Dan your onto something here..your valve springs are also a couple years old...more boost will bring on the issue you are experiencing also.

 

So how looks this breaking? Is this something like misfire or fuel cut?

 

There are lots of scenarios that present themselves as an Ignition related misfire. Dan can tell you he experienced a bad cam angle sensor and once replaced it went away. Now we also suspect a weak or multiple weak valve springs might be a culprit of his latest problem. We have seen inadequate grounding to intake manifold/cylinder head also be a cause.
We also recommend the cdi harness be routed as far away from the cam angle sensor as possible as some interference can cause an issue.

 

do you just have a room full of old parts(not veary used parts) at home

 

Honestly dude i have no clue. Judging by how the car feels during the break up and the sound it sounds like valve float. I had this same issue 2 years ago. It was because i put kelford 272s on stock valve springs though, but it did the same exact break up. Im just thinking that its doing the same thing because there over 2 years old the springs are and been having this issue since i put the Kelford 288/280 in a couple months back. We will see exactly in the next couple weeks

It could be many different parts going on in there, i personally think its valve floats from the valve springs. I had a few people tell me that and i think that what it comes down to.

Exactly right! I moved my CDI box to another location and im wondering if its too close to the Cam angle sensor. But it seems to be the same length away now then it was so i dont think that causing any issues.

LOL no way man. I have to go out and by a Evo 8 head now. I dont just have that laying around in my garage haha. I wish i did. I actually do have a decent amount of parts but im planning on keeping till the end of the season

I have 2 heads at the moment that are available to me which looks like im going to purchase one this weekend. They are bare in great shape. I will be sending it out to get the full treament Monday it looks like ill be contacting Emery@ STM for the 650 cams and looks like were good to go. I also sold my ETS FMIC to my buddy local and going to a 5" core ASAP. The ETS core i had was the 4" and i think its a good time to upgrade Stay tuned everyone!!

 

i thought you were running last night. i hope all is well. you're usually quick with updates.

 

Na man car is down for a week or so to get the new head and cams and stuff. I will be back at the track in a couple weeks!

 

Those 8's better be here soon Joey

 

IF there is anything we can do to help, Do not hesitate to ask. You will get there soon, I am sure!

Very soon my friend! Going back out in 2 weekends is the plan!

Thanks Em! I appreciate it. Monday ill be calling u on buying those 650s!

 

Wooot more car parts LOL hunting down those 8 secs...

 

Yes sirrr!!!!

 

Joey,
Can you give a quick synopsis of your ownership of drag radials and slicks at the track...and your personal opinion of each? Thanks!

 

Sure no problem bud. Drag radials and slicks as everyone know are completly different when launching your car. Last year to this year i went through the Hoosier QTPs and now the M/T ET DRAGS. QTPs were a little easier to launch on. They were more consistent when i was on the Fp Black setup last year. What was also good about those, that they would spin a little bit instead of dead hooking. On the QTPs i cut a best 1.42 60ft.

This year went to the full slick. It was tough to get used to. When i went 9.1@156 we had to adjust the tire pressue and 2-step for that track day. Next track day, track was 2X more sticky, car kept on bogging so for a while that day we needed to figure out the perfect 2-step and tire pressure because all the car was doing was bogging. So far on the full slick i cut a best 1.40 60ft. With these tires you need to do adjusted to that track day. QTPs you still need to adjust but to me they seem more consistent.

Early this year i was thinking about going back to the Hoosier QTPs. But the car spins so much now as it is. People looking for what tires they want to use for the track it is honestly about what setup you have and track conditions. A couple years back I was on the Fp Red Stock bottom end/head/maf/full weight running 10.50s. I was on the BFG Drag radials. They worked out well for me and got me to the goal i wanted. My next step was the QTPs on the stock motor and go for 10.30s but the stock motor finally let go

I hope some of this info helped you out man. If you have any other questions let me know

 

Thank you Joey.

I guess a good question to ask would be, at what point (horsepower or ET) would you say that the QTP's become not enough tire and the transition to full on slicks is required?
