60s with a racetronix pump. That setup made 350whp on a base street tune and 2.8 pulley, 3rd pull. I wasn't able to dial it in any better as I was off the dyno after 10 minutes.
Once those numbers were released, it seemed like everyone had an issue with it. Either with those numbers, the dyno reading high, me lying about something or whatever. Bottom line is that the GenV did 299 and the TVS did 350 with nothing else of relevance changed.
So now we come to today's results. The TVS setup remains the same (2.8 pulley) except for this run was open down pipe and I was using e60 (tested and confirmed) fuel. It's about 102 octane. Winterblend ethanol, what are you gonna do?
Can you do a cost breakdown of it? Of those that you listed that the TVS wins, cost and reliability are the most important to me.
How do you call a cam, headers, N*, 2.8 pullied motor just a cam-only motor, even "for short"? cam-only means the engine only has a cam... obviously everything else is clearly listed.
You say nothing of relevance changed between 299 on the gen v and 350 on the TVS, but you changed injectors and a fuel pump. If you were out flowing the injectors AND pump on the TVS, how were you not on the Gen v? the injector and pump issues were irrelevant because the limiting factor was knock, not fuel. the TVS flows more air and boost before knock is a limiting factor, therefor fuel became an issue when more air was introduced.
What does your 350WHP Street Tune have for timing? Something like 16 degrees.
Was E-60 used on both gen V and TVS dynos? No. This is abundantly clear in every post. I've gone over exactly what each dyno run consisted of at least 68 times.
Edit: How many PSI were you seeing on each S/C? 11-12psi on the GenV. 14-15psi on the TVS. 11-12psi on the TVS with open down pipe.
